Verbal Breathing Coaching to Improve Preoxygenation and Extend Safe Apnea Time in Anesthesia
Sponsor: Prince Sultan Military Medical City
Summary
This study explores whether simply guiding patients to breathe slowly and calmly before anesthesia can help improve oxygen levels and keep them safe for longer during induction. The investigators included 120 participants scheduled for elective surgery, comparing routine preoxygenation with a gentle, coached breathing technique using steady inhalation and exhalation. The investigator focused mainly on how long participants could safely tolerate apnea, while also examining oxygen levels, vital signs, and anxiety.

Verbal Breathing Coaching
In addition to standard preoxygenation, patients receive continuous verbal coaching: "Breathe in slowly through your nose for four seconds" "Now breathe out slowly through your mouth for six seconds" Instructions repeated rhythmically for 3 minutes Delivered by the attending anesthesiologist using a standardized script
