Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this prospective observational study is to investigate B-mode point-of care ultrasound with arterial compressibility assessment on the femoral artery as a method to determine the presence of a pulse and to compare it with concurrently conducted manual pulse checks.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this prospective observational study, a dedicated research team will be dispatched to cardiac arrest patients treated in the prehospital environment by emergency medical services (EMS). The team will use a portable ultrasound device to identify the femoral artery and employ B-mode ultrasound during rhythm checks. These ultrasound pulse checks will be conducted in parallel with the normal treatment of the patient, including manual pulse checks, and will only be conducted if ultrasound is possible without interference in the resuscitation. All treatment decisions will rest with the treating EMS team.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Out-of-hospital cardiac arrest treated by EMS
* Minimum age of 18 years

Exclusion Criteria

* Pregnancy or suspected pregnancy
* Disapproval of the treating EMS team
* Adults under legal guardianship
* Inability to perform femoral artery doppler ultrasound due to limited access to the patient and possible interference with the treating EMS team
* Inability to perform femoral artery doppler ultrasound due to injuries or anatomic abnormalities in the femoral region or necessary emergent medical interventions in the femoral region
* Decision to transfer the patient to the hospital with ongoing CPR for emergent procedures such as extracorporeal CPR before femoral artery doppler ultrasound could be attempted
* Inability to safely perform femoral artery doppler ultrasound due to environmental hazards
