An automatic alarm and help-seeking device based on breathing signal and its detection method

Abstract

The invention belongs to the fields of life safety, biomedical engineering and wearable devices, and in particular relates to an automatic alarm and help-seeking device based on a breathing signal and a detection method thereof. The present invention detects the breathing state, that is, the user arranges and combines the three breathing states of normal breathing, rapid breathing and breath-holding in advance with n≥1 breathing states, and sets them into a specific sequence of breathing states.
