METTCARE M-Blue is a way of providing a real-time alarm notification on a provider’s mobile device related to the so-called ‘Cold Blue’ events in hospitals. The alarming statistics of patient’s outcome in a case of cardiopulmonary arrest are reason enough to deploy M-Blue. Only 25% of patients who lose a heartbeat will ever get it back and only 3% of patients whose heart stops on a general ward will leave the hospital alive . METTCARE app connects to an existing notification system, and distributes the notification to a pre-set team of healthcare providers. METCTARE does a full verification of the alarm source and target mobile devices and keeps a full audit of alert activity. This prevents a malicious use of the alert system and keeps a verifiable source of the alert activity for legal purposes.
