Breathing Rate Belt and Pressure
The SmartQ ±10kPa Differential Gas Pressure sensor (3139) and Breathing Rate belt (3190) in this pack are used together to measure the expansion and contraction of a person’s chest while they breathe.
The Breathing Rate belt is wrapped around a person’s chest region. Fitted inside the Belt is an inflatable air bladder, which is moulded to two rubber tubes. One of these tubes finishes with a hand pump bulb that is used to inflate the air bladder. The other tube is attached to the Gas Pressure Sensor which monitors the change in pressure during breathing.
