15.3 Influencing Factors
The factors that affect cardiac output are:
„ temperature of injectate solution,
„ volume of injectate solution,
„ patient’s baseline blood temperature,
„ patient’s inspiratory/expiratory cycle,
„ The degree of the catheter’s distal end in close proximity to the lung,
„ the catheter itself,
„ the patient rhythm and hemodynamic status, and
„ any other rapid IV solutions which are infused while the C.O. measurement is being
performed.
Followings are some technique suggestions to obtain accurate C.O.:
„ Injectate solution must be cooler than the patient’s blood.
„ Inject solution rapidly and smoothly.
„
Inject at end expiration.
„ Wait 1 minute between injections to allow baseline to become stabilized.
