Membrane button functions Alarm Silence: Pressing this button disables the audible portion of an alarm for 60 seconds (± 1 second) or until the ALARM SILENCE button is pressed again. This button is not functional for a VENT INOP alarm. Alarm Reset: Cancels the visual indicator for alarms that are no longer active.
Freeze: The FREEZE button freezes the current screen and suspends real-time update of data until pressed again. When the screen is frozen, you can scroll through displayed waveforms, trends or loops using the Data Dial to move the cursor on screen. Inspiratory Hold: When the INSP HOLD button is pressed and held, once the preset volume of a volume breath has been delivered, the patient is not allowed to exhale for a maximum of 6 seconds. Expiratory Hold: When the EXP HOLD button is pressed and held, at the start of the next breath interval, the ventilator does not allow the patient to inspire or exhale for a maximum of 6 seconds. Manual Breath: Pressing this button during the expiration phase of a breath delivers a single mandatory breath at current ventilator settings. No breath is delivered if the button is pressed during inspiration.
6
Membrane button functions (continued) Synchronized Nebulizer: When an in-line nebulizer is attached and the NEBULIZER button is pressed, the ventilator supplies nebulized gas to the patient at 6 L/min. When nebulization is active, the nebulizer flow is synchronized with the inspiratory phase of each breath and can be adjusted in increments of 1 minute for a maximum of 60 minutes. You may end the nebulization period early by pushing the NEBULIZER button again. Caution: Using the nebulizer may impact patient volumes. During volume control breaths, approximately 50 mL is added to the Tidal Volume for every 0.5 seconds of inspiratory time. If this added volume is undesirable for your patient, adjust the set Tidal Volume appropriately. This added volume also slightly increases the Peak Pressure. Properly set High-Pressure alarms help protect the patient from injury. Backpressure from a nebulizer can reduce nebulizer flow. This backpressure varies depending on the manufacturer and/or brand of nebulizer used. The user should be aware of this and take steps to account for the effect of backpressure. Neither volume nor peak pressure is affected for Pressure Control or Pressure Support breaths. Caution: Use of an external flow meter to power the nebulizer is not recommended.
7
Membrane button functions (continued) O2
100% O2: When this button is pressed, the ventilator increases the oxygen concentration delivered to the patient to 100% for 3 minutes. If the 100%O 2 button is pressed again within the three-minute period, the maneuver is cancelled and the ventilator returns to the prior settings for FiO 2. Panel Lock: The PANEL LOCK button disables all front panel controls except MANUAL BREATH, 100 %O 2, ALARM RESET, ALARM SILENCE, and the PANEL LOCK button. Accept: Accepts data entered into a field on the touch-screen. Cancel: Cancels data entered into a field on the touch-screen. The ventilator continues to ventilate at current settings.

Circuit assembly 1. Carefully seat the rim of the diaphragm on the exhalation valve, and gently press around the rim to ensure it is seated evenly as shown. Use diaphragm #10384 on models 15997, 16257, 16330 and 16186. Use diaphragm #16240 on models 16530, 16531, 16532 and 16600.
2. Line up the fins of the exhalation valve body with the openings in the exhalation valve housing.

3. Rotate clockwise until it clicks into place.
4. Attach the flow sensor with the flow tubes in an upright position.

5. To connect the smart connector for the variable orifice flow sensor, pull back the locking sleeve. Push the locking sleeve into the receptacle, and slide it forward to secure. To remove, repeat these steps in reverse order.

Primary controls Activating a primary control To activate a primary breath control, touch the touch-screen directly over the control. The control highlights (changes color), indicating it is active. To modify the settings for the highlighted control, turn the data dial below the touch-screen. Turning in a clockwise direction increases the selected value; turning counterclockwise decreases it.
Primary breath controls The primary breath controls are operator set controls, which directly affect the way a breath is delivered to your patient. They are displayed along the bottom of the touch-screen. Only the controls that are active in the currently selected mode of ventilation are displayed. Displayed control
