Shortness of breath: treatment, diagnosis of causes, help

Dyspnea is the subjective sensation of difficulty, discomfort, or insufficient breathing. The American Thoracic Society defines it as a subjective experience of respiratory discomfort that can vary in quality and intensity among individuals. This is important because the same complaint, "difficulty breathing," could indicate bronchospasm, pulmonary congestion due to heart failure, hypoxemia, anxiety disorder, muscle weakness, or a combination of several mechanisms. [1]

Treatment of dyspnea should never be limited to finding a single "cure for shortness of breath." The modern approach revolves around two tasks: quickly determining whether there is a life-threatening emergency and then treating the specific cause of the symptom. Only then is it assessed whether the patient still has significant dyspnea, requiring additional symptom-based measures. [2]

In practice, this means that care for sudden, severe dyspnea and care for months of exertional dyspnea are not the same. In acute situations, airway management, oxygenation, ventilation, and the elimination of threatening conditions are important. In chronic cases, long-acting medications, rehabilitation, correction of underlying conditions, patient education, and restoration of exercise tolerance become paramount. [3]

Refractory dyspnea, a condition in which the sensation of shortness of breath remains pronounced despite the best possible correction of the underlying cause, deserves special mention. It is in this area that breathing techniques, multi-component support programs, gradual training, sometimes a palliative approach, and a very careful assessment of the benefits and risks of symptomatic medications are particularly important. [4]

A clinical article on the treatment of dyspnea requires more than just listing bronchodilators, oxygen, and cardiac medications. It also requires identifying who truly needs oxygen, who needs inhaled anti-inflammatory therapy, who needs diuretics, who needs pulmonary rehabilitation, and who needs immediate hospitalization. This is precisely the basis of modern clinical practice. [5]

Table 1. How to think when complaining of shortness of breath

Clinical situation	The main question	The main goal of treatment	Key sources
Sudden severe shortness of breath	Is there an immediate threat to life?	Stabilize breathing and immediately treat the cause	[6]
Chronic exertional dyspnea	What disease underlies the symptom?	Long-term disease control and improved exercise tolerance	[7]
Shortness of breath in chronic lung disease	Is basic respiratory therapy optimized?	Inhalation treatment, rehabilitation, hypoxemia control	[8]
Shortness of breath in asthma	Is there any anti-inflammatory treatment?	Inhaled corticosteroid therapy and action plan	[9]
Shortness of breath in heart failure	Is there congestion and is basic cardiac therapy optimal?	Unloading, basic cardiac therapy, rehabilitation	[10]
Refractory dyspnea	What remains after optimization of the cause	Symptom control, breathing techniques, airflow, palliative support	[11]

Basic principles of treatment

The first principle is not to blindly treat dyspnea. The American Thoracic Society emphasizes that the priority is always to identify and eliminate the underlying pathological process causing the symptom. If it's asthma, an anti-inflammatory and bronchodilatory approach is needed. If it's heart failure, unloading and basic cardiac therapy are required. If it's hypoxemia, controlled oxygen is indicated. If it's deconditioning, improvement will be incomplete without physical rehabilitation. [12]

The second principle is to distinguish between the sensation of shortness of breath and objective hypoxemia. Not all severe shortness of breath indicates low oxygen saturation, and not all decreases in oxygen saturation are felt equally strongly. Therefore, oxygen therapy should be prescribed not based on patient anxiety or physician habit, but rather based on objective target ranges for blood oxygen saturation and the clinical context. [13]

The third principle is to remember the role of basic long-term therapy. In asthma and chronic obstructive pulmonary disease, it is impossible to achieve sustained relief of shortness of breath without optimizing the daily inhalation regimen. In heart failure, the symptom rarely resolves for long without appropriate basic therapy, and in chronic lung diseases, the severity of shortness of breath is reduced not only by medications but also by exercise tolerance training. [14]

The fourth principle is to use non-pharmacological treatments not as an optional extra, but as a full-fledged part of treatment. Current respiratory guidelines support graduated exercise training, pulmonary rehabilitation, breathing techniques, multi-component support services, and directed airflow from a ventilator as methods for reducing symptom severity and improving quality of life. [15]

The fifth principle is to be extremely cautious with palliative pharmacotherapy. For serious chronic respiratory diseases, the European Respiratory Society recommends against the routine use of opioids for everyday dyspnea. However, in palliative oncology, the American Society of Clinical Oncology guidelines allow systemic opioids if non-pharmacological measures have been insufficient. This is not a contradiction, but rather a difference in clinical populations and goals of care. [16]

Table 2. What should not be considered a universal treatment for shortness of breath

Approach	Why is this a mistake?	What to do correctly	Sources
Give oxygen to everyone	Oxygen must be controlled and targeted	Assess saturation and risk of hypercapnia	[17]
Treat any shortness of breath with a bronchodilator only	Bronchospasm is only one of the possible mechanisms	First, determine the cause	[18]
Keep asthma on a quick-release inhaler only	Current strategy requires treatment containing inhaled glucocorticosteroids	Select an anti-inflammatory regimen	[19]
Consider home oxygen as a remedy for "lack of air"	It is indicated primarily in cases of documented severe hypoxemia.	Prescribe based on criteria, not subjective feelings	[20]
Ignore rehabilitation	Without training and education, shortness of breath often remains a limiting symptom.	Refer for pulmonary or cardiac rehabilitation as indicated	[21]
Use opioids as standard treatment for any chronic dyspnea	For severe respiratory diseases, this approach is not routinely supported.	First, optimize the cause and non-drug treatment	[22]

Emergency care for acute shortness of breath

If shortness of breath develops suddenly, rapidly worsens, occurs at rest, or is accompanied by cyanosis, confusion, severe tachypnea, chest pain, or a drop in oxygen saturation, this is not a situation for self-treatment at home. In the acute phase, the primary focus is on assessing vital signs and immediately addressing airway management, oxygen, ventilation, and urgent hospitalization. [23]

Oxygen administration in the emergency room should be controlled. The British Thoracic Society recommends a target oxygen saturation range of 94-98% for most acutely ill adults, and 88-92% for those with known chronic obstructive pulmonary disease or other risk of hypercapnic respiratory failure before blood gas measurements are performed. This is crucial because excessive oxygenation can also be harmful. [24]

In acute asthma exacerbations, current strategies include rapid assessment of severity, repeated doses of a fast-acting bronchodilator, oxygen as indicated, early initiation of systemic glucocorticosteroids for moderate to severe exacerbations, and, in severe cases, the addition of ipratropium and consideration of intravenous magnesium. The Global Asthma Initiative also emphasizes that severe exacerbations require immediate referral to an acute care provider and continued treatment with an inhaled glucocorticosteroid-containing regimen after stabilization.[25]

During an exacerbation of chronic obstructive pulmonary disease, shortness of breath is often accompanied by increased cough and sputum production. In this situation, controlled oxygen, bronchodilator therapy, assessment of the need for systemic glucocorticosteroids, antibiotics if necessary, and early use of noninvasive ventilation in acute respiratory failure are important. The Global Initiative for Chronic Obstructive Lung Disease emphasizes that noninvasive ventilation is the standard of care for hospitalized patients with acute respiratory failure. [26]

If dyspnea is associated with acute pulmonary congestion in heart failure, the key factors are unloading, oxygen as indicated, correct body positioning, hemodynamic monitoring, and early diuretic treatment if signs of fluid overload are present. For sustained symptom reduction, subsequent optimization of basic heart failure therapy is also important, but in the emergency phase, stabilization remains the priority. [27]

Table 3. Emergency tactics for the most common acute types of dyspnea

Situation	What is usually required in the first minutes and hours	What is especially important	Sources
Severe, unclear shortness of breath	Saturation monitoring, airway assessment, targeted oxygen therapy, urgent diagnosis of the cause	Do not give oxygen uncontrolled	[28]
Acute asthma attack	Repeated inhalations of a fast-acting bronchodilator, oxygen, systemic glucocorticosteroids, sometimes ipratropium and magnesium	Urgently transfer to the acute unit in case of severe course of the disease	[29]
Exacerbation of chronic obstructive pulmonary disease	Controlled oxygen, bronchodilator therapy, evaluation of systemic glucocorticosteroids and ventilatory support	Non-invasive ventilation is important in respiratory failure.	[30]
Acute congestion in heart failure	Unloading, diuretic therapy for congestion, monitoring, oxygen as indicated	Further optimization of basic cardiac therapy is needed.	[31]
Suspected severe respiratory failure	Urgent hospitalization and escalation of respiratory support	Home treatment is not allowed	[32]

Treatment of shortness of breath in underlying diseases

In asthma, the mainstay of breathlessness control is therapy containing inhaled glucocorticosteroids. The Global Asthma Initiative's 2025 strategy emphasizes that good long-term asthma management relies on regimens containing inhaled glucocorticosteroids, rather than the isolated use of a rapid-acting bronchodilator. If symptoms worsen, a written action plan, timely escalation of therapy, and monitoring of inhalation technique are essential. [33]

In chronic obstructive pulmonary disease, dyspnea reduction is based on long-acting bronchodilators, smoking cessation, vaccination, comorbidity management, and mandatory consideration of pulmonary rehabilitation. The Global Initiative for Chronic Obstructive Lung Disease indicates that in symptomatic patients, the preferred initial pharmacological choice is often a combination of two long-acting bronchodilators, and pulmonary rehabilitation improves exercise tolerance, symptoms, and quality of life regardless of disease severity. [34]

If shortness of breath persists in the setting of chronic obstructive pulmonary disease, it is important not to simply "add more inhalers" but to assess technique, treatment adherence, underlying cardiovascular disease, anxiety, anemia, muscle weakness, and other factors that may exacerbate the symptom. The Global Initiative for Chronic Obstructive Lung Disease specifically emphasizes the need to actively seek and treat comorbid conditions, as they often contribute to disproportionately severe shortness of breath. [35]

In heart failure, the severity of dyspnea decreases primarily when basic cardiac therapy is optimized. Current American and European guidelines on heart failure confirm the central role of the so-called 4 pillars of therapy in heart failure with reduced ejection fraction and emphasize the importance of early initiation and titration of treatment. At the symptom level, this translates into reduced congestion, improved exercise tolerance, and a reduced risk of recurrent decompensations. [36]

For interstitial lung diseases and other chronic diffuse respiratory diseases, medication alone is usually insufficient. American guidelines for pulmonary rehabilitation support its use not only for chronic obstructive pulmonary disease but also for interstitial lung diseases. This is especially important for patients whose shortness of breath limits walking, daily activities, and independence, even after appropriate treatment for the underlying condition has begun. [37]

In obese patients with asthma, symptom management should also be more comprehensive. The Global Asthma Initiative notes that asthma is more difficult to control in obese individuals, and that weight loss of approximately 5-10% can improve disease control. This is a good example of how treating shortness of breath often requires not only medications but also metabolic interventions. [38]

Cause	Basic treatment strategy	What most often reduces shortness of breath?	Sources
Asthma	Inhaled corticosteroids chart, education, and action plan	Inflammation control and proper inhalation therapy	[39]
Chronic obstructive pulmonary disease	Long-acting bronchodilators, smoking cessation, vaccination, rehabilitation	Combination of long-acting drugs and rehabilitation	[40]
Exacerbation of chronic obstructive pulmonary disease	Controlled oxygen, bronchodilator therapy, sometimes systemic glucocorticosteroids and ventilatory support	Rapid correction of respiratory failure	[41]
Heart failure	Optimization of basic cardiac therapy, unloading in case of congestion, rehabilitation	Reducing congestion and early full-fledged therapy	[42]
Interstitial lung diseases	Treatment of the underlying disease, rehabilitation, oxygen according to hypoxemia criteria	Training, education, and correction of hypoxemia	[43]
Asthma in obesity	Basic anti-inflammatory therapy plus weight loss	Improving disease control and respiratory stress	[44]

Non-drug treatment and rehabilitation

One of the most underrated ways to reduce chronic shortness of breath remains rehabilitation. The American Thoracic Society notes that participation in pulmonary rehabilitation programs reduces shortness of breath, increases exercise tolerance, and improves quality of life and emotional well-being in people with chronic respiratory diseases. This is not an "add-on," but a complete treatment component. [45]

Rehabilitation is particularly important in chronic obstructive pulmonary disease. The Global Initiative for Chronic Obstructive Lung Disease emphasizes that pulmonary rehabilitation with training and education improves symptoms and quality of life at any disease severity. Furthermore, after hospitalization for an exacerbation, early initiation of rehabilitation is associated with better outcomes than no such program. [46]

Current guidelines also support graded physical training and multi-component support services for severe chronic respiratory diseases. The idea behind these programs is that they target not only muscle and endurance, but also reduce anxiety, improve symptom control, teach activity tempo, and reduce movement avoidance, which itself exacerbates shortness of breath. [47]

Breathing techniques also play a role. The European Lung Federation, citing the European Respiratory Society's clinical guidelines, notes the benefits of breathing pattern modification techniques, including pursed lip breathing and diaphragmatic breathing. These methods are particularly useful as part of a comprehensive program, rather than as isolated "home remedies." [48]

Even something as simple as directing airflow onto the face from a handheld or tabletop fan is now considered an acceptable and safe measure for reducing shortness of breath in some patients with serious chronic lung diseases. This does not replace treatment of the underlying cause, but it can reduce the subjective severity of the symptom and fits well into a multi-tiered care strategy. [49]

Table 5. Non-drug methods for reducing shortness of breath

Method	What is it used for?	What is known from current recommendations?	Sources
Pulmonary rehabilitation	Reduction of symptoms, increased endurance, improved quality of life	Highly recommended for stable chronic obstructive pulmonary disease and interstitial lung diseases	[50]
Telerehabilitation	Expanding access to rehabilitation	Acceptable as an option along with the full-time program	[51]
Dosed physical training	Reduction of detraining and exertional dyspnea	Supported in symptom control guidelines	[52]
Breathing techniques	Monitoring breathing patterns and subjective discomfort	Can be used during rest and during exercise	[53]
Air flow from the fan	Rapid symptomatic relief	Considered a safe and simple measure in some patients	[54]

Oxygen therapy and treatment of refractory dyspnea

Oxygen therapy does not help every patient with shortness of breath. In acute care, oxygen is needed according to target saturation ranges, not "for comfort." In chronic situations, home oxygen therapy has proven beneficial, particularly in patients with severe chronic hypoxemia. The American Thoracic Society recommends that long-term oxygen therapy for at least 15 hours per day be administered to adults with chronic obstructive pulmonary disease and severe chronic hypoxemia. [55]

In chronic obstructive pulmonary disease, it's important to remember the flip side of the coin. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) recommends that long-term oxygen therapy should not be routinely prescribed for patients with stable disease and moderate desaturation at rest or during exercise. Therefore, shortness of breath alone does not necessarily indicate the need for home oxygen. [56]

When dyspnea remains severe even after optimization of treatment for the underlying disease, it is called a refractory symptom. In such a situation, the most reasonable modern approach is to re-assess whether the underlying cause has been corrected, and whether there is any evidence of anxiety, muscle weakness, deconditioning, improper inhalation technique, latent hypoxemia, or rehabilitation deficiency. Only then should specific symptomatic measures be considered. [57]

For severe chronic respiratory diseases, the European Respiratory Society recommends relying primarily on multi-component care, breathing techniques, exercises, and airflow, rather than routinely prescribing opioids for daily dyspnea. This is an important shift in recent years, distinguishing the current approach from older texts, which often described opioids more broadly. [58]

The situation is different in palliative oncology. The American Society of Clinical Oncology recommends systemic opioids in adult patients with advanced cancer if non-pharmacological measures have failed to provide sufficient relief of dyspnea. Therefore, when writing about the treatment of dyspnea, it is essential to distinguish between chronic respiratory diseases and palliative oncology to avoid conflating these different clinical contexts. [59]

Approach	When appropriate	When should it not be prescribed routinely?	Sources
Controlled oxygen in acute situations	In hypoxemia with a target saturation of 94-98%, or 88-92% if there is a risk of hypercapnia	Not as an uncontrolled high-flow feed to everyone	[60]

Opioids	In palliative oncology, when non-drug measures are ineffective	Not recommended routinely for everyday shortness of breath in severe respiratory diseases	[64]

Monitoring, prevention and re-evaluation

Treatment for dyspnea doesn't end when the patient's breathing improves in the office or emergency room. For lasting results, the underlying cause must be monitored and the symptom reassessed. In asthma and chronic obstructive pulmonary disease, inhalation technique, treatment adherence, and exacerbation frequency must be reviewed, as these are the areas where treatment effectiveness most often becomes lost. [65]

Following a severe exacerbation of chronic obstructive pulmonary disease, early referral to rehabilitation is particularly important. The Global Initiative for Chronic Obstructive Lung Disease indicates that initiating pulmonary rehabilitation during hospitalization or within 4 weeks of discharge is associated with better outcomes than no such intervention. This means that rehabilitation should not be postponed indefinitely. [66]

In patients with asthma, good control reduces the risk of severe attacks and repeated emergency department visits. The Global Asthma Initiative emphasizes the need for a written action plan, early monitoring after an exacerbation, and the avoidance of complete discontinuation of inhaled glucocorticosteroid therapy in adults and adolescents with asthma. [67]

For chronic respiratory diseases, it's helpful not only to reduce the severity of symptoms but also to restore the person's activity. If a patient stops walking, fears exertion, and begins to avoid everyday activities, a vicious cycle of deconditioning develops. Therefore, modern prevention of dyspnea progression includes activity, exercise, effort-saving training, and ongoing self-control support. [68]

A reassessment is especially necessary if shortness of breath changes in nature, becomes nocturnal, occurs at rest, is accompanied by edema, wheezing, chest pain, fainting, or a drop in oxygen saturation. In such a situation, it is impossible to simply intensify the usual treatment. A new diagnosis must be re-evaluated and new cardiac, respiratory, or thromboembolic causes must be excluded. [69]

FAQ

Does shortness of breath always mean lung disease?

No. Dyspnea can be associated not only with the airways and lung tissue, but also with heart failure, hypoxemia, deconditioning, comorbidity, and other physiological mechanisms. This is why there is no universal treatment. [70]

Can shortness of breath be treated with oxygen alone?

No. Oxygen helps with hypoxemia, but it is not a universal remedy for "lack of air." In acute care, it is titrated to target saturation, and at home, it is prescribed mainly for documented severe chronic hypoxemia. [71]

When is urgent help needed?

Urgent care is needed for sudden severe shortness of breath, difficulty breathing at rest, chest pain, cyanosis, confusion, marked drop in oxygen saturation, "numb chest" in asthma, and rapidly worsening symptoms. [72]

Is it possible to use only a rapid-release inhaler if you have asthma?

Modern asthma strategies do not support reliance solely on rapid-acting bronchodilators. Basic therapy should include inhaled glucocorticosteroids in some form or another. [73]

What is the best way to reduce chronic shortness of breath in chronic obstructive pulmonary disease?

Typically, the best effect is achieved through a combination of properly selected, long-acting inhalation therapy, smoking cessation, vaccination, and pulmonary rehabilitation. Drug therapy alone without rehabilitation often produces incomplete results. [74]

Do breathing exercises help?

Yes, but they work best as part of comprehensive care. European respiratory guidelines support breathing techniques and other non-drug approaches for serious chronic lung diseases. [75]

Why do you need a fan if the problem is not heat?

Air flow to the face can reduce the subjective sensation of air shortness in some patients with chronic refractory dyspnea. This is a simple and safe symptomatic measure, although it does not replace treatment of the underlying cause. [76]

When is home oxygen not needed?

It should not be prescribed simply because a person "seems to be having difficulty breathing" unless severe chronic hypoxemia is confirmed. Its routine use is not indicated for moderate desaturations without strict criteria.[77]

Are opioids used for shortness of breath?

It depends on the situation. For severe chronic respiratory diseases, the European Respiratory Society does not recommend the routine use of opioids for everyday dyspnea. However, in palliative oncology, systemic opioids may be appropriate if non-pharmacological treatments have been insufficient. [78]

Why can shortness of breath quickly return after hospital discharge?

Most often, this is due to failure to optimize basic treatment, inhalation technique not being tested, rehabilitation not being initiated, or underlying causes of the symptom remaining unrecognized. Therefore, early monitoring and a recovery program are particularly important after an exacerbation. [79]
