-
When an operator observes an abnormally long inspiratory phase (greater than 2 seconds in adults and greater than 1 second in a child), the OXYLATOR ® EM-100 should only be used in manual mode and the inspiratory phase restricted to approximately 2 seconds for an adult and 1 second for a child. See page 10, 1.
-
When ventilating an intubated patient, higher pressure release settings may be required. Select a pressure setting of 35 cm H2O to start and adjust if necessary.
-
An audible, rapid clicking sound or buzzing sound and rapid movement of the tip of the main valve indicates airway obstruction. Clear the airway, and then resume the ventilation procedure.
-
The OXYLATOR ® EM-100 should be subjected to high level cold disinfection or boiling water after each patient use.
-
Replace the filter after each patient use and/or if the valve becomes contaminated with vomitus during a CPR attempt.
-

-
If the use or operation of the OXYLATOR ® EM-100 is unclear, contact your dealer or agent for clarification.
-
The OXYLATOR ® EM-100 is a resuscitation management system and should not be used as an unattended automatic ventilator.
-
When several OXYLATOR ® EM-100 are cleaned simultaneously, assure that the serial number on the valve (8) and the pressure release selector (10) match when reassembling the unit. See Section 5, Cleaning and Disinfecting, pages 12 & 13. 5
SECTION 2... TECHNICAL DESCRIPTION AND FEATURES --------------------------------------------------------------Description: The OXYLATOR ® EM-100 is an oxygen powered resuscitator/ inhalator which requires no power source (i.e. battery) other than the supply of compressed oxygen in an appropriate cylinder or wall outlet. The oxygen supply hose of the OXYLATOR ® EM-100 should be connected to its pressurized source supplying a minimum constant flow of 40 litres per minute and between 45 psig to 80 psig or 3.0 bar to 5.5 bar. During the continuous cycling mode, the inspiratory flow of oxygen will be initiated upon complete, continuous depression of the OXYGEN RELEASE BUTTON. A sensing chamber in the OXYLATOR ® EM-100 allows airway pressure to increase to the maximum limit set, at which point the system shuts off the inspiratory flow, allowing passive exhalation to take place. Upon sensing the completion of the exhalation phase, the valve automatically resets and allows the inspiratory flow to start a new cycle. Cycling continues as long as required, provided the OXYLATOR ® EM-100 is connected to pressurized oxygen and its OXYGEN RELEASE BUTTON is continuously, fully depressed. The inhalation mode is activated by rotating the INHALATOR KNOB counterclockwise allowing the oxygen flow to be mixed with ambient air with a patient's own inspiratory effort. The flow in the inhalation mode vents out of the valve and does not subject the patient's airway to any pressurization, permitting patients to breathe unassisted. If a return to automatic cycling mode is needed, full and continuous depression of the OXYGEN RELEASE BUTTON is required. This automatically overrides the inhalation mode. Gauge Port (Optional): A gauge (optional) can be connected to the OXYLATOR ® EM-100 at the gauge port connection (19) to verify pressure readings in the airway. 6

SECTION 3... 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 H2O. The 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 inspiratory 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 H2O. The system will end the inspiratory cycle upon reaching the preset maximum airway pressure level indicated by the pressure release selector (10). This allows unassisted passive exhalation to take place until the expiratory flow diminishes to a level of 2 to 4 cm H2O PEEP. Then, OXYLATOR ® EM-100 will automatically start a 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 H2O.
4.
INHALATION OF OXYGEN ENRICHED AMBIENT AIR FOR BREATHING 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.

SECTION 4... OPERATING INSTRUCTIONS ----------------------------------------The following instructions are for the proper use of the OXYLATOR ® EMX They are to be followed to provide adequate ventilation when attempting Cardiopulmonary Resuscitation. The user of this device must have knowledge of cpr techniques. The instructions deal strictly in the proper use of the device. 1. 2. 3. 4. 5.
6.
The OXYLATOR ® EMX hose must be connected to the available oxygen supply, a wall outlet or a pressurized cylinder. When using a pressurized cylinder, open main valve and ensure regulator indicates a reading of between 40 psig and 80 psig; adjust if necessary. Attach suitable mask or endotracheal tube to patient connection (7), make sure mask is rotated into proper position so that an effective seal can be achieved. Ensure inhalator knob (13) is fully closed, and depress oxygen release button (1) briefly to test for oxygen flow. Rotate maximum airway pressure release selector (10) to desired setting simply by aligning pressure value with the indicator eye (18). The pressure can be adjusted from 20 to 45 cm H2O. It should be initially set at 20 cm H2O and increased if the operator in his or her opinion determines that the patient needs greater airway pressure. When used with an endotracheal tube, select a maximum airway pressure of 30 cm H2O to start, then adjust as required. After positioning person and establishing a proper airway, place mask on person's face so as to achieve a complete seal with one hand; using the other hand, depress oxygen release button (1) completely while maintaining mask seal against the person's face. Hold down oxygen release button (1) FIRMLY, or if appropriate, depress, then turn oxygen release button (1) clockwise for continuous oxygen flow. The unit will start cycling continually. OXYGEN RELEASE BUTTON (1) MUST BE HELD MANUALLY DEPRESSED OR KEPT IN LOCKED-IN POSITION AT ALL TIMES FOR CONTINUOUS CYCLING. CAUTION; WITHOUT A PROPER MASK SEAL THE DEVICE CANNOT CYCLE. A NON-CYCLING DEVICE INDICATES THAT IMPROVEMENT IN AIRWAY MANAGEMENT INCLUDING A PROPER MASK SEAL IS NEEDED.

8.
9. 10.
An audible, rapid "clicking" or buzzing sound indicates airway obstruction, STOP!, take necessary steps to clear airway, then reposition person to continue. REPEAT step # 6. An obstruction is also confirmed by observing the rapid movement of the valve tip (17) of the main valve (8). A natural breathing pattern will ensue as the OXYLATOR ® EMX continually cycles. Ensure that the inspiratory phase does not exceed 2 seconds in an adult or 1 second in a child at any maximum airway pressure setting selected. Switch to manual mode if necessary. see page 10. To stop flow of oxygen, let go of the oxygen release button (1) or, if oxygen release button (1) is in locked-in position, rotate it counter-clockwise. If the OXYLATOR ® EMX stops cycling during continuous cycling, release the OXYGEN RELEASE BUTTON (1) and restart after increasing the pressure by rotating the PRESSURE RELEASE SELECTOR (10) by 5 cm H2O. In some patients, higher cycling pressures are required to overcome increased airway resistance.
