Answer:
He can deduce that The pO2 of her cells is less than or equal to 200 mmHg.
Explanation:
Partial pressure of oxygen(pO2) measures the amount of gaseous oxygen dissolved in the blood. It purposes to measure the effectiveness of the lungs in pulling oxygen from the atmosphere to the lungs.
In the incubator where the gases levels are carefully regulated, a pO2 of 200mmHg on the incubator deduces that the pO2 of her cells is equal or less than 200mmHg.
