What is a sidestream capnography?

What is a sidestream capnography?

In side-stream capnography, the CO2 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.

What is sidestream and mainstream?

Mainstream capnography is characterized as invasive and non-diverting, meaning that the measurement of the ETCO2 is done at the airway, or the sample site, thus providing a real-time measurement of the carbon dioxide pressure. Sidestream, on the other hand, is non-invasive and diverting.

What is microstream ETCO2?

Microstream™-enabled technology is used worldwide to help clinicians monitor patients’ end-tidal CO2 (etCO2) and alert them early to indications of evolving respiratory compromise.

What is capnography monitoring?

A capnography monitor is used in healthcare facilities to measure end tidal CO2 (EtCO2), or the amount of carbon dioxide a patient exhales. Typically, monitoring this exchange is important when a patient goes under anesthesia, but it can also be useful in other scenarios as well.

What does ETCO2 measure?

End-tidal CO2 (EtCO2) monitoring is a noninvasive technique which measures the partial pressure or maximal concentration of carbon dioxide (CO2) at the end of an exhaled breath, which is expressed as a percentage of CO2 or mmHg. The normal values are 5% to 6% CO2, which is equivalent to 35-45 mmHg.

What are Sidestreams?

Sidestreams refer to any process flow resulting from the treatment of biosolids that flows back into the liquid treatment train (i.e. centrate). Nutrient-rich sidestreams are returned to the liquid stream process during dewatering, increasing the influent nitrogen and phosphorus loading to the secondary process.

What causes shark fin capnography?

With bronchoconstriction, caused by asthma, COPD, and sometimes pneumonia, air is released inconsistently from the constricted lower airways. This causes the normally rectangular-shaped capnography waveform to have a “shark-fin” appearance [1].

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 happens when a patient Hypoventilates?

Hypoventilation is breathing that is too shallow or too slow to meet the needs of the body. If a person hypoventilates, the body’s carbon dioxide level rises. This causes a buildup of acid and too little oxygen in the blood.

What is the difference between a mainstream and sidestream capnography monitor?

For example, a mainstream capnograph may provide a shorter response time because the EtCO2 doesn’t have to travel as far to reach the sensor, but a sidestream capnography monitor may be more comfortable for the patient because the thin tubing that is connected is lighter and less bulky than a mainstream version.

How is CO2 measured in side-stream capnography?

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. The sampling tube is connected to a T-piece inserted at the endotracheal tube or anesthesia mask connector.

What is a capnography monitor and how does it work?

A capnography monitor is a machine that measures the exchange of carbon dioxide through a patient’s respirations.

What is a sidestream CO2 monitor?

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.
