VentilO Status

The physiological dead space is calculated according to published formulas linked to the predicted body weight of the patients, the instrumental dead space (linked to the volumes of the endotracheal tubes, connections, heat and moisture exchangers) is calculated. - If one wishes to keep the PaCO2 constant after reduction of the instrumental dead space, it is possible to calculate the possible reduction in tidal volume (and the impact on the alveolar pressures: plateau pressure and driving pressure) or the reduction in respiratory rate.  In addition to the measurements of these different parameters, several educational texts are accessible in the application to understand what dead space is during mechanical ventilation, what is instrumental dead space, what is the impact of dead space in function of ventilation settings and possible gains.  Minute ventilation and alveolar ventilation (minute ventilation - dead space ventilation) are calculated.  (iii) to learn about the impact of dead space on ventilation efficiency.  The initial settings for minute ventilation (tidal volume (VT) and respiratory rate (RR)) will be proposed.  Educational texts are proposed to help other settings (PEEP and FiO2) in the different care contexts.  Optimizing protective ventilation settings is covered in another separate tab.  The this app application was developed with the help of several mechanical ventilation experts. your device.  The VT will be determined according to the predicted body weight, the body temperature and the type of patient (medical or surgical).  These calculations and descriptions concern ventilated adult patients, in the emergency room, intensive care units and in the operating room.  VT/RR combinations for different targets of VT (3 to 10 mL / kg PBW will be provided, settings from 6 to 8 mL/kg PBW will be preferred).  VentilO is available in English (default) and French (when the phone is in French).
