A personal alarm device 1 , for warning an individual of the presence of an unhealthy amount of carbon monoxide in the blood of said individual, comprises a mouthpiece 5 , a carbon monoxide detector and means for emitting an alarm. The mouthpiece is adapted to receive the breath exhaled by an individual and direct the breath to said detector. The detector is adapted to detect a minimum predetermined amount of carbon monoxide in said breath and to emit an alarm when said minimum predetermined amount is detected. n The device is particularly useful in a patient-controlled method of treatment to abate tobacco use. |
