Capnometry is a method to measure carbon dioxide (CO 2 ) in exhaled gas and it has been used to monitor patient respiratory status. CO 2 monitoring is also used for patients receiving non-invasive positive pressure ventilation (NPPV) therapy during mechanical ventilation. Ventilators actively dilute exhaled gas during non-invasive ventilation. In order to accurately measure end-tidal CO 2 , an adequate amount of expired gas needs to be filled in a CO 2 measurement cell before expiratory positive airway pressure (EPAP) gas from the ventilator arrives to the cell. This is the reason why it is difficult to measure CO 2 stably during non-invasive ventilation using the conventional CO 2 measurement method. Therefore, we developed NPPV cap-ONE mask, which accurately measures CO 2 in exhaled gas during non-invasive ventilation. In this study, we evaluated the basic performance of the NPPV cap-ONE mask system. The NPPV cap-ONE mask system could accurately measure CO 2 in exhaled gas comparing to the conventional device in this study. |
