End Tidal Capnography Background Indications Technical Considerations

Capnography is the monitoring of end-tidal carbon dioxide in waveform and numeric display.

. Table of Contents. For this technology to be useful the critical care nurse must have a clear understanding of the normal capnography waveform and what the alterations in this waveform represent. ETCO 2 levels reflect the adequacy with which carbon dioxide CO 2 is carried.

Figure 1 Diagram of a normal capnogram that includes the inspiratory and expiratory phase. Although the normal range for CO2 should be between 35-45mmHg CO2 monitoring gives healthcare providers a lot more insight into what is going on with a patients condition. Phase 0 inspiratory phase.

Or partial pressure of carbon dioxide measured somewhere near the mouth at the end of a normal exhalation hence end tidal end of tidal volume breath To. End-tidal CO2 EtCO2 monitoring is a noninvasive technique which measures the partial pressure or maximal concentration of carbon dioxide. The critical care nurse can use this information to plan patient care.

Circulating blood CO 2. End-tidal carbon dioxide monitoring in neonatesInfant 2008. A normal capnograph Figure 1 has a square-wave pattern which begins in inspiratory phase peak expiratory CO2 PECO2 0 mmHg and will continue until the expiratory phase 6.

What is ETCO2. It is the standard of care during certain. In normal lungs the end-tidal CO 2 tension is 0508 kPa less than the arterial CO 2 tension and is a useful non-invasive estimate of arterial CO 2.

Levels range from 30s and 40s. End tidal CO 2 monitoring is represented as a number and a graph on a monitor. Happens suddenly with an inspiration.

The number is called capnometry which is the partial pressure of CO 2 detected at the end of exhalation. 35-45 mmHg End-tidal CO2 EtCO2 monitoring is a noninvasive technique which measures the partial pressure or maximal concentration of. End-tidal carbon dioxide ETCO 2 is the level of carbon dioxide that is released at the end of an exhaled breath.

The level of CO 2 gradually rises during exhalation showing an approximate equalization with the CO 2 value in alveoli in the lungs hence the phrase end-tidal. In patients with normal pulmonary function CO 2 normally 35 to 45 mm Hg and ETco 2 should correlate closely with a deviation of about 2 to 5 mm Hg. Objectives In the UK 20 of patients with severe traumatic brain injury TBI receive prehospital emergency anaesthesia PHEA.

End-tidal CO2 ETCO2 monitoring is not a new modality in the pediatric emergency department PED and emergency department. Non-invasive carbon dioxide monitoring Key points Harigopal S Satish HP.
