The L770 series Bag Valve masks feature a 3 foot circuit between the bag and the mask to provide stand off distance between the caregiver and patient. This unique circuit also reduces the disruption to the mask or endotracheal tube that may occur from squeezing or motion. Each BVM also comes with a mask restraint to secure the mask to the patient during stand-off ventilation. The mask restraint and unique bag design allow for manual resuscitation by a single individual. This BVM can be fitted with a standard bacterial exhalation filter. click for larger image of L770
