TURNING THE VENTILATOR ON AND OFF Turning the Ventilator On 1) Push the On/Standby button. If the Patient Query feature is enabled/on when the ventilator is powered up, ventilation and alarm activation are suspended and the message SAME PATIENT is displayed. 

To enable the suspended alarms and begin ventilation with the settings in use during the last power cycle, press the Select button while SAME PATIENT is displayed.



To enable the suspended alarms and begin ventilation with Preset values appropriate for a new patient, turn the Set Value knob until NEW PATIENT is displayed and press the Select button. Then turn the Set Value knob until the desired patient type is displayed (INFANT, PEDIATRIC or ADULT) and press the ® ® Select button (see the LTV 1200 or LTV 1150 Operator’s Manual, Chapter 10, for detailed settings and information).

If the Patient Query feature is disabled/off when the ventilator is powered up and passes POST, it will begin ventilation (appropriate alarms enabled) using the settings in use during the last power cycle.

The monitored data is displayed in the following order: Display PIP MAP PEEP f Vte VE

Description Displays the Peak Inspiratory Pressure measured during the inspiratory phase. PIP is not updated for spontaneous breaths. Displays a running average of the airway pressure for the last 60 seconds. Displays the pressure in the airway circuit at the end of exhalation. Displays the breaths per minute and includes all breath types. Displays the exhaled tidal volume as measured at the patient wye. Displays the exhaled tidal volume for the last 60 seconds as calculated from the last 8 breaths.

Description Displays the ratio between measured inspiratory time and measured exhalation time. Both normal and inverse I:E Ratios are displayed. Displays the ratio between the set Breath Rate and Inspiratory Time. The display is updated in real-time while the Breath Rate setting is being changed. Is based on the Tidal Volume and Inspiratory Time settings. Displayed when selected and whenever Tidal Volume or Inspiratory Time is selected for change. Displays the time remaining until the number of minutes preset in the SBT OP, MINUTES menu have elapsed. (Only displayed in the SBT mode of ventilation.) f/Vt is computed every time the Total Breath Rate (f) or Total Minute Volume (VE) is calculated. (Only displayed when SBT mode is selected.)
