SAR helicopter paramedic practice: EtCO₂ measuring to assist with CPR attempts

Abstract

This article is a review of literature conducted in as systematic manner using the PRISMA statement as a basis for its methodology to answer the following question: How can EtCO2 measuring assist with CPR attempts in SAR Helicopter paramedic practice?’ Results revealed that CO2 coming out of an ET tube indicates that it is in the correct position. An EtCO2 value of <1.33 KPa or an EtCO2 that falls by ≥ 25% of the baseline are the variables most significantly correlated with not achieving ROSC. Diminishing EtCO2 readings may be an indication to increase CC depth, or change a tiring CC provider to optimise CPR attempts. A sudden rise in EtCO2 is a highly specific but non-sensitive marker of ROSC.
