Physiology Question:

Explain if a patient was admitted to the hospital with chronic obstructive pulmonary disease. His PO2 was 55 and PCO2 was 65. A new resident orders 54% oxygen via the venturi mask. One hour later, after the oxygen was placed, the nurse finds the patient with no respiration or pulse. She calls for a Code Blue and begins CPR. Explain why the patient stopped breathing.?


Oxygen should have been given and has been rightly done. The cause of cessation of breathing could be due to a myocardial infection, respiratory arrest, cardiac arrest and many other causes. Nothing can be said about it without investigative reports.
