What is the first treatment priority for a patient exhibiting respiratory distress of cardiac origin?

In cases of respiratory distress stemming from a cardiac origin, the administration of nitroglycerin is prioritized because it addresses the underlying cardiac condition that is contributing to the respiratory issues. Nitroglycerin works as a vasodilator, helping to reduce the workload on the heart and decrease cardiac oxygen demand. This is particularly important in patients who may be experiencing congestive heart failure, myocardial infarction, or other cardiac-related respiratory distress. By alleviating the strain on the heart, nitroglycerin can improve pulmonary circulation and subsequently improve respiratory function.

While oxygen therapy is critical in managing patients in respiratory distress, it primarily addresses the symptom of hypoxia rather than the cardiac cause of the distress. Continuous positive airway pressure (CPAP) can be beneficial but is generally considered after addressing the cardiac issue directly. Albuterol, a bronchodilator, is typically used for conditions like asthma or COPD but is not the primary treatment for cardiac-related respiratory distress, as it does not target the root cause tied to cardiac function.
