SIMPLE approach for evaluation of key elements during focused cardiac ultrasound sound (FoCUS) in shock patients

SIMPLE approach in focused cardiac ultrasound
S	Chamber size and shape, particularly LV and RV size
I	IVC size and collapsibility IVS movement Intimal flaps inside the aorta, suggestive of aortic dissection
M	Mass in the heart chambers (commonly intramural clots and atrial myxoma) Myocardium (motion and thickness)
P	Pericardial effusion Pleural effusion
L	Left ventricular systolic function
E	Abdominal aorta in the epigastrium
