Background: Current guidelines for cardiopulmonary resuscitation (CPR) emphasize reducing pauses in chest compressions, and suggest ventilating with 1 second inspiration time and with enough volume to produce normal chest rise 10 times per minute. No specific advice is provided on how ventilations should be timed with ongoing chest compressions. We have compared hemodynamic effects of ventilating synchronously vs. asynchronously during chest compressions in a porcine model. Methods: Twenty anaesthetized domestic pigs (approx. 30 kg) were randomized into two groups; synchronous vs. asynchronous ventilation. Ventricular fibrillation is induced electrically and left for 2 minutes before initiation of basic 30:2 CPR for 4 minutes. CPR with continuous mechanical chest compressions was continued for another 8 minutes with either synchronous or asynchronous ventilation before defibrillation was attempted. Aortic, right atrial and intracerebral pressures, carotid and cerebral blood flow and cardiac output (thermodilution) were measured. Airway monitoring included capnography and spirometry. Results: Hemodynamics, blood gas analysis and airway pressures were similar for both groups during baseline and 30:2 CPR periods. The asynchronous group had higher median peak inspiratory airway pressure (94 vs. 57 cm H 2 O, p<0.001) and lower EtCO 2 (1.8 vs. 3.5 kPa, p=0.023) compared to synchronous group during the last 30 seconds of CPR (after 12 minutes). Asynchronous group also had higher pH (7.55 vs. 7.35, p<0.001), lower pCO 2 (2.4 vs. 4.7, p<0.001) and higher pO 2 (62.1 vs. 29.4, p<0.001) compared to synchronous group. There were no significant differences in any of the measured hemodynamic variables between the two groups with similar coronary and cerebral perfusion pressures. ROSC was achieved in 5/10 vs. 3/10 animals in the synchronous and asynchronous groups, respectively. Conclusion: Synchronous and asynchronous ventilation during mechanical chest compressions provide similar hemodynamics, but guideline-compliant asynchronous ventilation yields significantly higher airway pressures and hyperventilation. Implications for lung injury need to be assessed.

Background The high rate of clinical failure of prosthetic arteriovenous grafts continues to suggest the need for novel tissue-engineered vascular grafts. We tested the hypothesis that the decellularized rat jugular vein could be successfully used as a conduit and that it would support reendothelialization as well as adaptation to the arterial environment. Materials and methods Autologous (control) or heterologous decellularized jugular vein (1 cm length, 1 mm diameter) was sewn between the inferior vena cava and aorta as an arteriovenous graft in Wistar rats. Rats were sacrificed on postoperative day 21 for examination. Results All rats survived, and grafts had 100% patency in both the control and decellularized groups. Both control and decellularized jugular vein grafts showed similar rates of reendothelialization, smooth muscle cell deposition, macrophage infiltration, and cell turnover. The outflow veins distal to the grafts showed similar adaptation to the arteriovenous flow. Both CD34, CD90 and nestin positive cells, as well as M1-type and M2-type macrophages accumulated around the graft. Conclusions This model shows that decellularized vein can be successfully used as an arteriovenous graft between the rat aorta and the inferior vena cava. Several types of cells, including progenitor cells and macrophages, are present in the host response to these grafts in this model. This model can be used to test the application of arteriovenous grafts before conducting large animal experiments.
