Fisher & Paykel Healthcare have designed a manually operated, gas-powered resuscitator for infants called the Neopuff Infant T-Piece Resuscitator. One can adjust the amount of oxygen the infant receives from 21% to 100%. The Neopuff contains a variable Positive End Expiratory Pressure valve (PPEP), Peak Inspiratory Pressure (PIP) control and a manometer. It provides more consistent and reliable PIP and PEEP to infants than self-inflating devices and flow inflating bags. The Neopuff allows maintenance of an adequate airway seal while sustaining predetermined levels of PIP and PEEP. The advantage of the Neopuff can maintain pressure for longer period, requires only one hand, and allows the operator to focus on the infant instead of the resuscitation device.
