to alert the health care team to impending
cardiovascular crisis before organ injury
ensues; it is routinely used in this manner in
the operating room during high-risk surgery.
to obtain information specific to the disease
processes, which may facilitate diagnosis andtreatment and allow one to monitor the
response to therapy.

- have traditionally involved use of thepulmonary artery catheter (PAC),
which was originally designed formeasurement of pulmonary arteryand wedge pressures
- invasive catheters are typically usedto measure and monitor variouspressures and cardiac output

Cardiac output
- is the heart rate times the stroke
volume and is the amount of blood
pumped by the ventricles each minute.

Heart rate is the number of heartbeats perunit of time - typically expressed as beats per
minute (bpm) - which can vary as the body's
need for oxygen changes, such as during
exercise or sleep.
Stroke volume is the amount of blood ejected
with each cardiac contraction/heart beat

Cardiac index
- is the cardiac output adjusted tobody size and is a better parameter
to use than the cardiac output

Clinicians must keep in mind that the
monitor and its information do not
replace clinical judgement or necessarily
imply quality patient care.
