Explanation of ICO (Optional)
(1) ICO Measurement
Heart (Left or Right Ventricular) for 1 minute to export this amount of
blood "CO - Cardiac output" is called.
CO units of L / min is.
As a time of ventricular contraction is the release of blood, the amount
of SV (Stroke Volume) is called,
The formula CO = SV x HR will be established.
Thermodilution measurement of the use of ICO, and is measured by
calculating the following:
CO = V x (TB - TI) x (SI x CI) x 60 x CT x K
A (SB x CB) 1
WHERE:
CO = cardiac output
V = volume of injectate (ml)
A = area of thermodilution curve in square mm divided by paper speed (mm/sec)
K = calibration constant in mm/ °C
TB, TI = temperature of blood (B) and injectate (I)
SB, SI = specific gravity of blood and injectate
CB, CI = specific heat of blood and injectate
(SI x CI ) = 1.08 when 5% dextrose is used
(SB x CB)
60 = 60 sec/min
CT = correction factor for injectate warming
