15.3 C.O. Measurement Limitations
The following factors may influence the accuracy of C.O. measurement:
temperature of injectate solution
volume of injectate solution
baseline of patient’s blood temperature
patient’s inspiratory/expiratory cycle
placement of catheter with relation to proximity of lung field
the catheter itself
patient’s heart rate and hemodynamic status
any solution infused with intravenous injection during the C.O. measurement
To obtain accurate C.O. measurements, follow these recommendations:
Temperature of injectate solution must be at least 10 ºC cooler than that of the patient’s blood.
Inject solution at end of expiration.
Inject solution rapidly and smoothly.
Finish injection within four to five seconds.
