On this page, clinicians and clinical researchers involved or interested in the VENT-IHCA study can find information about the study workflow and practical implementation.
The VENT-IHCA study is a prospective observational study in which ventilation is directly measured by having cardiac arrest teams apply the EOlife device (Archeon, Besançon, France) during cardiopulmonary resuscitation (CPR) of adult patients with in-hospital cardiac arrest. The EOlife device measures air flow in a blinded mode, allowing detailed recording of key ventilation parameters such as ventilation rate and tidal volumes, while clinical teams remain unaffected by the measurements and deliver usual care.
In the VENT-IHCA study, cardiac arrest teams carry a small study kit together with their standard equipment.
The EOlife device
Single use flow sensors
Flexible catheter mounts ("flextubes")
The cardiac arrest teams apply the device as soon as possible during CPR of adults with an in-hospital cardiac arrest.
Attach flow sensor to device
Start device by pushing the start button
The starts automatically
Connect flow sensor to ventilation bag
The device can be used with a bag-valve-mask and advanced airway devices including endotracheal tubes.
CPR is terminated
The patient is handed over by the cardiac arrest team to another clinical team – For example the intensive care unit staff who manage post-resuscitation care
The flow sensor has to be firmly connected to the EOlife device. A "click" sound can be heard upon successful connection.
After pushing the start button once, the device will automatically start recording and can be connected to the ventilation bag.
