FoCUS consists of 4 basic views of the heart namely parasternal long- and short-axis views, the apical 4-chamber view, and the subxiphoid view, as described in the Rapid Ultrasound in Shock ( RUSH) protocol (Figure 1). The parasternal views are obtained with the probe positioned just left of the sternum at intercostal space 3 or 4 Parasternal Long Axis Views (2 of 4) In this view, the left ventricle, mitral valve and aortic valve are in long axis. The probe may need to be angulated from it's original placement to properly align the beam to visualize a left ventricular inflow-outflow view. In some cases the aortic root and the ascending aorta maximal diameter are out of. Parasternal short axis; view the transducer is applied to a similar position on the precordium as used for the long axis view. However, the transducer marker points between the 12 o'clock position and the patient's left shoulder. This corresponds to approximately 90 degrees of rotation.
