Acute Pulmonary Edema (APE) resulting from Congestive Heart Failure (CHF) is the main indication. The emergency team generally encounters 3 problems: (1) collapsed lungs, (2) fluid in the lungs, and (3) good right heart performance. Boussignac CPAP System solves these problems by: alveolar opening, redistribution of plasma into the interstitial tissue, reducing blood return (helping left heart function).

Yes, other indications for CPAP include: bronchopneumonia, atelectasis.

Yes, CPAP has been shown to reduce the need for intubation following surgery by improving oxygenation and reducing atelectasis. The Boussignac CPAP System is the easiest to administer in this scenario.

The Boussignac CPAP System works on the same principle as a turbine engine. Oxygen is forced through a system of micro channels that accelerate the molecules. This accelerated flow meets a deflector that directs the oxygen molecules into a central zone within the device. The turbulence created when the O₂ molecules collide creates a positive pressure.

No, the Boussignac CPAP System is not a venturi system.

The Boussignac CPAP System is the only completely open system available on the market. This eliminates re-breathing, reduces the risk of barotrauma, enables excellent patient tolerance and allows the patient to communicate. This unique open system also allows suction of the oral cavity if required without removing the mask and without altering the CPAP.

The Boussignac CPAP System is the only completely open system. Therefore, when the patient demands a high peak inspiratory flow, this can be accomplished by inhaling through the open Boussignac CPAP System. Other systems are "closed systems" so they need higher flow up to 140L/min. in order to accommodate the patient's needs. The flow from the generator must always exceed the patient's demand.

The chart below gives the approximate CPAP/ PEEP in cmH₂O based on the
flow of O₂.

Based on the CPAP level administered and the corresponding flow rate required using the Boussignac CPAP System, the following chart provides the approximate time that a full cylinder will last:
