Physio-Control is recalling 622 LIFEPAK 15 V4 monitors due to a software error that prevents monitoring of carboxyhemoglobin and methemoglobin saturation levels in affected sensors.

The agency’s classification

FDA (Devices): Class II

Class II is a situation in which use of or exposure to a violative product may cause temporary or medically reversible adverse health consequences, or where the probability of serious adverse health consequences is remote.

This is the agency’s own classification, taken from its notice. The severity score below is our assessment, not the agency’s. How recall classes work

What this means for you

Our assessment, not the agency’s: severity 3/5 (High).

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: FDA Class II device with a software error that disables critical monitoring capabilities. The disabled sensors detect serious poisoning and metabolic conditions; while no injuries have been reported, the error creates risk of harm in affected healthcare settings where these monitoring parameters may be clinically necessary.
