A capnograph measures carbon dioxide in air and is used to monitor ICU and anesthesia patients, diagnose respiratory problems, and monitor patients in emergencies. It shines infrared light through the air sample and measures how much CO2 is absorbed, producing a capnogram. Capnographers can detect breathing problems and errors in anesthesia equipment, and are used by paramedics to monitor patients before they reach the hospital. They can also measure the effectiveness of CPR without interrupting it.
A capnograph is a device that measures the amount of carbon dioxide in a sample of air. It is most commonly used to monitor ICU patients and anesthesia patients. The device can also be used as a tool to diagnose respiratory problems and monitor patients in emergency situations.
Carbon dioxide (CO2) absorbs infrared light. Infrared light is a type of light that has a longer wavelength than visible light. It can only be seen using special tools. To measure the concentration of carbon dioxide in a sample of air, a capnograph shines infrared light through the sample. Then measure the light to find out how much CO2 was absorbed.
The results of this measurement are printed as a capnogram. A capnogram is a graph that plots capnograph readings over time. It can also plot readings against the volume of air that has been inhaled or exhaled. During anesthesia, a capnographer takes his readings from the device that is delivering air to the patient. This can be a breathing mask or a tube inserted directly into the patient’s airway, called an endotracheal tube.
A capnographer is better than a human observer at knowing when something has gone wrong because he can recognize a change in CO2 before it builds up enough to cause visible symptoms. The device can detect most major breathing problems, such as decreased breathing rate, also known as hypoventilation. It can also recognize when there is a problem with the way anesthesia equipment is being used, such as when a breathing tube has been inserted into the esophagus instead of the airway. Placing a breathing tube in the esophagus can lead to death if the error isn’t noticed quickly.
Many paramedics have started using the capnograph as a patient monitoring tool before the patient reaches the hospital. In addition to making sure an endotracheal tube has been placed correctly, capnographers can also tell if a patient is having difficulty breathing or isn’t getting enough air. This can help paramedics make more informed choices about how to treat a patient.
The capnographer can also measure the effectiveness of cardiopulmonary resuscitation (CPR). It is better than other measurement devices because readings are unaffected by chest compressions. This means that a paramedic does not have to interrupt CPR to tell if CPR is helping the patient.
