When a pulmonary embolism is large enough to obstruct flow, the right ventricle strains against the resistance — and its response is measurable at the bedside with POCUS. In general, the findings are specific but not sensitive. Therefore, their absence does not rule out PE, but their presence is highly informative. The right ventricle is normally smaller than the left in every cardiac view. RV dilation suggests elevated pulmonary pressures from PE, pulmonary arterial hypertension, or chronic...
