Integrated Respiratory Effort Snore & Body Position Sensor (RESBP)
The integrated sensor is powered by the WatchPAT device and does not
require a battery. It is automatically activated by the WatchPAT when plugged
into the Snore & Body position port. The snore sensor is an acoustic decibel
detector. It uses a very sensitive microphone that responds to snoring and
other sounds in the audio range and converts them to a small analog voltage
that provides a clear, reliable indication of the presence of these sounds.
The body position sensor uses a 3-axis accelerometer that provides a signal
directly proportional to the patient's sleeping posture (supine, prone, right,
left and sit). The chest movement signal uses the same 3-axis accelerometer
to provide raw chest movement signal data for measuring subject’s breathing
during the night.
Description
The RESBP sensor is an accessory of the WatchPAT home care device for
use with patients suspected to have sleep related breathing disorders. The
integrated sensor monitors the snoring level, which aids in the evaluation
of the severity of sleep related breathing disorders, and the body position
which aids in the evaluation of the type of sleep related breathing disorders.
The sensor also provides raw chest movement signal data to measure the
subjects breathing during the night.
