Why Consider BCV?
Why consider using BCV?
- More natural means of support of ventilation
- No face or nasal mask required
- No trach required
- Can speak with increased volume
- Can continue to eat
- Lungs cleared by support of ventilation
- Chest wall mobility and lung capacity maintained
- Built in HFCWO and cough assistance
The ability to control both phases of respiratory cycle with BCV allows the generation of a beneficial tidal volume and prevents breath-stacking, while providing required minute volume supplementation to meet CO2 clearance needs
Decreased Chest Wall Mobility with Inability to Inspire Deeply
During BCV’s negative (inspiratory) phase, air is pulled into the lungs in a natural way that causes descent of the diaphragm and expands the ribs while naturally maintaining the normal range of motion of the chest wall.
An automatic, built-in cough assist provides an extra deep inspiration and maximizes that effect while clearing retained secretions.
Cycling the chest wall and the muscles of respiration through the full volume range is thought to have a possible strengthening effect on the muscles of respiration.
Decreased Cough Flow with Inability to Clear Secretions From the Lungs
True High Frequency Chest Wall Oscillation (HFCWO) via the cuirass produces a thinning effect of pulmonary secretions and facilitates the migration of secretions to the large airways for expectoration.
BCV has a cough assistance mode that ends each secretion clearance oscillation cycle by providing a deep breath and a strong cough flow (mimicking a “huff-cough” maneuver), which brings secretions up and out of the airways, fully assisting with the expectoration process, even if the patient cannot provide their own cough effort.
BCV can provide adequate ventilation to reduce retained CO2. There is no mask or trach required. BCV can be used in conjunction with positive pressure ventilation and a tracheostomy.
Loss of Bulbar Function
Once bulbar function symptoms begin to appear, benefits of BCV can still be available to the patient.
For soft tissue upper airway obstruction, low pressure CPAP can offer a means to open airway while BCV will ventilate more comfortably than Mask NIPPV at higher ventilating pressures.
A trach button offers an alternative for free flow during sleep with ability to close off without tracheostomy lumen in airway while awake.
If patient has a tracheostomy, BCV will work with the trach.
If patient does not have a tracheostomy, oral secretion control agents will help prevent saliva accumulation and aspiration. If aspiration should occur, BCV can offer a means to clear aspirate from the airways.
