|The Oxylator® EM-100
The Oxylator® EM-100 is a pressurized respirator which can
double as an O2 inhaler, to replace the commonly
used AMBU self-inflating bag, or the Water-set (with a minimum
gas flow of 10 litres). The Oxylator® EM-100, which is made
from Acetal plastic, is extremely easy to handle, due to its
weight (500 g), diameter (57 mm) and height (108 mm). It has
a residual volume t1 of 20 ml and a maximum inspiration flow
of 40 L/minute. The automatic setting of the respirator yields
a Respired Volume of 12 to 16 L per minute. The inspiration-expiration
ratio (I:E) ranges from 1:1 to 1:2. The automatic setting also
yields a Positive End Expiratory Pressure (PEEP) of 2 to 4 cmH2O.
The system is driven by O2 with a pressure of 3.0
to 5.5 bar at a continuous minimum flow rate of 100 L per minute.
The oxygen coupling meets standard DISS and ISO requirements
and is fitted with a rapid coupling. The Oxylator® EM-100
has been designed to apply artificial respiration to patients
with little or no breathing function, under emergency conditions.
The body weight of patients should be no less than 10 kg. The
integrated coupling, with an internal diameter of 15 mm and
an external diameter of 22 mm, can be attached to either a mask
or an endotracheal tube. Respiration can be done either by hand
or automatically, by depressing and/or adjusting the gold-coloured
inhalation switch on the Oxylator® EM-100. The maximum inspiratory
pressure can also be adjusted over a range of 25-50 cmH20.
The Oxylator® EM-100 can also be used as an inhaler in patients
who breathe spontaneously; in that case, the air to be inhaled
can be enriched with 0 to 15 L O2 per minute. In
case of airway obstruction, the Oxylator® EM-100 emits a
fast clicking sound (main valve).
Operation of the Oxylator® EM-100 is not affected by extreme
