Overview
The monitor uses thermodilution to measure the blood flow pumped by the heart. A
solution of known temperature and volume is injected into the blood stream in the
right atrium. The injectate mixes with and cools the surrounding blood. The blood
temperature reaches its minimum relatively quickly and then warms up slowly until it
returns to the blood temperature baseline. The total drop in the patient’s blood
temperature is inversely related to the patient’s cardiac output: the lower the cardiac
output, the more the injectate cools the blood down, and vice versa. A thermistor in
the catheter tip continuously measures the temperature of the blood as it leaves the
heart.
The monitor restores C.O. settings to their default values when you discharge a patient
or select
New Patient
after turning on the monitor. If you subsequently press the
C.O.
Start
fixed key (or if you press
C.O. Start
after a catheter is disconnected), the
monitor displays the C.O. setup menu, sounds a tone, and requests that you confirm
the current setup data. Press the
C.O. Start
fixed key within 30 seconds to confirm the
current setup data, display the C.O. Averaging screen and begin measuring cardiac
output.
Blood flow is measured in liters per minute. In computing cardiac output, the monitor
takes the following factors into account:
Injectate volume, temperature, density, and specific heat
Blood baseline temperature, density, and specific heat
Temperature changes of the blood-injectate mixture
