Regular maintenance ensures emergency ventilators function optimally during critical situations. Daily checks include inspecting power sources, tubing, and alarms for leaks or malfunctions. Clean external surfaces with approved disinfectants, avoiding moisture in electrical components. Replace filters and batteries as per manufacturer guidelines.

In emergencies, if the ventilator fails, immediately switch to manual ventilation using a bag-valve mask while assessing the issue. Check for disconnected tubing or power failures. If alarms indicate low oxygen or pressure, verify gas supply and patient connections. Avoid using damaged parts; prioritize patient safety by securing alternative ventilation if repairs are delayed.

Proper maintenance and swift first aid responses enhance reliability, ensuring life-saving support when needed most. Always follow manufacturer protocols for specific models.
