What is High Frequency Chest Wall Oscillation (HFCWO)? The problem of clearing the airways of those ill with pulmonary diseases has been a challenge for ages. Typically, coughing to clear obstruction works well for those with normal lung function. However, the immune system and airway mucous clearance mechanisms need to work together to keep our...Read More

How Does BCV Work? Biphasic Cuirass Ventilation (BCV) or continuous negative pressure cuirass ventilation (CNEP), facilitates normative inspiratory pressure(s) that correct FRC loss by moving the proper anatomy (intercostal muscles and diaphragm) into normal physiological position which “holds open” the chest wall and allows for volume loss, the true source of most respiratory impairments to...Read More

Functional residual capacity (FRC) is the volume of air present in the lungs at the end of passive expiration. At FRC, the opposing elastic recoil forces of the lungs and chest wall are in equilibrium and there is no exertion by the diaphragm or other respiratory muscles. FRC is the sum of expiratory reserve volume...Read More
