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.

“For who would bare the whips and scorns of time,
Th’oppressor’s wrong, the proud man’s contumely,
The pangs of disprized love, the law’s delay,
The insolence of office, and the spurns
That patient merit of th’unworthy takes,
When he himself might his quietus make
With a bare bodkin?”
