Nov 3, 2020 · Current ILCOR guidelines advise that capnography is useful during cardiac arrest resuscitation; ETCO2 can be used as a surrogate marker of cardiac output; USES. Uses during cardiac arrest: gradual fall in ETCO2 suggests compressionist fatigue during CPR -> time to change compressionists

Oct 22, 2015 · Continuous waveform capnography and end-tidal CO2 (ETCO2) monitoring during CPR help EMS providers assess ventilation, confirm airway placement and guide resuscitation efforts.

Aug 5, 2021 · Most studies have evaluated etCO2 after 20 minutes of CPR: etCO2 <10 mm suggests low likelihood of survival. etCO2 10-20 mm may represent a grey zone. etCO2 >20 mm suggests higher likelihood of survival. Whether or not to continue resuscitative efforts should not be based solely on etCO2 values.

ETCO2 concentration is a reliable index of effective heart compression during CPR, which is associated with cardiac output (7, 8). The first sign of the return of spontaneous circulation (ROSC) during CPR is increase in ETCO2, therefore monitoring of ETCO2 provides very useful information to guide treatment during CPR ( 8 - 10 ).

Oct 1, 2018 · On average during CPR, if adequate chest compressions are being delivered a cardiac index of 1.6-1.9 L/min/m2 can be generated, which correlates with ETCO2 pressures of 20mmHg.(1) ACLS guidelines define high quality chest compressions as achieving ETCO2 pressures of at least 10-20 mmHg.

Monitoring end-tidal carbon dioxide (ETCO 2 or capnography) as a feedback tool during cardiopulmonary resuscitation (CPR) has been discussed since the early 1980s.

Mar 21, 2025 · The main determinant of EtCO2 during CPR is the quality and effectiveness of chest compressions. Proper chest compression, in this case, means the application of techniques that will pump oxygenated content blood from the heart into the lungs of the victim.

Feb 21, 2022 · If the EtCO2 is low early in cardiac arrest, look for a reversible cause. First, assure proper chest compressions and ventilations. Next look for reversible causes of right ventricle obstruction.

In a systematic review, EtCO2 ≥ 10 to 20 mmHg during CPR was strongly associated with ROSC while persistent EtCO2 below 10 to 20 mmHg after 20 minutes of CPR had a 0.5% likelihood of ROSC. High quality CPR – consistent waveform and end-tidal CO2 > 2.0 kPa: Chest compression provider tiring – end-tidal CO2 value diminishes over time:

ETCO 2 trends can vary during CPR depending on various factors such as the cause of cardiac arrest, compression efficacy, ventilation depth and frequency, and adrenaline administration. Therefore, it is advised to use ETCO2 trends over time rather than single measurements.
