Safe Use of CPAP and PEEP During Induction of General Anesthesia
The study compares the safety of using pressure controlled ventilation with a positive end-expiratory pressure (PEEP) during induction of general anaesthesia immediately after apnoea to a standard method starting ventilation…

Safe Time for Apnea After Preoxygenation
The use of 100% oxygen during the induction of general anesthesia is always preferable to have enough time to secure the airway by endotracheal intubation, because preoxygenation with a low oxygen concentration may reduce the…
