A 56-year-old male with a significant cardiac history complains of sudden onset shortness of breath. He is alert, anxious and showing signs of orthopnea. Vital signs are BP 162/100, pulse matches ECG below, respirations 22 with crackles. What should you do?

For acute cardiogenic pulmonary edema, continuous positive airway pressure (CPAP) is the priority because it rapidly improves oxygenation and reduces the work of breathing while unloading the heart. The positive pressure opens collapsed alveoli, increasing oxygen exchange, and also decreases the heart’s workload by reducing preload (venous return) and afterload. This helps push fluid out of the lungs and relieves crackles and dyspnea, fitting this patient’s orthopnea, anxiousness, crackles, and elevated blood pressure. Oxygen by a nonrebreather mask can help, but CPAP provides superior support in pulmonary edema by both improving oxygenation and addressing the hemodynamics of the failing heart. Simply positioning upright and monitoring is beneficial but insufficient on its own. Nitroglycerin can be considered in some cases, but it does not address the alveolar edema as effectively as CPAP does in this scenario and may worsen hypotension if not carefully monitored.
