Why treat with BCV?

Continuous Negative Extra-Thoracic Pressure

By means of the negative pressure generated within the shell, the chest wall is held open, creating pathways for mucus to exit the lungs and recruitment of the alveoli to promote better gas exchange.


Biphasic ventilation utilizes an active expiratory phase, which will then allow the ventilator to have full control of the patient’s breathing. This mode mimics our natural physiology and facilitates the use of our pulmonary musculature during inspiration and expiration to manage carbon dioxide retention without the cardiovascular repercussions associated with positive pressure ventilation.

Respiratory Synchronized

Synchronized utilizes biphasic ventilation as well, however, the patient can control their rate and inspiratory time. Once they initiate a breath, the ventilator is triggered and is then able to provide the pressure support needed to expel carbon dioxide from the lungs.

Secretion Clearance

Chest Physiotherapy that incorporates high frequency chest wall oscillation (HFCWO) to break up the thick secretions and cough assist to mobilize those secretions to the upper airways to be coughed out. Used as a scheduled therapy throughout the day to assist with keeping the lungs clear of secretions.

How Does BCV Impact Patients?

Increased Lung Recruitment

  • BCV works in conjunction with your bodies physiology to naturally fill more of the lung with air

Better Patient Experience

  • By allowing patients to continue to eat and drink, as well as speak to their loved ones, BCV fosters patient independence, and active involvement with their treatment.

Increased Cardiac Output

  • A brief period of cuirass NPV increases cardiac output of patients.
