Normal EtCO2 Waveform Capnography Monitor Device

What Is a Capnography Monitor

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 Awrr Capnography Monitor Machine for Sale
We have ETCO2 powerpoint 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.

EtCO2 Monitors
Kingst carbon dioxide monitor adopts non-dispersive infrared spectroscopy technology(NDIR), which can measure the concentration or partial pressure of carbon dioxide.

EtCO2 Modules
The end-tidal carbon dioxide modules (EtCO2 modules) are available to be used with multi-parameter patient monitors, ventilators and anesthesia machines for monitoring of real-time ETCO2 concentration, etc.

Anesthesia Multi-Gas Detector
Kingst Anesthetic Gas Detector/Module can measure both of the concentration waveform and data of CO2, N2O，anesthetic gas, as well as respiratory rate.

Anesthesia Multi-Gas Monitors
Anesthetic Gas Monitors measure and monitor the concentration of CO2, functional oxygen saturation SpO2, Pulse and N2O concentrations, etc.

Accessories For ETCO2 & Anethesia Multi-Gas Monitors and Modules
Kingst consumables and accessories are all made of high-quality raw materials, with superior performance.

Operation Principles of Capnography BVM Monitor Device
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 Infrared Capnography
Monitoring Devices Parameters
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. ET CO2 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 monitor machine uses?
Waveform capnography measures end-tidal partial pressure of carbon dioxide. This partial pressure value is called inline 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.
