Brief summary

Differential diagnosis: ultrasound, blood gas analyse combined with examination of the patient and environment is used during Out Of Hospital Cardiac Arrest (OHCA) to screen possible underlying cause of cardiac arrest. Helicopter Emergency Medical Service (HEMS) in Helsinki has unraveled a protocol for performing differential diagnosis during OHCA. Our study aim is to test the feasibility of this protocol. Our study is a prospective medical record based study. The anesthesiologist operating in the HEMS unit fills a form after encounter of OHCA. Questioners focus on how long did execution of the protocol take, and the cause if the protocol was not completed.

Design outcomes

Primary

Measure	Time frame	Description
Successful execution of differential diagnosis protocol	60 minutes	Successful and all-inclusive execution of the following items during cardiopulmonary resuscitation: ultrasound examination, arterial blood gas analyze, clinical examination, obtaining structured history from next of kin and searching of the environment.

Secondary

Time needed to complete the differential diagnostics protocol	60 minutes	Delay from patient encountered by the prehospital critical care physician to the all diagnostics performed (during cardiopulmonary resuscitation)
