Comparison of Arterial Oxygenation after Preoxygenation with CPAP and without CPAP

K. Chandran, M. Ravikumar

Abstract :

Background and Aims: Preoxygenation and continuous positive airway pressure (CPAP) improve arterial oxygenation. we evaluated the effects of preoxygenation with CPAP or without CPAP by assessing the partial pressure of arterial oxygen (PaO2). Materials and methods: Sixty patients requiring general anaesthesia were randomly divided into two groups. Group A patients (n = 30) were preoxygenated with 100% oxygen at a rate of 10 L/min for 3 min. In Group B (n = 30), 100% oxygen was administered at a rate of 10 L/min for 3 min with CPAP of 10 cm of H2O. PaO2 and PaCO2 were measured before and after the preoxygenation. Results: In our study, there was statistically significant raise of mean PaO2 in CPAP group compared to control group (P < 0.0001). Conclusion: preoxygenation with CPAP improves arterial oxygenation
