Design outcomes

Primary

Measure	Time frame
The relationship between end tidal carbon dioxide and partial pressure of carbon dioxide in blood. After administration of oxygen as 6 liter per min , 5 liter per min and 4 liter per min for 30 mins respectively, make comparison between end tidal and blood carbon dioxide.	—

Secondary

Measure	Time frame
Make comparison of dissociation between end tidal carbon dioxide and partial pressure of carbon dioxide during deep breath in oxygen administration as 6 liter per min, 5 liter per min and 4 liter per min.	—
