Dyspnea
Dyspnea is a subjective feeling of shortness of breath. Dyspnea may be observed, for instance in a person noticeably struggling to breath. However, it is primarily the patients subjective experience that the clinician must assess. A description of dyspnea may include: I feel like Im suffocating or my chest feels tight or I cant seem to get enough air.
Common reasons for experiencing dyspnea include lung disease and heart disease. Dyspnea is also a common symptom during the dying process. The onset of dyspnea is generally a progressive occurrence; therefore, a sudden onset should be considered a medical emergency.
- Assessment Dyspnea can be subjectively assessed, like all symptoms, by using the PQRSTU mnemonic (see Symptom Assessment) or other numeric scales such as the ESAS (see Symptom Assessment). Objective clinical assessment should be based on diagnosis. For instance, a person with a history of lung disease will require a thorough lung exam. The patient may also benefit from pulse oximetry and chest x-ray among other diagnostics, depending on patient-centered goals.
- Treatment Primary treatment of dyspnea is generally focused on the underlying medical cause. For instance, a person experiencing dyspnea secondary to decompensated heart failure should be treated with a diuretic if possible. Non-pharmacologic treatment can include teaching pursed lip breathing, opening a window or providing a fan to increase air movement across the face, or oxygen. While many patients and their caregivers may ask for supplemental oxygen in the treatment of dyspnea, it has only been found efficacious in patients who are hypoxic. For those whose symptoms are refractory to standard care, such as a diuretic or nonpharmacologic management, opiates are the most common treatment. A referral to palliative care may be helpful to manage treatment at this time.
People with any type of lung disease may experience anxiety as dyspnea occurs or even in anticipation of dyspnea. Therefore, anxiolytics such as benzodiazepines are often used. Antidepressants have also been found to be helpful for those with frequent debilitating anxiety. Consult an evidence-based guideline for further information in the palliative treatment of dyspnea.
