• Conditions: Medical and Surgical,

• Registration Number: CTRI/2020/03/023753
• Lead Sponsor: Department of AnaesthesiologyNDMC Medical College and Hindu Rao Hospital

Brief Summary

Nasal prongs will be applied to evaluate it’s effectiveness in maintaining blood oxygen saturation in case of a extended apnoea due to a difficult airway which will be simulated by application of Manual In Line Stabilization of cervical spine.

Primary Outcome Measures

Name	Time	Method
Wether nasal prongs are effective in maintaining oxygen saturation during periods of apnea in patients with simulated cervical spine immobilisation	6 minutes or untill the saturation falls till 95%

Secondary Outcome Measures

Name	Time	Method
To compare the safe apnoea time in group which will be only preoxygenated as compared to group receiving oxygen insufflation through nasal prongs during apneoa in addition to preoxygenation.	6 minutes or until the saturation falls to 95%
