Manual bag-valve-mask (BVM) resuscitators with a tactile feedback system. Recommended by the AHA to deliver 10 breaths per minute (bpm) of 500–600 mL to a standard adult. When activated, the valve restricts the refill of the bag to ~4 seconds: this provides a patient ~10 bpm, helping to eliminate hyperventilation. When the valve is activated, press thumb and 3 fingers simultaneously utilizing the finger ridges to deliver approximately 500–600 mL to patient. Additionally, the BVM is smaller (1200 mL) than most adult bags on the market, which helps to reduce the risk of hyperinflation or barotrauma. It can be supplied with an optional PEEP valve, filter, and dial manometer.
