A capnometer monitors the amount of carbon dioxide a patient exhales. This allows the healthcare provider to perform a comprehensive assessment of the patient's ventilation. In order to produce healthy levels of carbon dioxide, the patient's breathing must be healthy. They have to draw air into their lungs and do good alveolar breathing in the lung cavities. They must have good circulation to return carbon dioxide from body tissues to the lungs and good cellular respiration within the tissues. Healthy carbon dioxide levels mean the patient is breathing well overall.
Capnography monitor works by shining infrared light on the patient's breathing tube. Carbon dioxide absorbs infrared light, so the more carbon dioxide present, the less light the sensor receives. This allows the sensor to determine how much carbon dioxide the patient exhales. The sensors send their data to the monitor, which is displayed in two ways. First, it visually depicts the rise and fall of CO2 levels as the patient exhales and produces a waveform, which is called a capnogram. Second, it shows end-tidal carbon dioxide, usually 30 to 45 mmHg, which is called capnography. A good capnography monitor will display both data so that the healthcare provider can get a complete picture of the patient's status immediately. Here, we recommend ekingst portable end tidal co2 monitoring devices to you.
Intensive care settings often use pulse oximeters to monitor a patient's breathing and circulation. Capnography, however, is a more sensitive and comprehensive way of measuring breathing and circulation problems. If you are interested, you can follow our capnography monitor for sale. Here are some advantages of capnography over pulse oximeters.
Show hypoventilation sooner, monitor oxygen with pulse oximeter. Similar to capnography, it uses infrared light to measure how much oxygenated blood is circulating to peripheral tissues. Capnography measures directly from the patient's breath. Any changes in breathing are recorded immediately by the capnometer. This provides healthcare workers with the advantage of early detection of respiratory problems.
With greater specificity, pulse oximetry readings may be confounded by other factors. If the patient becomes hypothermic, blood will shunt away from the extremities, causing false low oxygen readings. Likewise, in patients with poor distal perfusion, it is not possible to obtain a true assessment of oxygen saturation. Pulse oximeters are used in many clinical situations. However, capnography is the fastest and most specific method of monitoring a patient's respiratory status.
