2.4.1 Operating environmental limits: -18 to +50 degrees Celsius, at 0 to 95 % non-condensing
humidity.
2.4.2 Storage environmental limits: -40 to +60 degrees Celsius, at 0 to 95 % non-condensing
humidity.
2.4.3 The
microVENT
is an automatic time cycled resuscitator. It is also a manually controlled gas
powered device and when manually controlled the tidal volume and frequency are controlled
directly by the operator. (Note: The
microVENT
UtilityVenT is an automatic only device, the
microVENT
Responder is a gas powered manual operated device – see specification pages
and sales brochures for more details.)
2.4.4 The
microVENT
has a maximum attainable pressure of 45 cm water (4.5 kPa) unless otherwise
specified by customer request. This is controlled by the pressure relief cap (The pressure relief
setting is marked on the pressure relief cap).
2.4.5 Drive gas consumption to operate
microVENT
– Negligible.
2.4.6 Inspiratory resistance without Anti-Air-Entrainment diaphragm <0.5 cm H
2
O (0.05 kPa).
WARNING: Fitting the Anti-Air-Entrainment diaphragm prevents spontaneous inhalation
of atmospheric air through the Microvent. In the event of failure of the oxygen supply this
could result in the patient being unable to breathe through the Microvent.
2.4.7 End-expiratory pressure in normal use is atmospheric pressure.
2.4.8 The
microVENT
is pressure limited by the pressure relief cap which incorporates a calibrated
spring loaded seal underneath the pressure relief cap. When patient airway pressure exceeds
4.5kPa the relief cap diaphragm/seal will lift and will relieve flow and subsequently ensure that
patient airway pressure does not exceed the stated value.
2.4.9 Tolerances according to ISO10651-5:2006. The accuracy of specified ventilation parameters
and all other performance related parameters are within the tolerance of +/-10% of the stated
nominal value.
2.4.10 The
delivered volume
or
minute volume
and oxygen concentrations are not affected by
pressure at the
patient connection
unless the patient airway pressure exceeds 45cm H2O
(4.5kPa) at which point the pressure relief valve within the pressure relief cap will operate.
2.4 HOW TO READ AND UNDERSTAND THE MICROVENT SERIAL NO.
2.5.1 Serial number can be found on the underside of the
microVENT
, next to the manual
trigger.
Example
M V R
0 1 1 2
5 5 5 5 5
The first
letters
refer to the type of
microVENT
.
The next four
numbers
refer to the month and year of
manufacture, in the example January (01) 2012 (12). The last five
numbers
refer to the production
number of the unit. When communicating about your
microVENT
please quote the serial number in full.
