CPAP set (masker en vernevelaar)

Beschrijving

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 recruit collapsed alveoles
- to restore a satisfactory level of functional residual capacity
- to improve gas exchange at the level of the alveolocapillary membrane
- to decrease pulmonary resistance
- to decrease the work of breathing
- to redistribute the alveolar liquid to the interstitial space in case of acute pulmonary oedema The Boussignac CPAP and its manometer connector is a device for connection to a face mask with its 22 mm male connector, the crenellated upper part remaining open to the air.

This device comprises 2 lateral ports :
- the upper port is preconnected to a an extension tube (length 200 cm) for connection to an air or oxygen source
- the bottom port (colourless translucent) allows:
. controlling pressure (use manometer code 527.01)
. an additional oxygen supply if the gas administered to the patient via the upper port is air
. CO2 monitoring

Contents: 
- 1 CPAP device and manometer connector 
- 1 nebulizer 
- 1 face mask (4 sizes)
Code 5571.303 (adolescent)
Code 5571.403 (adult – small)
Code 5571.503 (adult – medium)
Code 5571.603 (adult – large)

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.

In case of the patient needs any administration of nebulized drug, the nebulizer can be positionned between the face mask and the Boussignac CPAP device.
