Final answer:
Oxygen therapy for patients with emphysema typically requires 1 to 2 liters per minute (LPM), carefully adjusted based on individual needs and blood gas analyses to maintain oxygen saturation between 88% to 92% and prevent CO2 retention.
Step-by-step explanation:
The provision of oxygen for patients with emphysema must be done with caution, as their ability to expel carbon dioxide (CO2) may be compromised. The goal is to maintain the oxygen saturation between 88% to 92%, which usually requires low-flow oxygen. The amount of oxygen per minute (LPM) varies depending on each individual's condition, but it typically ranges between 1 to 2 liters per minute (LPM) via nasal cannula. A healthcare provider will adjust the flow based on blood gas results and the patient's overall condition. It's essential to avoid giving too much oxygen, which can suppress their drive to breathe and exacerbate CO2 retention.
