director to decide whether to adjust the SAVe II+ tidal volume accordingly.
WARNING:
- If PIP limit is reached, the SAVe II+ will cut the inspiratory phase short and less
TV than indicated will be delivered to the patient. Consider increasing respiratory
rate and decreasing tidal volume.

OMBINATIONS
The SAVe II+ supports minute ventilation up to 12.5 LPM at a fixed I:E ratio of 1:2. The
cells marked “not allowable combinations” are TV and RR combinations that exceed
the pump’s minute ventilation capabilities and therefore are not permitted. If an
operator wanted to change the settings from 600 ml at 20 BPM to 400 ml at 30 BPM
(both of which are permitted) the user would first decrease the TIDAL VOLUME to 400
ml before increasing the RESPIRATORY RATE to 30 BPM. Trying to increase the
RESPIRATORY RATE first is not possible because the device does not support 30
BPM RESPIRATORY RATE at a 600 ml TIDAL VOLUME.
A visual (no audible) MV HIGH alarm indicator will activate if the operator selects a
RR/TV combination that results in minute ventilation >12.5 LPM. If +/- controls appear
to not work, it is likely that the operator has attempted to select a RR/TV combination
that is not supported. AutoMedx recommends that the operators experiment with this
during training so that it does not come as a surprise during actual use.
