Vyaire Avea Operation & User’s Manual

22, 20 Advanced mechanics Compliance Rapid shallow breathing index (f/ Vt): This index indicates the spontaneous breath rate per tidal volume, based on the formula: f/Vt = f 2 /Ve f = spontaneous breath rate (BPM) Ve = spontaneous minute ventilation in L/min Range: 0 to 500 b 2 /min/…

34, 32 Work of breathing (continued) Work of the lung (WOBlung): The calculation using Pes when PEEPes is greater than Pes, indicating patient eort. Work of the chest wall (WOBcw) for a spontaneously breathing patient is calculated using only the portion of the total tidal volume …

4, 2 MIP/P 100 Maneuver screen Controls Duration: This control determines the maximum time the maneuver will last. Normal ventilation suspends and resumes after the set time has elapsed. Range: 5 to 30 sec Default: 10 sec Maximum Inspiratory Pressure (MIP): The P 100 maneuve…

32, Vyaire Avea 30 Work of breathing Ventilator work of breathing (WOBv): This equation calculates the summation of Paw minus baseline airway pressure (PEEPaw) multiplied by the change in tidal volume to patient (∆V) during inspiration and normalized to total inspiratory tidal volume (Vti). If Paw = PEE…

30, 28 AutoPEEP AutoPEEPes: AutoPEEPes measures the dierence between the Pes measured at the end of exhalation (PEEPes), minus the Pes measured at the start of a patient-initiated breath (Pes start) and the sensitivity of the ventilator’s demand system. The sensitivity of the ventilat…

19, 17 Tracheal catheter Placement Some advanced mechanics measurements on the Avea ventilator require a tracheal catheter. To ensure the accuracy of measurements and minimize risk, place the tracheal catheter in the ET tube, and should not extend beyond the tip of the tube. A� The length …
