Abstract An oxygen deficiency exists when the concentration of oxygen, by volume, drops to a level at which atmosphere supplying respiratory protection must be provided. How should the initial minute ventilation setting be adjusted for an adult patient with a body temperature of 40 C?Increase it by 30% because the minute ventilation would have to be increased by 10% for each degree above 37 C. 52.
