Comparison of the Efficiency of Mouth-to-nose Breathing With Mouth-to-mouth Breathing
The purpose of this study is to find out the best way of providing artificial breathing during cardiopulmonary resuscitation (CPR). Current standard CPR involves giving mouth-to-mouth breathing to people requiring CPR. The rescuer pinches the person's nostrils closed and breathes into the mouth of the unconscious person with his or her own mouth.
Some CPR studies have shown that it might be easier and more effective to breathe air into a person's nose instead of the mouth. People receiving CPR often have blocked airways, so breathing into the mouth does not always work.
We think mouth-to-nose breathing may be more efficient and easier to do. In this case, the rescuer closes the person's mouth by pushing the jaw up and holding it still. Then the rescuer breathes into the unconscious person's nose by covering the nose entirely with his or her mouth. We are doing this study to try to find out which way works better.
We will perform both ways of breathing on people who are unconscious (asleep) before planned (non-emergency) surgery and compare their effectiveness.

- Comparing CO2 elimination with mouth-to-nose versus mouth-to-mouth breathing in non-paralyzed adult patients under general anesthesia. [ Time Frame: 1.5 years ]
|Study Start Date:||March 2008|
|Study Completion Date:||January 2010|
|Primary Completion Date:||January 2010 (Final data collection date for primary outcome measure)|
Twenty healthy subjects between 18 to 59 years of age meeting ASA I-II criteria, undergoing elective surgery, requiring general anesthesia and being able to breathe through both their nose and mouth.
Other: Mouth-to-mouth or mouth-to-nose breathing
Patients undergoing elective surgery under general anesthesia will be given mouth-to-mouth and mouth-to-nose breaths. The respiration process will be measured and recorded by the help of elastic bands put around the chest and abdomen. The efficiency of the breathing methods will be evaluated.
