Vital Signs Monitoring of Emergency Responders in Different States

The goal of this observational study is to learn about emergency responder in different states. The main questions it aims to answer are:

• Ten vital signs and behavioral parameters in different states (quiet, after post, after physical training) including: respiratory rate, pulse rate, oxygen saturation, body position, chest and abdominal respiratory movements, electromyography (EMG), electroencephalogram (EEG), partial pressure of end-expiratory CO2 concentration, partial pressure of transcutaneous oxygen, and partial pressure of transcutaneous carbon dioxide.
• Eight vital signs and behavioral parameters in different environments (altitude, confined space, energized work, job site) including: respiratory rate, pulse rate, oxygen saturation, body position, chest and abdominal respiratory movements, electromyography (EMG), electroencephalogram (EEG), and partial pressure of end-expiratory CO2 concentration.

Participants will normal operating conditions, the researcher collects vital sign information.
