Table 1. Transthoracic cardiac POCUS views, probe position, and assessment.

POCUS: point-of-care ultrasound; EF, ejection fraction; RV, right ventricle.

VIEW	PROBE POSITION	ASSESSMENT
Parasternal long-axis	Probe at 3rd- 4th intercostal space with indicator directed to 10 o’clock position	Assesses EF, ventricular size, mitral valve, aortic stenosis or regurgitation, hypertrophic obstructive cardiomyopathy, and congestive heart failure
Parasternal short-axis	Probe at 3rd- 4th intercostal space with indicator directed to 2 o’clock position	Assesses volume status, RV volume overload, coronary ischemia
Apical four chamber	Probe at 6th midclavicular line intercostal space with indicator directed to 3 o’clock position	Assesses valvular function, atrial sizes, ventricular sizes, systolic function
Subcostal four chamber	Probe at subxiphoid space with indicator directed to 3 o’clock position	Assesses pericardial effusions, RV, tricuspid valve
