Abstract

The present disclosure is directed towards apparatuses, systems and methods for providing improved sensor-based patient monitoring and tracking. In accordance with one aspect, a method is provided for adjusting a vital sign alarm threshold of a vital status sensor as a function of a patient's GPS data, which may comprise: altitude data, velocity data, and position data. In accordance with another aspect, a method is provided for adjusting one or more alarm detection parameters based in part on a patient's calculated heart rate variability (HRV) data. According to yet another aspect, an electronic triage tag is configured to include a colored card insertion region for inserting a colored card for preventing the device from being inadvertently activated, an LCD screen and a series of LEDs for displaying the triage status of a patient (red, yellow, green, black).
