In an emergency room, a patient is found to have a depressed breathing rate, and subsequently low oxygen levels in the tissues. He is put on oxygen, but his respiration rate continues to be too low, and his oxygen saturation level in his tissues also continues to be too low. Will increasing the oxygen levels that he is receiving correct his low breathing rate?
A. Yes, because normal oxygen levels in the tissues will cause his breathing rate to return to normal.
B. Yes, because the increased oxygen levels in the lungs will stimulate the breathing rate to return to normal.
C. No, because the oxygen will be immediately used up to the previous deficit.
D. No, because the brain does not use oxygen levels to regulate breathing.
D. No, because the brain does not use oxygen levels to regulate breathing.
