APNEA monitor |
摘要 |
An infrared fluid analyzer with an improved sensitivity and signal to noise ratio is provided. The device includes a capacitor microphone for detecting absorption of characteristic infrared wavelength lines by the sample and utilizes an electret material to electrically polarize the capacitive element in the microphone. The device is used to detect a stoppage of respiration in a person and thereby warn of the presence of an APNEA condition. The capacitor microphone generates a signal each time it detects an exhaled breath. When a timer senses an extended delay between signals, an alarm sounds indicating the presence of an APNEA condition.
