Your acute coronary syndrome patient has a 12-lead indicating an anterolateral wall MI. The patient denies any shortness of breath. The pulse oximeter reading is 89%.
Which of the following is true regarding oxygen administration?
- Oxygen is not necessary as the patient denies any shortness of breath.
- Oxygen should be administered at 12-15 liters per minute to increase the pulse oximeter to 100%.
- Oxygen should be provided at 4 liters per minute via nasal cannula to avoid constricting the coronary arteries.
- Oxygen should be started at 6 liters per minute via nasal cannula to decrease anxiety yet increase the pulse oximeter reading.
