Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Preoxygenation via THRIVE/High Flow Nasal Cannula
Patients receive preoxygenation for induction of general anaesthesia via High Flow Nasal Cannula for the duration of 5 minutes. After that the induction agents will be given. Now arterial blood gases will be drawn every 2 minutes and the SpO2 will be measured until the 6th apnoeic ABG or if the SpO2 decreases to 92%. After that normal intubation follows.
Preoxygenation with High Flow Nasal Cannula
Preoxygenation for 5 minutes via High Flow Nasal Cannula. After induction of anaesthesia apnoeic oxygenation with HFNC
Preoxygenation via face mask (PROX)
Patients receive preoxygenation for induction of general anaesthesia via tight fitting face mask for the duration of 5 minutes. After that the induction agents will be given. Now arterial blood gases will be drawn every 2 minutes and the SpO2 will be measured until the 6th apnoeic ABG or if the SpO2 decreases to 92%. After that normal intubation follows.
