The two major forms of disordered lung mechanics that result in pulmonary dyspnea are obstructive lung diseases, causing increased airway resistance, and restrictive lung diseases, causing increased lung stiffness. [The role of the echo-dipyridamole test in the differential diagnosis of chest pain]. In respiratory arrest, there is still blood flow and a pulse for the first few minutes. This process is experimental and the keywords may be updated as the learning algorithm improves.

The physiology of normal respiration and gas exchange is complex, and that of dyspnea is even more so. Does this dyspneic patient in the emergency department have congestive heart failure? It often has multiple etiologies. PubMed This disruption in blood flow leads to increased blood pressure in the blood vessels of the lungs, which causes leakage and accumulation of fluid. Further testing is individualized. The most common obstructive causes are chronic obstructive pulmonary disease (COPD) and asthma. Subsequently, clinical data were correlated with BNP values, which proved not to improve the discrimination between cardiac or respiratory etiology of dyspnea.

Is my breathing trouble keeping me awake. The carotid and aortic bodies and central chemoreceptors respond to the partial pressure of oxygen (PO2), partial pressure of carbon dioxide (PCO2) and pH of the blood and cerebrospinal fluid.2 When stimulated, these receptors cause changes in the rate of ventilation. The emergency clinician must provide appropriate initial treatment for a potentially life-threatening illness while working through a wide differential diagnosis. Pleuritic chest pain is caused by inflammation of the parietal pleura and can be triggered by a variety of causes. It's caused by a buildup of fluid in the lungs due to .

The central nervous system, in response to anxiety, can also increase the respiratory rate.3 In a patient who experiences hyperventilation, subsequent correction of the decreased PCO2 alone may not alleviate the sensation of breathlessness. Auscultation of the lungs provides information regarding the character and symmetry of breath sounds such as rales, rhonchi, dullness or wheezing.
