The usefulness of end-tidal carbon dioxide monitoring during apnea test in brain-dead patients

The usefulness of end-tidal carbon dioxide monitoring during apnea test in brain-dead patients

BACKGROUND The apnea test (AT) is essential to confirming the diagnosis of brain death, but critical complications can occur if the AT is maintained over a long period. To minimize the AT period, we used end-tidal carbon dioxide (ETCO2) monitoring because ETCO2 is closely correlated with partial pressure of arterial carbon dioxide (PaCO2). The aim of the present study is to evaluate the usefuln...

End-tidal carbon dioxide monitoring.

An evaluation of transcutaneous carbon dioxide partial pressure monitoring during apnea testing in brain-dead patients.

BACKGROUND Diagnosis of brain death usually requires an arterial carbon dioxide partial pressure (Paco2) of 60 mmHg during the apnea test, but the increase in Paco2 is unpredictable. The authors evaluated whether transcutaneous carbon dioxide partial pressure (Ptcco2) monitoring during apnea test can predict that a Paco2 of 60 mmHg has been reached. METHODS The authors compared Ptcco2 measure...

Monitoring of end tidal carbon dioxide and transcutaneous carbon dioxide during neonatal transport.

OBJECTIVE To assess the accuracy of measurements of end tidal carbon dioxide (CO2) during neonatal transport compared with arterial and transcutaneous measurements. DESIGN Paired end tidal and transcutaneous CO2 recordings were taken frequently during road transport of 21 ventilated neonates. The first paired CO2 values were compared with an arterial blood gas. The differences between arteria...
