Thermometer, Exhaled Breath
- Page Type
- Product Code
- Definition
- To measure the temperature of exhaled human breath, which is frequently increased in airway inflammation in asthma patients. Measurement of changes in exhaled human breath temperature aids in evaluating airway inflammation treatment in asthma patients as an adjunct to established clinical and laboratory assessments of asthma.
- Physical State
- The major components of the device are: a. A 0.5-litre silver plated flask in a metal cylinder (thermos) b. An air tube and thermal block made out of copper with an in-built temperature sensor. The thermal block has a tube-like part with high thermal capacity and excellent heat conduction properties c. Mouthpiece (Polypropylene) d. Inlet Cap (Polycarbonate) e. USB Port (Polyurethane) f. Environmental Chamber (Mild Sheet Metal) g. LCD Screen h. Navigation/Power/OK buttons (ABS)
- Technical Method
- The essence of the device technology is an environmental chamber with a thermal core heated by exhaled air from the patient. Each exhalation increases the temperature inside the reservoir until equilibrium is reached and measured by a thermal sensor. To use the device, the patient inhales through the nose and exhales into the device via a mouthpiece. The temperature in the device is assessed by measuring the resistance of the thermal sensor by means of a digital ohm-meter.

CFR § 880.2910 Clinical electronic thermometer
§ 880.2910 Clinical electronic thermometer.
(a) Identification. A clinical electronic thermometer is a device used to measure the body temperature of a patient by means of a transducer coupled with an electronic signal amplification, conditioning, and display unit. The transducer may be in a detachable probe with or without a disposable cover.
(b) Classification. Class II (performance standards).
