Objective: To assess the amount of abdominal pressure generated by the Non-pneumatic Anti-Shock Garment (NASG), a first-aid counter pressure device for obstetric hemorrhage, and to evaluate if body mass index (BMI) and applier strength, affect pressure. Study Design: A pilot study convenience sample of 20 non-pregnant volunteers underwent external abdominal pressure monitoring with NASG placement. Mean pressure and the effects of BMI and applier strength were examined. Results: The mean external abdominal pressure significantly increased from 1.0 mmHg at baseline to 67 mmHg on NASG application, returning to 1.0 mmHg upon removal (p=0.005). Greater mean pressure was exerted by a strong applier versus a weak applier, irrespective of BMI (p
