No results posted yet for this study

Summary

Atelectasis after induction of general anesthesia is common even in healthy patients and is clinically problematic, especially in obese patients. We aim to investigate whether preoxygenation with high-flow nasal oxygen during anesthesia induction reduces atelectasis in obese patients.

Conditions

  • Anesthesia, General
  • Pulmonary Atelectasis

Interventions

OTHER

high-flow nasal oxygen

preoxygenation using high-flow nasal oxygen, FiO2 1.0, 40 L/min, 3 min

OTHER

facemask

preoxygenation using facemask, FIO2 1.0, fresh gas flow 10 L/min, 3 min
