Oxygenator exhaust capnography for prediction of arterial carbon dioxide tension during hypothermic cardiopulmonary bypass.
Continuous monitoring and control of arterial carbon dioxide tension (P(a)CO2) during cardiopulmonary bypass (CPB) is essential. A reliable, accurate, and inexpensive system is not currently available. This study was undertaken to assess whether the continuous monitoring of oxygenator exhaust carbon dioxide tension (PexCO2) can be used to reflect P(a)CO2 during CPB. A total of 33 patients under...
متن کاملMembrane oxygenator exhaust capnography for continuously estimating arterial carbon dioxide tension during cardiopulmonary bypass.
Typically, the standard practice for measuring the arterial blood carbon dioxide tension (PaCO2) during cardiopulmonary bypass (CPB) is to take intermittent blood samples for analysis by a bench blood gas analyzer. Continuous inline blood gas monitors are available but are expensive. A potential solution is the capnograph, which was evaluated by determining how accurately the carbon dioxide ten...
متن کاملChanges in arterial blood PO2, PCO2, and pH during deep hypothermic circulatory arrest in adults.
Safe limits of time and temperature during sleep hypothermic circulatory arrest (DHCA) still remain controversial. Furthermore, continuous changes of PaO2, PaCO2, and pH have never been measured during DHCA in humans. Continuous intraarterial blood gas (CIABG) monitoring is a new technology allowing us to study chronological changes occurring due to metabolism during DHCA. When the patients' te...
متن کاملArterial Pco2 and Cerebral Hemodynamics.
REIVICH, MARTIN. Arterial Pcoz and cerebral hemodynamics. Am. J. Physiol. 206(1) : q-35. rg64.---The effect of arterial Pco:! in the control of cerebral hemodynamics over the full range of responsiveness of the cerebral vasculature was studied in the rhesus monkey. Cerebral perfusion pressure and arterial 02 saturation were controlled so that they produced no significant effect on the cerebral ...
متن کاملCerebral Artery During Nonpulsatile Hypothermic Cardiopulmonary Bypass
Background and Purpose We evaluated the utility of blood flow velocity measurements by transcranial Doppler ultrasonography as a tool to indirectly measure cerebral perfusion during cardiopulmonary bypass. Methods We simultaneously measured blood flow velocity in the middle cerebral artery and physiological variables in 18 patients undergoing cardiac surgery under hypothermic cardiopulmonary by...
