Clinical Trial Summary

This study aims to determine the duration for pre-oxygenation using THRIVE and facemask for parturients.

Description:

We aim to determine the duration required for THRIVE and facemask preoxygenation in parturients for them to achieve ETO2 >90%.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Preoxygenation Duration	Duration to achieve EtO2 >=90% after tidal volume breathing using THRIVE and facemask pre-oxygenation.	Maximum 8 minutes
Secondary	Proportion to Reach End Tidal Oxygen (ETO2) of 90 Percent at 3 Minutes		3 minutes of pre-oxygenation
Secondary	Proportion to Reach EtO2 of 90 Percent at 4 Minutes		4 minutes of preoxygenation
Secondary	Proportion to Reach EtO2 of 90 Percent at 5 Minutes		5 minutes of preoxygenation
Secondary	Proportion to Reach EtO2 of 90 Percent at 6 Minutes		6 minutes of preoxygenation
Secondary	Proportion to Reach EtO2 of 90 Percent at 7 Minutes		7 minutes of preoxygenation
Secondary	Proportion to Reach EtO2 of 90 Percent at 8 Minutes		8 minutes of preoxygenation
Secondary	Comfort Score	Patients were asked to rate their comfort with the device on a 5 point Likert Scale: (1=completely uncomfortable, 2=slightly uncomfortable, 3=neutral, 4=slightly comfortable, 5= completely comfortable)	1 minute after data collection
Secondary	Acceptability Score	Acceptability was measured with a 5-point Likert Score (1= unacceptable, 2=slightly unacceptable,3=neutral, 4=slightly acceptable, 5=acceptable).	1 minute after data collection
