Enrollment

106 participants

Start Date

May 13, 2026

Study Type

INTERVENTIONAL

Conditions

Ventilation Cerebral Oxygenation Geriatrics Near-Infrared Spectroscopy Peripheral Oxygenation

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.

Eligibility

Min Age: 65 Years

Plain Language Summary

Simplified for easier understanding

This clinical trial is studying a procedure called AutoFlow Mechanical Mask Ventilation and a procedure called Manual Mask Ventilation for people with cerebral oxygenation, geriatrics, and other related conditions. The study is currently recruiting participants at 1 location. People eligible for this study include aged 65 Years and older.

This summary was AI-generated to explain the trial in plain language. It is not medical advice. Always discuss eligibility with your doctor before enrolling in a clinical trial.

Interventions

PROCEDUREManual 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.

PROCEDUREAutoFlow 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
