A 71-year-old female presents with dyspnea and wheezing of unknown origin. After treating the hypoxia, what is the next best step in management?

After correcting the low oxygen, the priority is to figure out what is causing the dyspnea and wheezing. Many different conditions can present with these symptoms in an elderly patient—heart failure with pulmonary edema, COPD or asthma flare, pneumonia, pulmonary embolism, or even an anaphylactic reaction. Without knowing the exact cause, starting targeted therapy (like epinephrine, CPAP, or steroids) may be inappropriate or even harmful. To uncover the etiology, gather focused information and perform targeted testing: obtain a quick history (onset and progression of symptoms, exposures, prior lung or heart disease, meds), complete a focused exam, and monitor vitals and oxygenation. Diagnostics help differentiate cardiogenic from noncardiogenic processes and guide treatment. This typically includes chest imaging (to look for edema, infection, or consolidation), an ECG, and labs such as BNP, troponin, CBC, electrolytes, and possibly arterial blood gas. Based on the resulting data, you can tailor therapy to the underlying problem rather than applying a broad treatment approach.
