Summary

As point-of-care ultrasound (POCUS) is becoming more available in the prehospital setting, it can be potentially used for more accurate and directed pressure application, thanks to its ability to image the artery and the underlying bony surface. The investigators therefore aim to conduct a feasibility study on healthy volunteers, to test the efficacy and tolerability of external abdominal compression using an ultrasound probe to obstruct blood flow in the abdominal aorta.

DEVICE

An Ultrasound Guided Aortic Compression for Arresting Abdominal Aortic Blood Flow

A second ultrasound device will be used to perform abdominal aortic pressure under vision. A curved probe will be placed on the upper abdomen, above the umbilicus, in the midline position and transverse orientation. The operator will have up to 2 minutes to obtain the desired sonographic view that allows for the compression to begin, with the middle of the probe, the abdominal aorta and the vertebra along the same line. Once the view is obtained, as declared by the operator and confirmed by a member of the study team, time required to obtain this view will be recorded, and recording of the common femoral blood flow will begin (for baseline) for 10 seconds, followed by 30 seconds of compression attempt (of which the compressing ultrasound view will also be recorded synchronously). At the end of the experiment, the participant will be requested to rate their level of discomfort between 0 and 10 (NRS - Numerical Rating Score)
