简要总结
Preoxygenation is a method of enriching blood with 100% oxygen inhalation for 3min before induction of general anaesthesia to prevent patient from hypoxia during intubation. Obese patients are more susceptible to hypoxia due decrease functional residual capacity. Preoxygenating obese patients with pressure support ventilation may help in prolongation of safe apnea time. We want to study effect of pressure support ventilation on preoxygenation is it shortens preoxygenation time, prolong safe apnea time, as it will be useful in emergency intubation and difficult intubation
