18.3 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

■ Temperature of injectate solution must be at least 10 ºC cooler than that of the patient’s blood.
■ Inject solution at end of expiration.
