CPAP set (with mask and harness)

Description

C.P.A.P: Continuous Positive Airway Pressure.
Boussignac C.P.A.P. is  a device providing continuous positive airway pressure.

Boussignac C.P.A.P. is a respiratory assistance device for patients with spontaneous ventilation allowing maintenance in the airways of a pressure greater than atmospheric pressure during the entire respiratory cycle. 
The CPAP mode of ventilation allows:

• To avoid intubation and mechanical ventilation and associated complications (prolonged hospitalization, infections, etc.)
• To allow a safe extubation postoperatively for patients at risk of hypoxemia and thus avoid mechanical ventilation and associated complications
• To contribute to the benefit of weaning from mechanical ventilation and avoid associated complications

The CPAP+ set includes:

• 1 Boussignac CPAP which can be connected to a face mask with its 22mm male connector, the crenellated upper part remaining open to atmospheric air, with an extension tube (200cm) and a manometer connector.
• 1 facial mask with an integrated harness (3 sizes available):

. “Adult-small size” (yellow - code V08776615),
. “Adult-medium size” (green - code V08776606),
. “Adult-large size” (blue - code V08776616).

Features of the device:
This device comprises 2 lateral ports:

•  the upper port is preconnnected to an extension tube (length 200cm) for connection to on air oxygen source,
•  the bottom port (colourless translucent) allows controlling pressure (use manometer code 527.01),
• A connection system preventing any risk of misconnection,
• A "star" shaped tube for oxygen delivery reducing the risk of kinking and the discontinuation of oxygen supply.

How it works: 
The gases administered to the patient (air, air-oxygen mixture or pure oxygen) pass through the extension tube and arrive in a circular chamber where the gases can only escape into the central zone passing through 4 micro-channels. At that moment, the injection speed of the gases is greatly increased. Deflector at the exit site of the micro-channels eject the gases arriving at high speed towards the opposite wall. The collision of gas molecules between themselves generates a turbulence which creates a virtual valve and simultaneously the speed of gases is transformed in pressure. This pressure depends directly on the flowrate: if the flowrate (the amount of gas injected) is increased, the pressure will increase; if the flowrate is decreased, the pressure will decrease.
