Due to its effectiveness and adaptability, the non-invasive biphasic cuirass ventilator (BCV) has grown in popularity. All parts of the lungs are ventilated because the pressure inside the cuirass acts uniformly throughout the thorax, causing uniform lung expansion. The chest cavity creates a negative pressure to facilitate inspiration or ongoing inspiratory support. Since expiration is induced by a positive pressure inside the cuirass, the respirator is especially effective at removing CO₂. Right ventricular function is improved, weaning is aided, and areas of collapse are expanded by using BCV in combination with PPV. There is no need for additional sedation or risk of infection, barotrauma, or VAP. Unlike any other invasive or non-invasive ventilation method, it enables patients to eat, drink, and converse while receiving complete support.
