An accident to the head can affect the ability of a person to ventilate ( breathe in and out) and so can drugs
a. What would happen to the partial pressures of oxygen and carbon dioxide in the blood if a person cannot properly ventilate?
b. When a person with hypoventilation is placed on a ventilator, an air mixture is delivered at pressures that are alternately above the air pressure in the person’s lung, and then below. How will this move oxygen gas into the lungs and carbon dioxide out?

a) The O2 level will fall, CO2 level will rise.
b) It comes back to partial pressure again. When you put the air in, the ppO2 is about 0.2 bar (20% oxygen). In the body, it will be lower, so the body will absorb oxygen. There is no measurable CO2 in air, but in the body it will be greater than 0.04bar, so CO2 will come out on the exhalation.
