Trauma Patients
Patients suffering blunt and/or penetrating trauma but without physiologic criteria suggestive of ongoing hemorrhage: 1. Awake and alert GCS \>14 2. Admission systolic blood pressure greater than 90 and heart rate less than 120 3. Without signs of clinically significant ongoing external hemorrhage with no active bleeding documented on radiology/ultrasound and stable vital signs (no signs of hemodynamic deterioration) during initial evaluation (approximately 15 minutes post admission) Detection of Occult Hemorrhage in Trauma Patients: Non-invasive monitoring of trauma patients

PRIMARY outcome

Timeframe: patient data will be collected over 3-6 hours

Population: Only 1 participant was enrolled was stable for 6 hours (no signs of hemodynamic deterioration). Therefore there was no data to analyze algorithm performance. Algorithm developed was to be trained to alarm under two circumstances indicating significant risk of ongoing hemorrhage progressing to shock: 1) a change from baseline, 2) development of prespecified patterns. This participant did not experience a triggering event, and therefore there was no data to be used to evaluate the algorithm.
