2. Carbon dioxide sensor - Wikipedia

   en.wikipedia.org/wiki/Carbon_dioxide_sensor

   New developments include using microelectromechanical systems (MEMS) IR sources to bring down the costs of this sensor and to create smaller devices (for example for use in air conditioning applications). [3] Another method (Henry's Law) also can be used to measure the amount of dissolved CO 2 in a liquid, if the amount of foreign gases is ...

3. Capnography - Wikipedia

   en.wikipedia.org/wiki/Capnography

   Capnography directly reflects the elimination of CO 2 by the lungs to the anesthesia device. Indirectly, it reflects the production of CO 2 by tissues and the circulatory transport of CO 2 to the lungs. [7] When expired CO 2 is related to expired volume rather than time, the area beneath the curve represents the volume of CO

4. Colorimetric capnography - Wikipedia

   en.wikipedia.org/wiki/Colorimetric_capnography

   Colorimetric capnography is a qualitative measurement method that detects the presence of carbon dioxide (CO2, a relatively acidic gas) in a given gaseous environment. From a medical perspective, the method is usually applied by exposing litmus paper/film to an environment containing a patient's airway gases (i.e. placing it into their breathing circuit/airway circuit), where it will then ...

5. Monitoring (medicine) - Wikipedia

   en.wikipedia.org/wiki/Monitoring_(medicine)

   Capnography, which involves CO 2 measurements, referred to as EtCO2 or end-tidal carbon dioxide concentration. The respiratory rate monitored as such is called AWRR or airway respiratory rate) Respiratory rate monitoring through a thoracic transducer belt, an ECG channel or via capnography; Neurological monitoring, such as of intracranial pressure.

6. Gas detector - Wikipedia

   en.wikipedia.org/wiki/Gas_detector

   Portable detectors are used to monitor the atmosphere around personnel and are either hand-held or worn on clothing or on a belt/harness. These gas detectors are usually battery operated. They transmit warnings via audible and visible signals, such as alarms and flashing lights, when dangerous levels of gas vapors are detected.

7. Insulation monitoring device - Wikipedia

   en.wikipedia.org/wiki/Insulation_monitoring_device

   An insulation monitoring device monitors the ungrounded system between an active phase conductor and earth. It is intended to give an alert (light and sound) or disconnect the power supply when the resistance between the two conductors drops below a set value, usually 50 kΩ (sample of IEC standard for medical applications). The main advantage ...

8. Holter monitor - Wikipedia

   en.wikipedia.org/wiki/Holter_monitor

   Each Holter system has hardware (called monitor or recorder) for recording the signal, and software for review and analysis of the record. There may be a "patient button" on the front that the patient can press at specific instants such as feeling/being sick, going to bed, taking pills, marking an event of symptoms which is then documented in the symptoms diary, etc.; this records a mark that ...

9. Carbon monitoring - Wikipedia

   en.wikipedia.org/wiki/Carbon_monitoring

   Carbon monitoring as part of greenhouse gas monitoring refers to tracking how much carbon dioxide or methane is produced by a particular activity at a particular time. For example, it may refer to tracking methane emissions from agriculture, or carbon dioxide emissions from land use changes, such as deforestation, or from burning fossil fuels, whether in a power plant, automobile, or other device.
