RANSCUTANEOUS BLOOD GAS MONITORING
Overview
With transcutaneous blood gas monitoring, you can perform continuous non-invasive
measurements of the body’s ability to deliver oxygen to tissue and remove carbon
dioxide via the cardiopulmonary system. The ability to obtain pre-ductal and
postductal tpO

values for neonates may indicate right to left shunting.
Transcutaneous monitoring is useful in trending the patient’s oxygenation status and
can reduce the number of blood gas samples needed. However, it is not intended to
replace invasive blood gas monitoring via a blood gas device. Blood gas values do not
match transcutaneous gas readings.
NOTE:
Transcutaneous blood gas measurements are contraindicated for an infant
patient under gas anesthesia. Anesthetic agents, such as halothane, can cause
incorrect or drifting readings.
Noninvasive trending of transcutaneous carbon dioxide partial pressure is
intended for any patient population.
Transcutaneous blood gas values may not be clinically useful for patients with
reduced cardiac output.
