This level is then adjusted until the increase work of breathing decreases. Start your CNEP roughly 2cms H2O more than you would CPAP. Used in conditions with increased work of breathing, small airways disease, V/Q mismatching and those infants who may tire easily post extubation. Modes of ventilation with BCVContinuous negative pressure (CNEP) SMA, Duchennes, etc.)Head and Spinal InjuriesProblems with Weaning from PPVVentilation during anesthesia in Ear Nose and Throat (ENT) ProceduresCystic Fibrosis (CF), and those who require physiotherapyAids Related Lung DiseaseAsthmaVentilation post-operation (i.e., post-coronary bypass, Fontan/Glenn, post-pneumonectomy) Who would benefit from BCV?Patients with any of the following:Acute Respiratory FailureChronic Obstructive Pulmonary Disease (COPD)Neuromuscular (e.g. Allows patients to eat, drink and talk while fully supported unlike any other form of invasive or non-invasive ventilation.
How the Cuirass (BCV) is differentThe pressure applied within the cuirass acts uniformly over the thorax, thus lung expansion is also uniform, ventilating all areas of the lungs.A negative pressure is generated within the chest cuirass for inspiration or continuous inspiratory assistanceA positive pressure within the cuirass induces expiration, making the Hayek RTX particularly efficient at CO2 clearanceBCV in conjunction with PPV is used as an aid to weaning, to increase right ventricular function and to aid in expansion of areas of collapseNo risk of VAP, barotrauma or infection. These complications, along with those of ventilator associated pneumonia, are of no relevance with biphasic cuirass ventilation (BCV).
Increases in pressures/volumes to aid ventilation of all areas of the lungs leads to barotrauma, volutrauma and possible development of a pnuemothorax. The United Hayek Hayek RTXBiphasic Cuirass Ventilation (BCV) Conventional mechanical ventilationIn positive pressure ventilation (PPV), the gas pushed into the lungs naturally follows the path of least resistance, therefore ventilating the already well ventilated areas.
