A 60s year old patient arrives with acute onset dyspnea. No chest pain or leg swelling. Vital signs revealed a blood pressure of 115/70 mm Hg, heart rate of 130 beats/min, respiratory rate of 18 breaths/min, and O2 saturation of 92%, improving to 99–100% with nasal cannula and non-rebreather oxygen at flush rate (>40 L/min).
Cardiac POCUS shows a hyperechoic clot in transit bouncing in the right atrium and moving through the tricuspid valve into the right ventricle (clip 1), confirming the diagnosis of pulmonary embolism.
POCUS Pearl: The above image obtained early on during patient presentation guided patient management. There is no rule that says POCUS need wait until after labs result, other imaging obtained etc. Read more about how POCUS was utilized in this case of undifferentiated dyspnea [https://doi.org/10.1016/j.jemermed.2021.01.035]
