I have COPD, I want to buy a portable O2 unit, I use 2L/per min now. For sleeping only. They have units that deliver 2L & units that goe up to 6 l/per min. But are more expensive. Do you think the 2L /per min would be sufficient, as I have heard that COPD pts. Even if getting worse, probably shouldn't over 2L/per min. Anyway. What are your thoughts. I am a retired RN.

When managing COPD with oxygen therapy, it's essential to balance the oxygen flow to meet your needs without causing potential complications. 

COPD patients can be sensitive to higher levels of oxygen. In some cases, administering too much oxygen can lead to a condition known as hypercapnia, where carbon dioxide builds up in the blood, potentially leading to respiratory acidosis and other complications. This is why many healthcare providers recommend keeping the oxygen flow rate at a lower level, typically around 2L/min, unless a higher rate is specifically prescribed after careful monitoring.

If your oxygen needs increase in the future, you should consult your pulmonologist to reassess them. They may recommend adjustments based on your current health status, arterial blood gas results, or pulse oximetry readings. 

It's always wise to consult with your healthcare provider before making any changes to your oxygen therapy. They can help ensure that it is tailored to your specific needs and condition.

Best wishes,

Nurse Beth
