b-card

Artikelnummer: 6570.01

b-card « Boussignac Cardiac Arrest Resuscitation Device » is a device used for managing cardiorespiratory arrest.
b-card device is a non-invasive open system allowing a continuous insufflation of oxygen during cardio-pulmonary resuscitation (CPR). 
This device works on the principle of a virtual valve generated by the acceleration of a flow of oxygen passing through micro-jets.
The presence of this virtual valve maintains positive intra-thoracic pressure during the thoracic compression phase of chest compressions, and a negative intra-thoracic pressure during the thoracic decompression phase of chest compressions.
Consequently, ventilation and chest compressions are synchronized whether they are carried out manually or mechanically.
The intra-thoracic pressure which is obtained allows preserving the Functional Residual Capacity (FRC), to improve gas exchanges and to reduce the risk of rib and sternum damage. The variations of the intra-thoracic pressure improve venous return and haemodynamics.
b-card is designed to work with a flowrate of oxygen of 15 l/min, regardless of the patient size or pre-existing medical conditions.
When placing b-card, it is not necessary to interrupt chest compressions which have already been started.
