FOUR MODES OF OPERATION OF THE OXYLATOR EM-100
--------------------------------------------------------------------------------------
1. MANUALLY ACTIVATED CYCLE FOR NON BREATHING PATIENT -
The inhalator knob (13) is closed. Inspiratory flow can be initiated for a single
cycle by depressing the oxygen release button (1) and holding it down until the
®
OXYLATOR EM-100 releases at the end of the inspiratory phase, or until
chest expansion is considered sufficient for adequate ventilatory exchange and
the oxygen release button (1) is let go. Passive exhalation will then take place.
The inspiratory phase should be restricted to 2 seconds in an adult and 1 second
in a child. The level of pressure release is set by rotating the pressure release
selector (10) to the desired value. A new inspiratory cycle can then be initiated
by depressing the oxygen release button (1) once again upon completion of
exhalation. This mode will not maintain a baseline pressure (PEEP) and
upon complete exhalation the airway pressure will be at 0 cm H O. The
2
®
OXYLATOR EM-100 will cycle as in "continuous mode" if the oxygen
release button (1) is held depressed constantly as in mode 2.
2. CONTINUOUS CYCLE WITH BASELINE PRESSURE (PEEP) FOR
NON BREATHING PATIENT - (should only be engaged when the inspi-
ratory time does not exceed 2 seconds in an adult or 1 second in a child)
The inhalator knob (13) is closed. The system will cycle continuously when the
oxygen release button (1) is either continually depressed or held down and then
rotated clockwise to seal and activate oxygen flow. This function overrides the
®
inhalation mode automatically. The OXYLATOR EM-100 will cycle from an
inspiratory to expiratory cycle maintaining positive airway pressure throughout
the cycle with a baseline pressure (PEEP) value of 2 to 4 cm H O. The system
2
will end the inspiratory cycle upon reaching the preset maximum airway pressure
level indicated by the pressure release selector (10). This allows unassisted pas-
sive exhalation to take place until the expiratory flow diminishes to a level of 2
®
to 4 cm H O PEEP. Then, OXYLATOR EM-100 will automatically start a
2
new inspiratory cycle. When an operator observes an abnormally long inspiratory
phase (greater than 2 seconds in an adult or greater than 1 second in a child), the
®
OXYLATOR EM-100 should only be used in manually activated cycles.
See mode 1.
3. MANUALLY ACTIVATED CYCLE WITH BASELINE PRESSURE (PEEP)
FOR NON BREATHING PATIENT - system will maintain a baseline pressure
(PEEP) if the inhalator knob (13) is opened counter-clockwise and the
®
OXYLATOR EM-100 is operated as in mode 1. This will provide a baseline
pressure (PEEP) of 2 to 4 cm H O.

4. INHALATION OF OXYGEN ENRICHED AMBIENT AIR FOR BREATH-
ING PATIENT - system can be used in this mode by rotating the inhalator knob
(13) counter-clockwise which will allow the air to be enriched with oxygen as
a patient breathes on his/her own. The oxygen release button (1) cannot be in a
depressed position in the inhalation mode.
