    filling of the »slow« alveoli is only marginally improved. In Evita 4, the sigh operates during expiration with an intermittent PEEP for two ventilation strokes every 3 minutes. The average airway pressure is higher, and a longer filling time is normally available.

  • Page 159: Simv

    Since the synchronisation of the mandatory ventilation stroke reduces the effective SIMV time, which would result in an undesirable increase in effective IMV frequency, Evita 4 prolongs the subsequent breathing time by the missing time difference ∆T. thus preventing an increase in SIMV frequency.

  • Page 161: Bipap

    Description Ventilation Modes BIPAP Biphasic Positive Airway Pressure The BIPAP ventilation mode is a pressure/time-cycled ventilation mode in which the patient can always breathe spontaneously. BIPAP is therefore often described as a time- cycled alternation between two CPAP levels.* The time-cycled change of pressure gives controlled ventilation, which corresponds to pressure-controlled ventilation PCV.

    BIPAP stroke BIPAP stroke breathing and expiration times are cal-culated by Evita 4 and displayed in the lower half of the screen below the curve setting. The lower pressure level is set with the PEEP parameter, while the upper level is set with P .

    T . For very short expiration times high , Evita 4 switches to a low pressure level P . The normal lung areas are emptied, but the "slow" lung areas only change volume to a lesser extent.* In this way, the ventilation/perfusion ratio can be improved for patients with a poor gas exchange.

    To minimise the deviation from the set O concentration, Evita 4 uses a mixed gas to drive the medicament nebuliser. In adult ventilation, this mixed gas is generated by switching over between compressed gases (medical air and oxygen) in synchronisation with inspiration.
