At ResMed, we’re focused on improving patient compliance and providing comfortable, effective therapy. That’s why we continue to develop ventilators around iVAPS algorithms, an innovative technology that adapts to patients, especially those with Chronic Obstructive Pulmonary Disease (COPD). Learn more about COPD.
By targeting alveolar ventilation, iVAPS continually maintains ventilation according to the patient’s metabolic needs, decreasing the risk of over and under-ventilation with changing respiratory rate.
Volume assured pressure support (VAPS) ventilators combine the advantages of pressure-support ventilation, such as patient comfort and patient-ventilator synchrony, with the assurance of a tidal volume target. However, while this enables VAPS modes to meet ventilatory needs, response to respiratory changes is slow. Another limitation of VAPS modes is the enforcement of a mandatory target tidal volume on every breath. Changes in breath rate will still trigger the same tidal volume to be delivered with each breath, which can lead to patient discomfort and sleep disruption.
Data from extensive bench testing against iVAPS ventilators and clinical trials have shown that iVAPS effectively meets patients’ ventilatory needs. It also responds faster to respiratory changes without compromising patient comfort or sleep quality.1,2,3,4
