This decreases the pressure below normal atmospheric pressure, causing air to rush in through the nose and mouth and into the lungs. This is termed negative pressure breathing. When we breathe out the muscles relax, the diaphragm moves up and in, and this pushes air out of the lungs.
Biphasic Cuirass Ventilation works in the same manner, sucking the diaphragm down and creating negative pressure in the chest – the Inspiratory Phase.
However, what makes BCV so special is that active phase that uses positive pressure to push air back out of the lungs – the Expiratory Phase.
Biphasic Cuirass Ventilation provides an efficient and effective method of non-invasive external ventilation and is a real alternative to traditional forms of ventilation.
As ventilation is biphasic, it is possible to achieve both higher tidal volumes (negative inspiratory tidal volume and positive expiratory tidal volume) and higher frequencies ranging from 6 to 1200 breaths per minute. All while allowing the user to have proper and complete control over I:E ratio, without having to depend on passive recoil of the patient. Biphasic Cuirass Ventilation has been proven to reduce mortality rates, increase patient comfort, and avoid many of the harmful side-effects associated with other existing forms of ventilation techniques.
You can use BCV in virtually any circumstance where you would use any other form of non-invasive ventilation and, come to think of it, even in most cases where you would use invasive ventilation.
Biphasic Cuirass Ventilation works using a clear plastic shell called a Cuirass. The Cuirass is lightweight and has a foam seal that maintains an airtight fit around the patient. It is very comfortable to wear. It is available in 11 different sizes, ranging from babies to adults. The Cuirass is placed on the patient, and connected to a United Hayek power unit, such as the Hayek RTX or Hayek HRTX.
Biphasic Cuirass Ventilation can be used both in the hospital setting or at home. BCV is ideally suited for use in both acute and chronic, intubated or non-intubated patients.
Biphasic Cuirass Ventilation doesn’t just ventilate fantastically, it’s really, really comfortable too. The seal is made of super soft foam, the Cuirass is very, very light and it’s designed to fit like a glove. And, because United Hayek power units automagically compensate for leaks, the Cuirass doesn’t need to be applied tightly.
Did we mention the seal is hypoallergenic, and it’s disposable too? That means it’s hygenic, which helps to avoid infection, and, of course, it’s latex-free.
United Hayek power units are really advanced. Devices like the Hayek RTX are crammed with the latest technology. It incorporates many modes of ventilation, as well as a dedicated physio mode, which not only helps loosen secretions, it helps eliminate them with its built-in cough mode. Any other ventilators you know of do that?!
You can use Biphasic Cuirass Ventilation with virtually any patient that would otherwise be on either a facemask and, (in most cases) instead of a tracheostomy, as well as a method of weaning from invasive positive pressure ventilation (IPPV).
Other Benefits of the BCV
Recent high profile incidents have raised awareness of the acute problem of treating and dealing with mass casualty situations. One particular issue of great concern is the lack of an adequate way to deal with large groups of people requiring ventilation quickly and effectively.
Increased numbers of people gathering at shopping centres, stadia, public transportation facilities, high rise buildings and office blocks have increased the likelihood of mass casualty situations during accidents in these places. Increased traffic on the road, air, sea and rail has added to the realistic dangers faced by large groups of the public when travelling.
