A breath monitor device useful for monitoring the inhaling and exhaling of patients and particularly patients on a breathing apparatus, the device being constructed to have a sensor element positioned in the path of the breath flow to respond to the breath and to the constituants thereof, the breathing apparatus including structure for supporting the sensor element, and a control circuit connected to the sensor element including a circuit portion for amplifying responses produced by the sensor element, a circuit portion for establishing threshold conditions for indicating whether the individual patient being monitored is inhaling or exhaling and that the patient is using the oxygen being breathed at a set minimum rate, a control panel connected to the control circuit including a first indicator for indicating when the patient is inhaling, a second indicator for indicating when the patient is exhaling, and a control element adjustable to establish minimum safe breathing rate conditions including an alarm device for producing an alarm condition when a breathing rate being monitored either falls below the minimum safe rate or ceases indicating a respiratory blockage or breathing failure. A counter circuit for counting the breath rate of the patient is also provided.
