We all see that oxygen/ artificial breathing is done to a patient, the gas/air is sent through water so that it carries some moisture with it.
- This is done to ensure that the mucous layer in the wind pipe doesn't dry up.

People use oxygen mask but why does it have holes....when tubes are used to send the oxygen clearly the tube doesn't close the total hole.... ever wondered why???
- Pure oxygen is dangerous. Patients are given in air with enriched oxygen.
I thought they are there to remove the exhaled air out!
