The Haemodynamic Effects of Mechanical Standard and Active Chest Compression-decompression During Out-of-hospital CPR

The Haemodynamic Effects of Mechanical Standard and Active External Chest Compression-decompression During Out-of-hospital Cardiopulmonary Resuscitation

The aim of this randomized out-of-hospital cardiopulmonary resuscitation study is to investigate haemodynamics generated by the standard mechanical external chest compression device (LUCAS™ 2) compared to a new version generating chest compressions and active decompression above the initial starting position of the suction cup (LUCAS™ 2AD).

Based on randomization patients will receive standard or active compression decompression chest compression and the haemodynamic effects will be compared.

Inclusion Criteria:

• Unexpected adult out-of-hospital non-traumatic cardiac arrest where an attempt of resuscitation is considered appropriate in:
• Patients 18 years or older

Exclusion Criteria:

• Traumatic cardiac arrest
• Age believed to be less than 18 years
• Known pregnancy
• Victim not to be resuscitated (DNR orders)
• Internals in prison
• Included once in the study already
• To Small/Large patients
• Sustained ROSC occurring before the LUCAS™ 2 or LUCAS™ 2-AD can be applied to the patient, such that further CPR is not needed
