Photoacoustic Spectroscopy with Quantum Cascade Lasers for Trace Gas Detection

Various applications, such as pollution monitoring, toxic-gas detection, non invasive medical diagnostics and industrial process control, require sensitive and selective detection of gas traces with concentrations in the parts in 10 (ppb) and sub-ppb range. The recent development of quantum-cascade lasers (QCLs) has given a new aspect to infrared laser-based trace gas sensors. In particular, si...

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...

The effects of continuous blood gas monitoring during cardiopulmonary bypass: a prospective, randomized study--Part II.

The impact of blood gas management during cardiopulmonary bypass (CPB) on patient care has not been examined and remains controversial. The purpose of this study was to determine whether precise blood gas management during CPB influences patient outcome. Fifty-nine patients were enrolled in an Institutional Review Board-approved, prospective, randomized study. An in-line blood gas monitor (CDI ...
