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.

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.

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.
