Fig. 4From: Ultra-low tidal volume ventilation during cardiopulmonary resuscitation shows no mitigating effect on pulmonary end-organ damage compared to standard ventilation: insights from a porcine modelMIGET measurements. a Relative shunt volumes, expressed as a percentage of cardiac output (CO), serve as an indicator for a ventilation/perfusion mismatch and the diversion of pulmonary gas exchange through circulatory bypass. b The ratio of high V/Q units, represented as a percentage of cardiac output (CO), indicates lung areas that are over-ventilated but have inadequate blood flow to effectively participate in gas exchange. *p < 0.05 (IPPV vs. sham at T6).
