Emergency oxygen service is critical in healthcare settings, especially during power failures. The correct response is to ensure that the emergency oxygen supply automatically switches to backup power. This is vital because it allows for a seamless transition in service, ensuring that patients who rely on oxygen therapy continue to receive necessary support without interruption. The system being connected to a backup power source safeguards against potential risks during outages, guaranteeing ongoing access when it is most needed. This feature is often mandated by safety standards to protect patient health and safety in emergency situations. Other approaches, such as manually activating the system or shutting off emergency services, would compromise patient care and safety. Additionally, ceasing regular testing of the system is not appropriate since routine testing is essential to ensure functionality during actual emergencies.
