Airon pNeuton A, Operator'S Manual

Page: 8 / 64

pNeuton Ventilator 2 - 2
The Operational Verification tests as described in this
manual (Section 4) must be performed prior to connecting
a patient to the ventilator. If the ventilator fails any of the
tests it must be removed from clinical use.
DO NOT return
the unit to clinical use until all repairs has been completed
by an Airon approved repair facility and all operational
verification tests are acceptable.
The pNeuton Ventilator has been designed for use on
adult and pediatric patients. The pNeuton cannot deliver
operator adjusted tidal volumes less than 360 ml. DO NOT
use the pNeuton Ventilator on neonatal or infant
patients, or small children.
To protect the patient from high airway pressures, insure
that the Peak Pressure control is adjusted appropriately.
Due to the design of the ventilator (see Section 7 -
Theory of Operation) the Tidal Volume and Respiratory
Rate controls are interdependent. The Tidal Volume
control is a calibrated control. The Respiratory Rate
control is calibrated for a set tidal volume between 500 ml
and 900 ml. Lower tidal volumes will have higher rates,
higher tidal volume will have lower rates. Once the tidal
volume is set, it will not vary as the respiratory rate is
changed.
However, if the Tidal Volume control setting
is changed the respiratory rate may change. Always
recheck the patient's mandatory breath rate after changing
the tidal volume to assure the patient is receiving the
proper respiratory rate.
The pNeuton Ventilator is not intended for use under
hyperbaric pressure conditions. If used in these conditions
tidal volume delivery will significantly decrease. Careful
patient monitoring of tidal volume with a hyperbaric
compatible external spirometer is mandatory.
