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:
““Never hug and kiss your children! Mother love may make your children’s infancy unhappy and prevent them from pursuing a career or getting married!” That’s total hogwash, of course. But it shows on extreme example of what state-of-the-art “scientific” parenting was supposed to be in early twentieth-century America. After all, that was the heyday of efficiency experts, time-and-motion studies, and the like.”
—Lawrence Kutner (20th century)
“My mouth blooms like a cut.”
—Anne Sexton (1928–1974)
“God bless the physician who warms the speculum or holds your hand and looks into your eyes. Perhaps one subtext of the health care debate is a yen to be treated like a whole person, not just an eye, an ear, a nose or a throat. A yen to be human again, on the part of patient and doctor alike.”
—Anna Quindlen (b. 1952)
