Respiratory Therapy
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...

Headlines from around the country predict what they are referring to as a “Tri-demic”, a triple threat on our health systems of RSV, Covid-19, and the Flu, and point out that the coming season will be bad for all respiratory related illnesses. Respiratory distress in anyone is highly relatable. Who hasn’t experienced some shortness of...

Oscillate, Expectorate, Ventilate – Repeat  Our cardiopulmonary system has a built-in mechanism that upon sensing mucus production in the lungs, reflexively removes them. That built-in mechanism is often sufficient for individuals with normal lungs that may be infected with an acute infection, however, for those with compromised lungs due to chronic illness, it becomes a...

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...

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...
