Look for obvious pathology
Assess wall thickness + chamber dimensions
Assess bi - ventricular function
Image pleura on both sides
Relate the information to the clinical context
Apply additional ultrasound

The global function of the heart is determined by the interaction between:
Right ventricle

Preload
Afterload
Contractility
Heart rate

Hemodynamic instability, perform a systematic evaluation of these determinants plus concomitant pathology:
(e.g. pericardial effusion, pulmonary embolus, pleural effusion, pneumothorax, valvulopathy, dissection, defects)

PATHOLOGY TO BE CONSIDERED IN PARTICULAR:
• Post OP cardiac surgery, following cardiac catheterisation, trauma, renal failure, infection.
• Pulmonary embolus, RV infarction, pulmonary hypertension, volume overload.
• Ischemic heart disease, dilated cardiomyopathy, sepsis, volume overload, aorta insufficiency.
• Aorta stenosis, arterial hypertension, LV outflow tract obstruction,
hypertrophic cardiomyopaty, myocardial deposit diseases.
