Efficiency of Mouth To Patient Insufflation
Normal atmospheric air contains approximately 21% oxygen when created in. After gaseous exchange has taken place in the lungs, with waste products (notably carbon dioxide) moved from the bloodstream to the lungs, the air being exhaled by humans normally contains around 17% oxygen. This means that the human body utilises only around 19% of the oxygen inhaled, leaving over 80% of the oxygen available in the exhalatory breath.
This means that there is more than enough residual oxygen to be used in the lungs of the patient, which then crosses the cell membrane to form oxyhemoglobin.

Famous quotes containing the words efficiency, mouth and/or patient:
“Nothing comes to pass in nature, which can be set down to a flaw therein; for nature is always the same and everywhere one and the same in her efficiency and power of action; that is, nature’s laws and ordinances whereby all things come to pass and change from one form to another, are everywhere and always; so that there should be one and the same method of understanding the nature of all things whatsoever, namely, through nature’s universal laws and rules.”
—Baruch (Benedict)
“With torn and bleeding hearts we smile,
And mouth with myriad subtleties.”
—Paul Laurence Dunbar (1872–1906)
“Our challenge as parents is to be patient enough to allow our children to take ten minutes to do something that would take us two seconds. We need to allow our children to develop what I call their “struggle muscle.” This is developed the same way any other muscle develops, through regular exercise.”
—Stephanie Martson (20th century)
