We have received an increasing number of inquiries related to the exhaled gas on the LifePulse HFJV. Please be advised the LifePulse HFJV utilizes a single-limbed circuit and has unidirectional gas flow, therefore all exhaled gas from the LifePulse HFJV and the conventional ventilator exits via the expiratory limb of the conventional circuit (or alternate CPAP circuit). Filtering of exhaled gases may be accomplished via the use of filters as recommended by the circuit and/or device manufacturer.

The Life Pulse HFV is indicated for use in ventilating critically ill infants with pulmonary interstitial emphysema (PIE). Infants studied ranged in birth weight from 750 to 3,529 grams and in gestational age from 24 to 41 weeks. The Life Pulse High Frequency Ventilator is also indicated for use in ventilating critically ill infants with respiratory distress syndrome (RDS) complicated by pulmonary air leaks who are, in the opinion of their physicians, failing on conventional ventilation. The infants studied ranged in birth weight from 600 to 3,660 grams and in gestational age from 24 to 38 weeks.
