Your patient with emphysema is receiving oxygen. What flow rate would you not want to exceed for this patient?

1 L/min
2 L/min
6 L/min
10 L/min

Explanation

Answer: B - The oxygen level for an emphysema patient should not exceed 2 L/min. The patient has been in a long-standing hypercapnia, which leads to the patient’s drive to breathe being triggered by low oxygen levels. Too much oxygen would lead to the patient losing their drive to breathe.
