The setting on an oxygen machine refers to the flow rate — basically, how many liters of oxygen per minute are being delivered. So a setting of 2 means 2 liters per minute (LPM), and a setting of 3 means 3 liters per minute.

The setting on an oxygen machine refers to the flow rate — basically, how many liters of oxygen per minute are being delivered. So a setting of 2 means 2 liters per minute (LPM), and a setting of 3 means 3 liters per minute.
Since a doctor prescribed the setting of 3, that was based on what the body needs to keep oxygen levels in a safe range. Changing it without medical guidance isn't recommended. Here's why sticking to the prescribed setting matters:
- Too little oxygen can cause symptoms like shortness of breath, confusion, tiredness, or bluish lips/nails
- Too much oxygen can cause a buildup of carbon dioxide in some people with COPD, which can actually make breathing worse — this is called oxygen-induced hypercapnia
If there's any concern about whether the current setting is still right, it's worth checking in with the doctor. They may do an oxygen saturation test to see if the prescription needs adjusting.
