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)
“As long as the “woman’s work” that some men do is socially devalued, as long as it is defined as woman’s work, as long as it’s tacked onto a “regular” work day, men who share it are likely to develop the same jagged mouth and frazzled hair as the coffee-mug mom. The image of the new man is like the image of the supermom: it obscures the strain.”
—Arlie Hochschild (20th century)
“Narcissist: psychoanalytic term for the person who loves himself more than his analyst; considered to be the manifestation of a dire mental disease whose successful treatment depends on the patient learning to love the analyst more and himself less.”
—Thomas Szasz (b. 1920)
