When a patient trigger is detected, a Pressure Support patient breath is given.
Apnea Backup ventilation begins when the time since the last breath start is greater than the set Apnea Interval. When Volume is selected, all machine and assist breaths are Volume Control breaths.
Breaths are given according to the Tidal Volume and Insp. Time controls. They are: Variable Controls Controls and alarms that have front panel displays. Buttons Push buttons that select an option or perform a function. Set Value Knob Used to set control values and navigate extended features menus.
Push the button to activate the feature or change the feature state. A green LED next to the button indicates when a feature is on. All other displays will be dimmed.
Page Flashing Controls Flashing Controls Variable controls and alarms will be displayed solid or flashing. Page Control Locking Control Locking The front panel controls may be locked so that settings cannot be accidentally changed. Page Breath Rate Breath Rate Use the Breath Rate control to establish the minimum rate of machine or assist breaths that the ventilator will deliver per minute. Two different levels of difficulty can be set for control unlocking: Easy and Hard. Easy unlocking is the default and this setting is changed using the Extended Features menus.
The Insp. Time setting, along with the Volume control setting are used to determine the peak flow for Volume controlled breaths. While the Inspiratory Time is being updated, the Calculated Peak Flow will be displayed in the display window.
The exhaled Minute Volume is recalculated after every breath. The Low Pressure alarm establishes the minimum expected circuit pressure for the selected breath types. Oxygen from the low pressure source is mixed with air inside the ventilator.
The O percent delivered to the patient is determined by the O inlet flow and the total minute volume and is not regulated by the ventilator. Page 65 Low Pressure O Source cont. Page 67 Low Pressure O Source cont. The breath will be a Volume Control or Pressure Control breath as defined by the current ventilator settings. To deliver a Manual breath: 1 Push the Manual Breath button. The ventilator will operate on external power if it is available, or internal battery, if there is no external power or the external power source is depleted.
Inspiratory flow for Pressure Support and Spontaneous breaths is controlled to meet the patient demand. Page Select Select Use this button to change the monitor in the display window and to select items in the Extended Feature menus. Monitored Data: The monitored data displays may be automatically or manually scrolled.

Page Silence Reset Silence Reset Use this button to silence an alarm for 60 seconds, to reset an alarm, to start a 60 second preemptive silence period, and to permanently silence the Vent Inop and Standby alarms.
Page Tidal Volume Tidal Volume Use the Tidal Volume control to establish the volume of gas which the ventilator will produce and deliver during Volume Controlled breaths. Flow is delivered in a taper waveform over the set Inspiratory Time. The peak flow is calculated based on the Tidal Volume and Inspiratory Time with a maximum flow of lpm and a minimum flow of 10 lpm. To toggle between the modes: 1 Push the mode button once.
The associated LED will flash for 5 seconds. The ventilator will begin operating in the new mode as soon as the mode change is complete.
Page Battery Level Battery Level The Battery Level indicator shows the level of available internal battery power while running from the internal battery. When the ventilator is running from an external power source, the Battery Level indicator is off. When running from the internal battery at the nominal settings shown below, the indicator shows the following levels: Approximate Battery Time Alarm The approximate times shown here are based on tests using the nominal settings, a new battery and a full 8- hour charge cycle as specified in Appendix A - Ventilator Specifications.
This LED is on when the ventilator is supplied with external power and the internal battery is being charged. Page External Power External Power The External Power indicator shows the level of external power while the ventilator is operating from an external power source.
When the ventilator is running from the internal battery, the External Power indicator is off. When running from external power, the indicator shows the following levels: See Chapter 7 - Battery Level for approximate battery time.
Monitored data is shown in the Display Window and is actively updated whenever alarms and extended features are not displayed. NOTE Some monitored data depends on valid transducer calibrations. Pushing the Select button once while scan is active will halt scanning and the currently displayed data will remain in the display window.
The display is updated in real-time while either setting is being changed. In modes where Vcalc is displayed during Inspiratory Time changes, the display can be toggled between Vcalc and I:E calc using the Select button. Some alarms can reset themselves, for instance, a high pressure alarm that is caused by a cough. Other alarms require some action from the operator and the audible and visual alarms will continue until the problem is corrected. When an Apnea alarm occurs, the ventilator will enter Apnea Backup ventilation mode.
For patient safety, this alarm can only be silenced once for 30 seconds and cannot be silenced preemptively.
After the 30 seconds has elapsed, the alarm cannot be silenced again and will continue to sound and display until an alternate power source is provided or the battery is depleted and the ventilator goes INOP. NOTE When the battery reaches empty, the ventilator may run for approximately 5 minutes before shutdown, based on the nominal settings, a new battery and a full 8 - hour charge cycle as specified in Appendix A - Ventilator Specifications.
Actual run time may be more or less depending on ventilator settings, patient demand, and battery age. The length of time the ventilator will operate on internal power is a function of factors such as settings, charge level and condition or age of the battery; When the operator makes changes to the controls or extended features settings, the ventilator stores the new settings in non-volatile memory. During POST, the ventilator checks the stored settings.
The ventilator detects circuit pressure during the beginning of each inspiration. When this alarm occurs, any inspiration in progress is terminated and the exhalation valve is opened. The turbine is stopped to allow the circuit pressure to evacuate when the high pressure condition persists for more than four times the set inspiratory time or more than 3. When an INOP occurs, the ventilator shuts down and sets the hardware to a safe state so the patient can breathe from room air.
When this happens, default calibration values are used, and although the ventilator will continue to operate, the accuracy of volumes and pressures may be reduced. A NO CAL message is posted in place of affected monitored values when the ventilator is operating without valid transducer calibration data. Use the Ventilator Checkout mode to check for correct operation of the displays and controls and to check the patient circuit for leaks.
The ventilator runs an ongoing set of self-tests to verify that it is operating correctly. If the ventilator detects a condition that makes safe ventilator operation uncertain, it reinitializes itself to allow the more sophisticated Power On Self Tests POST to be performed.
Transducer autozeros are scheduled at periodic intervals during ventilator operation. This allows the ventilator to adjust the zero pressure readings as the ventilator warms up and environmental conditions change.
If an autozero test fails, it will be automatically rescheduled to run again on the next breath. This is an informational message only. The message is displayed at power up, when monitored data is being scrolled automatically, and when no front panel activity is detected for 60 seconds. The message is displayed when monitored data is being scrolled automatically, and when no front panel activity is detected for 60 seconds.

The apnea interval is the maximum time allowed between the beginning of one breath and the beginning of the next breath. Page High F High f Use this menu item to set the high breath rate and time period alarm values.
When the Total Breath Rate f exceeds the set high breath rate and time period alarm values, an audible alarm will be sounded and a flashing HIGH f message will be displayed.
Page Vent Operations Vent Operations Use the Vent Operations menu to set up ventilator controls and options that are not available directly from front panel controls. The rise time profiles are numbered 1 through 9 where 1 is the fastest rise time and 9 is the slowest rise time. Pressure Support breaths are cycled from inspiration to exhalation when the flow reaches the set percentage of the peak flow, or when flow goes below 2 lpm.
Pressure Support Breaths are cycled from inspiration to exhalation if this time is reached before the flow reaches the set percentage of the peak flow. When a breath is cycled based on the time setting, the Pres. When this option is ON, Pressure Control breaths are cycled at the set percentage of the peak flow if it is reached before the set Inspiratory Time elapses.
Page Leak Compensation Leak Compensation Use the Leak Compensation option to enable or disable tracking of the baseline flow to improve triggering when a circuit leak is present. When Leak Compensation is on, the system is gradually adjusted to maintain set sensitivity if the leak is stable and there is no autocycling. The Easy unlocking method should be used when only trained personnel have access to the ventilator. The Hard method should be used when children or others may have access to the ventilator and you want to prevent accidental changes to the control settings.
Page Software Version Software Version Use the Software Version option to verify the software version installed in the ventilator. The software version number is displayed as: VER xx. The home position is displayed as: VHome xxx where xxx is the home position for the valve installed in the ventilator. Page Cylinder Duration cont. Page SBT Operations cont. Page Transducer Autozero Transducer Autozero Use the Transducer Autozero menu to manually schedule transducer autozeros and to view previous autozero results.
Autozeros are automatically scheduled at appropriate intervals during ventilator operation, so manual scheduling of autozeros is not commonly performed, but may occasionally be done. If the results are displayed as FDb xxxx -, the Bi-directional Flow Transducer is not installed on your unit. This value will be approximately 0. Eliminate autocycling by turning the sensitivity off before reviewing this measurement.
