What is sidestream CO2?
What is sidestream CO2?
Sidestream CO2 uses a sensor that is located inside the monitor instead of an external sensor. For this method, the patient’s exhalation air is pulled through a small tube, usually 6-8′ long, from the sample site (usually a nasal cannula or a mask) and into the monitor.
What are the three types of ETCO2 monitors?
Three primary types of ETco2 monitors are available: sidestream, mainstream, and Microstream®.
What is the difference between capnography and capnometry?
Capnography is the continuous analysis and recording of the CO2 concentration in respiratory gas. Although the terms capnography and capnometry are sometimes considered synonymous, capnometry means only the measurement of CO2 in respiratory gas (ie, analysis alone), without a continuous written record or waveform.
What do mainstream smoke and sidestream smoke have in common?
Mainstream smoke: The smoke exhaled by a person who smokes. Sidestream smoke: Smoke from the lighted end of a cigarette, pipe, or cigar, or tobacco burning in a hookah. This type of smoke has higher concentrations of nicotine and cancer-causing agents (carcinogens) than mainstream smoke.
What is a mainstream EtCO2?
A capnography monitor is a machine that measures the exchange of carbon dioxide through a patient’s respirations. At the end of an exhale, an amount of carbon dioxide called the end tidal CO2, or EtCO2, is released.
What is a capnography test?
Capnography is a non-invasive measurement during inspiration and expiration of the partial pressure of CO2 from the airway. It provides physiologic information on ventilation, perfusion, and metabolism, which is important for airway management.
Is capnography and ETCO2 the same thing?
Waveform capnography represents the amount of carbon dioxide (CO2) in exhaled air, which assesses ventilation. It consists of a number and a graph. The number is capnometry, which is the partial pressure of CO2 detected at the end of exhalation. This is end-tidal CO2 (ETCO2) which is normally 35-45 mm Hg.
What does it mean if ETCO2 is high?
For patients who present with a high ETCO2 reading, a decrease with treatment indicates that they are getting better. No change or a rising ETCO2 level indicates that respiratory effort is still failing to adequately eliminate CO2, and that more other interventions are needed.
What are the advantages and disadvantages of capnography?

Where is the CO 2 sensor in side stream capnography?
Difficult to use in unusual patient positioning such as in prone positions. In side-stream capnography, the CO 2 sensor is located in the main unit itself (away from the airway) and a tiny pump aspirates gas samples from the patient’s airway through a 6 foot long capillary tube into the main unit.
How many dogs are in a sidetream capnograph?
Design: Randomized, double Latin square. Animals: 6 healthy adult dogs. Procedure: Anesthesia was induced and neuromuscular blockade achieved by IV administration of pancuronium bromide.
How is a sample cell attached to a capnograph?
Main-stream capnographs. In the mainstream capnograph, a sample cell or cuvette (airway adapter) is inserted directly in the airway between the breathing circuit and the endotracheal tube. A lightweight infrared sensor is then attached to the airway adapter.
