WaterPAP®

Positive Airway Pressure Device

CAUTION: U.S. Federal law restricts this device to sale by or on the order of a licensed physician.

Indications: WaterPAP® is a single patient use positive end expiratory pressure setup for use with infant patients weighing <10 kg in hospital environments to increase end lung pressure above atmospheric in constant flow conditions.

Contraindications: The WaterPAP® device is contraindicated in individuals not requiring elevated lung pressure therapy. WaterPAP® is not intended to be used during Magnetic Resonance Imaging.

Warnings: Positive Airway Pressure (PAP) may have an adverse effect on patient cardiopulmonary status.

  • Always use the corrugated tube with diffuser supplied with WaterPAP®.
  • Always use a pressure gauge to measure the delivered pressure proximal to the patient’s airway.
  • Flow rate increases result in higher then intended pressures being delivered with the use of this device. See FIG below.
This data was generated using a standard 10mm heated ventilator circuit. Results may vary depending on the type and length of the circuit being used.

The graph represents how increasing the flow rate can cause unintended increases in PAP pressures when using the WaterPAP® device with a standard 10mm heated infant breathing circuit.

  • Be advised that excessive pressure may be generated as a result of condensation of water when humidified gas is used.
  • Follow the humidifier instructions with regard to condensation accumulation in the tubing and its affect on pressure.
  • Clinical staff should check infant patient every 2-3 hours.
  • WaterPAP® is intended to be used by medical personnel qualified to manage instrumentation that provide respiratory assistance and or pulmonary ventilation for infants.
  • WaterPAP® is a single patient use device. Do not wash, sterilize or reuse.
Precautions: Use WaterPAP® only at flow rates from 4-12 L/min. The water level may change over time and needs to be monitored to make sure the surface of the water is maintained at the 0 cm level. Evaporation or condensation of water may occur during operation of this device. Changes in water level directly affect the delivered PAP pressures. Always monitor water level and adjust as required. Use only sterile water to fill the WaterPAP® chamber.
