The Butterfly BVM by Compact Medical Inc. is a novel bag-valve-mask resuscitator that helps advanced lifesavers and other EMS personnel provide CPR according to published guidelines. The Butterfly BVM can be adjusted to deliver tidal volumes that are appropriate for a wide range of patients and can restrict peak inspiratory pressures (PIP) and positive-end expiratory pressures (PEEP) to a set range of values. All of this in one device with no need for an oxygen reservoir. This is smarter CPR.
