LPM stands for Liters per minute, a respiratory abbreviation.

Unit of flow rate used for supplemental oxygen and ventilator gas delivery, as set on a flowmeter or oxygen concentrator. Orders and nursing notes record oxygen therapy as a flow in LPM along with the device used.

Example: Home oxygen 3 LPM via nasal cannula at rest, 4 LPM with exertion.

Usage notes

Also written L/min, which most style guides and SI conventions prefer. The same flow gives very different oxygen concentrations depending on the device: 6 LPM through a nasal cannula delivers far less oxygen than 15 LPM through a nonrebreather. Home concentrators typically provide up to 5 to 10 LPM.
