Philips Respironics recalls Trilogy Evo O2 ventilators with software version 1.05.15.00 due to potential obstruction alarm failure. Affected units may not trigger alarms within standard timeframes, risking breathing issues.
In some situations, the Obstruction Alarm does not trigger within the timeframe dictated by the relevant standards and may take up to four breaths.
