No results posted yet for this study

Summary

The objective of this study is to compare the effects of manual ventilation and AutoFlow ventilation, administered during the induction of general anesthesia, on cerebral (s-rSO₂) and peripheral (somatic) oxygenation (p-rSO₂) in geriatric patients.

Conditions

  • Cerebral Oxygenation
  • Peripheral Oxygenation
  • Geriatrics
  • Ventilation
  • Near-Infrared Spectroscopy

Interventions

PROCEDURE

Manual Mask Ventilation

Patients will receive manual mask ventilation with 100% oxygen using a reservoir bag. This procedure will be performed by an experienced anesthesiologist or anesthesia resident for 2 minutes following the administration of induction agents, allowing for adequate muscle relaxation prior to endotracheal intubation.

PROCEDURE

AutoFlow Mechanical Mask Ventilation

Patients will receive mask ventilation delivered mechanically by the anesthesia workstation. The device will provide 100% oxygen for 2 minutes following the administration of induction agents. The ventilator settings will be standardized to an AutoFlow mode with a tidal volume (VT) of 6 mL/kg (based on ideal body weight), a respiratory rate of 12 breaths/minute, a peak pressure limit of 30 cmH₂O, and a Positive End-Expiratory Pressure (PEEP) of 5 cmH₂O
