Trilogy Evo O2 EV300 respiratory devices recalled for debris accumulation
Philips Respironics recalled 18,855 Trilogy Evo O2 EV300 devices because environmental debris may accumulate on the flow sensor, potentially causing inaccurate delivery of pressure or flow. This could result in patient hypoxemia if not promptly addressed.
The agency’s classification
FDA (Devices): Class I
Class I is a situation in which there is a reasonable probability that the use of or exposure to a violative product will cause serious adverse health consequences or death.
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 4/5 (Severe).
The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.
Our severity reasoning: This is an FDA Class I recall for a medical device with serious potential for patient harm through hypoxemia. No adverse events have been reported yet, but the FDA Class I designation and the mechanism of potential failure indicate substantial risk that would result in serious injury if the device malfunctions during clinical use.
