“CPR Posture” for Hemorrhage Control

“…Methods: Participants, recruited as a convenience sample, were randomized and instructed to use either two hands overlapping using arm strength only, or two hands overlapping with arms straight in a “CPR-like” position to apply force to a standardized hemorrhage control trainer with electronic feedback (Z-Medica), set to record a minimum pressure of 3-psi (155 mmHg); representing as satisfactory pressure to occlude blood flow. Participants were allowed to train for 30 seconds and then were asked to hold pressure at or above 3-psi for a three-minute time period. …”

Treatment of Severe Hypercapnic Respiratory Failure Caused by SARS-CoV-2 Lung Injury with ECCO2R Using the Hemolung Respiratory Assist System by Ramiro Saavedra-Romero, Francisco Paz, John M. Litell, Julia Weinkauf, Carina C. Benson, Lisa Tindell, Kari Williams

“…ECCO2R is similar to extracorporeal membrane oxygenation (ECMO) but operates at much lower blood flows (350–550 mL/min) through a smaller 15.5 French central venous catheter. …”
