Normal EtCO2 Waveform Capnography Monitor Device

• 

As a technology-based company, we have been focusing on developing and innovating carbon dioxide modules and monitors for more than 20 years. And we have been promoting etco2 series modules and cooperating with many well-known medical companies since 2008. Our products have obtained CE and ISO9000 certifications, and all products conform to RoHS. In 2020, its mainstream and side stream etco2 modules have been certified by US FDA. In addition, Beijing Kingst Commercial has successively launched the AneSure series of mainstream and side stream multi-gas modules and multi-gas monitors.

Types of Capnography Monitor Machine for Sale

We have ETCO2 products and anesthetic multi-gas products. The ETCO2 products are divided into ETCO2 monitors and ETCO2 modules. And Anesthetic multi-gas products are divided into Anesthetic Gas Detectors and Sensors. In addition, there are consumables to match the above modules and monitors.

Operation Principles of Capnography machine

The partial pressure of CO2 in the end-breathing gas can be determined according to the principle of infrared spectroscopy, mass spectrometry or spectroscopy.

Among them, infrared spectroscopy is the most widely used method. It mainly uses CO2 to absorb infrared rays with a wavelength of 4.26um, which attenuates the amount of infrared beams. The degree of attenuation is proportional to the CO2 concentration.

Understanding Normal Capnography Monitoring DevicesParameters

End-tidal CO2 concentration, or partial pressure (ETCO2), measured by Capnography Monitoring Devices, reflects pulmonary ventilation as well as pulmonary blood flow. When there is no obvious cardiopulmonary disease and the V/Q ratio is normal. ETCO2 can reflect PaCO2 (arterial blood carbon dioxide), normal ETCO2 is 5% equivalent to 5KPa (35-45mmHg).

When end-tidal carbon dioxide is too high: its physiological significance is that the alveolar ventilation is insufficient or the input of CO2 to the alveoli increases. And when End-tidal carbon dioxide is too low: mainly alveolar hyperventilation or reduced CO2 input to the alveoli.

What is waveform capnography monitormachine uses?

Waveform capnography measures end-tidal partial pressure of carbon dioxide. This partial pressure value is called end-tidal CO2 or EtCO2. Its waveform can provide doctors with important information about a patient's health. Such as airway positioning, whether breathing is inhibited, and whether spontaneous breathing is restored as well as guidance on ventilator work.

Normal EtCO2 levels are 35 to 45 mm Hg and the waveform is generally trapezoidal. As the respiratory rate and tidal volume change, so do the waveforms and values.

As one of the most professional capnography machine, we provide waveform capnography machine, waveform capnography device, etco2 machine, etc. For more information about etco2 waveform capnography, please feel free to contact us!
