The carbon dioxide monitor produced by Kingst adopts non-dispersive infrared spectroscopy technology (NDIR). Etco2 monitor uses are siginificantly wide. The et co2 monitor can measure the concentration or partial pressure of carbon dioxide in the patient's exhaled breath, and then assist in judging the pathological characteristics of the patient.
The EtCO2 Monitor measures the partial pressure or concentration of carbon dioxide in the patient's exhaled breath to assist in judging the patient's ventilation status, spontaneous breathing and circulation recovery, etc.,
And the products produced by Kingst are portable and can be used in various emergency situations. For example, first aid or pre-hospital first aid, as well as transportation inside and outside the hospital, provide convenience for medical staff and greatly improve the medical level.
The capnography waveform can directly reflect the patient's ventilation status and dead space at this time. The waveform diagram is divided into four quadrants, namely the inspiratory phase, ascending phase, alveolar plateau phase, and descending phase. The end of the alveolar plateau is the peak of ETCO2, which is also the point we monitor.
The first phase: no gas participates in the interaction, 0 baseline
The second phase: the initial, rapid rise stage of exhalation
The third phase: slowly ascending, reaching the alveolar platform
The fourth phase: rapid descent to the beginning of inspiration.
From the waveform, we can judge the patient's ventilation and dead space, so as to provide clinical guidance.
End-tidal carbon dioxide concentration is lower than normal, which is often positively correlated with the patient's alveolar hyperventilation or the reduction of CO2 entering the alveoli1.Respiratory frequency and peak phase are normal, but ETCO2 is too low. Seen in mechanical ventilation with excessive tidal volume; in patients with shock and hypothermia 2. Brady breathing, peak phase, and low ETCO2 value. Such as artificial ventilation, the frequency is too slow, the tidal volume is too large; 3. tachypnea, short peak phase, low ETCO2 value. The frequency and tidal volume of artificial ventilation are too high.
End-tidal CO2 monitoring is a non-invasive, convenient, real-time and continuous functional detection index. It is another major advancement of non-invasive technology for monitoring lung function, especially providing a clear indicator for respiratory support and respiratory management in anesthesia patients, emergency department, ICU, and respiratory department.
End-tidal carbon dioxide has been considered to be the sixth basic vital sign besides ECG, blood oxygen, blood pressure, body temperature, and respiration.
Capnography monitor can be applied to emergency department, respiratory department, anesthesiology department, ICU, etc.
The purposes of our monitoring are: monitoring ventilation function; adjusting ventilator parameters and guiding ventilator evacuation; determining the position of tracheal tube; understanding alveolar dead space and changes in pulmonary blood flow; evaluating circulatory function during CPR; airway positioning, etc.
It is a monitor that can measure the carbon dioxide concentration or partial pressure in the patient's exhaled breath
The main purpose of monitoring ETCO2 is to judge the patient's ventilation, spontaneous circulation recovery, and the position of tracheal intubation according to the measured data, so as to provide convenient and effective help for doctors by using our portable end tidal co2 monitor.
The high or low value of portable end tidal co2 monitor may mean that the patient's ventilation has changed, it may be due to excessive ventilation or insufficient ventilation, or the working parameters of the ventilator may be set incorrectly.
