简要总结
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.
详细描述
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.

- •Minimum age of 18 years
排除标准
- •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

结局指标
主要结局
Results of the concurrently conducted manual pulse check
时间窗: During cardiac arrest, up to 45 minutes
Parallel to our study team the treating team will conduct standard care, consisting of determining the presence or absence of a pulse by palpation. The results of these manual pulse checks will be recorded by our study team.
Results of POCUS pulse check
时间窗: During cardiac arrest, up to 45 minutes
If the femoral artery is both non-compressible and pulsatile, the POCUS pulse check will be considered positive
次要结局
- Arterial compressibility during rhythm checks(During cardiac arrest, up to 45 minutes)
- Arterial pulsatility during rhythm checks(During cardiac arrest, up to 45 minutes)
- Arterial compressibility during chest compressions(During cardiac arrest, up to 45 minutes)
- Time needed for POCUS pulse checks(During cardiac arrest, up to 45 minutes)
