Manually-activated
Cycle for Non-breathing Patient
Manual
Mode. Plots of flow (lower) and airway pressure
(upper) against time for one cycle. The mode is simulated
on an adult lung. The inhalator button is closed off
so that there is no flow in the system. No noise or
flow should emanate from the EM-100. Depress the O 2
button and the airway pressure increases from a baseline
airway pressure (PAW) of zero up to the preset pressure
chosen on the EM-100 (in this case 28 cmH 2O)
as long as the O 2 button remains firmly depressed.
Once the airway pressure reaches the preset limit chosen,
the EM-100 shuts of the flow which is associated with
a loud click. Let the O 2 button go and the
airway pressure will fall rapidly. An I:E ratio of approximately
1:1 is attained. If you do not let the button go, the
airway pressure will fall more slowly as if the unit
was engaged in automatic
or continuous cycling modeAutomatic

button is turned off. The action by the operator is
the same as in manual

An I:E ratio of approximately 1:1 is attained. If
you do not let the button go, the airway pressure
will fall more slowly as if the unit was engaged
in automatic or continuous cycling mode, elongating
the expiratory time. At the end of the E phase a
loud click will alert you that the E phase is complete
and that the airway pressure has returned to a baseline
airway pressure of zero. Until the O2
button is depressed again, the flow will remain
shut off and the airway pressure will remain at
zero. Start a new cycle if you desire. The flow
jumps instantly from zero to just under 40 litres
per minute the moment the O2 button is
depressed. It stays there creating a horizontal
line as long as there is flow, indicating a 'square
wave' or a consistent constant flow until the system
is shut off. The little bump exceeding the horizontal
line at the beginning indicates that the transducers
of the lung simulator cannot electronically measure
the initial burst of flow accurately.
, with the exception that the O 2 button
has to be continuously depressed or turned to the
'locked in' position. The EM-100 cycles continuously
between the I and E phase with a PEEP of 2-4 cmH 2O
at the end of the E phase. The I:E ratio is from 1:1
to 1:2.
