User :   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.
Doctor :   Hi
User :   hello there
Doctor :   Let me explain it to you.
Doctor :   The respiration is controlled by carbodioxide and not the levels of oxygen.
User :   ok
Doctor :   If oxygen is supplemented the carbodioxide levels may get suppressed and cause reduction in the respiratory drive and further worsening of the situation,
User :   that makes sense
Doctor :   This could have caused respiratory arrest.
Doctor :   Have you followed what I said.
