Summary

The aim of this observational study is to investigate how ventilations is given during cardiopulmonary resuscitation (CPR) given by advanced life support providers (ALS). A portable device capable of detailed measurments of ventilation will be used when ventilating patients suffering cardiac arrest. The main objective of the study is to describe the ventilatiosn given in terms of volume, frequency and pressure, both overall and during different CPR modes and when using different methods to handle the patients airway.

Detailed description

The aim with this observational multicenter study is to measure and describe manual ventilation during cardiopulmonary resuscitation in the advance life support setting. Primary endpoint is the ventilation quality measured as ventilation frequency, tidal volume, minute ventilation peak inspiratory pressure and exhaled CO2. This will be studied in both asycnhronous ventilations, meaning ventilations that are given during ongoing chest compressions and syncrhonous ventilations, meaning ventilations given during a pause of the chest compressions, in a 30:2 repeatign pattern. Aditionally, airway modalities such as bag-valve-masks, Supraglottic airway devices and endotracheal tubes will be studied. The inclusion of patients will be performed at five sites, The Uppsala emergency medical services, Uppsala, Sweden, Capio AB akutläkarbilar (rapid response cars), Stockholm Sweden, Falun County hospital, Falun, Sweden, EMS Amsterdam post West, Amsterdam, The Netherlands and Lifeliner 1 HEMS, Amsterdam, The Netherlands Eligible for inclusion are patients over 18 years old suffering cardiac arrest in the areas served by the including emergency medical systems and in-hospital emergency team. The goal is to include at least 200 patients.
