Background: Some North American rattlesnake venoms and angiotensin converting enzyme inhibitor (ACEI) medications each increase bradykinin levels in humans, with clinical effects attributable to bradykinin described in exposed populations. Influence of ACEI exposure on persons with snake envenomation has not been studied. We used data from the ACMT North American Snakebite Registry (NASBR) to determine if use of ACEI medications at the time of rattlesnake envenomation is associated with increased rate of systemic toxicity.

Resuscitator bags are commonly utilized in acute care settings; however, poor performance occurs irrespective of a provider's qualifications or experience. A new flow-limiting device (Sotair by SafeBVM, Boston, Massachusetts) limits inspiratory flow during manual ventilation, thus minimizing peak inspiratory pressures. This study examined the differences in flow, pressure, and tidal volume (V) during ventilation with a manual resuscitator connected to the flow-limiting device versus a mechanical ventilator.
