In consequence I began privately to consider that it had a movement as it were in a circle . . . by calculating the amount of blood transmitted at each heartbeat and by making a count of the beats let us convince ourselves that the whole amount of the blood mass goes through the heart from the veins to the arteries and similarly makes the pulmonary transit.

Overview In critical care the goals of hemodynamic monitoring include mainly detection of cardiovascular insufficiency and diagnosis of the underlying pathophysiology. At the bedside clinicians are faced with the challenge of translating concepts such as preload contractility and afterload into determinants of stroke volume and hence cardiac output. Ultrasound and echocardiography offer unique insight into ventricular filling and systolic function. In recent years there has been a general trend away from invasive hemodynamic monitoring. This was initially motivated by published data suggesting an association between the pulmonary artery catheter PAC and excess mortality in critically ill Despite specific risks subsequent randomized controlled trials have not sustained the concerns about excess The PAC should not be regarded as obsolete. As already discussed in this text ultrasound is proving useful in guiding safe and timely placement of many components of hemodynamic monitoring systems including arterial peripheral and central venous access devices. Furthermore because of its real-time nature ultrasound including echocardiography offers the
