840 USER INTERFACE WORKSHOP PRESENTED BY LEE FAH HOONG PRINCIPAL TECHNICAL SUPPORT ENGINEER, SEA

WORKSHOP REQUIREMENTS  PB840 Vent  AC  BPS  Inspiratory and Expiratory Filters  Wall Air and Wall Oxygen sources & hoses

CONNECTING THE GAS SOURCES:  Grasp the Oxygen Hose firmly and push the Quick Connect fitting into the Oxygen Outlet:

CONNECT THE PATIENT CIRCUIT, FILTERS & LUNG NOTE: to eliminate leaks , make sure that the barbs of the patient circuit wye fit snuggly in the patient circuit tubing grooves.

THE RIGHT WAY TO POWER UP THE 840:  The 840 should always be powered on with an open circuit. By leaving the Expiratory Bacteria Filter Latch open, you’ve created an open circuit condition . You can also leave the test lung disconnected.

NORMAL OPERATION STARTUP SCREENS  On power up the ventilator runs POST.  Default startup screen is displayed there are no failure conditions  Note what is displayed on the upper screen:  Vent Startup in progress  Circuit type?  Humidification type?  Time and date?  SST & EST overall test result?

“ NORMAL OPERATION” LOWER SCREEN DISPLAY AT START-UP  NOTE: Running EST wipes out the SAME PATIENT settings from the previous setup. In that case, you may only see NEW PATIENT & SST buttons available in normal operation.

IMPROPER 840 START-UP:  For safety , the ventilator issues a Procedure Error Alarm and initiates Safety Ventilation Mode if a patient (or closed circuit condition) is detected before all of the ventilator settings have been entered and confirmed (accepted).  Safety ventilation is an emergency mode of ventilation per the displayed settings.

SAFETY VENTILATION

After POST: 840 generates 10 LPM Flow to check for patient connection. If the measurement circuitry detects the 10 LPM flow, Procedure Error is initiated.

PRIMARY SETTINGS AREA: CONTAINS VENTILATOR SETTINGS DEFINING HOW A BREATH IS DELIVERED TO THE PATIENT. A/C V- TRIG 50 VC 10 365 44 21 RAMP 1. Which button represents how often the vent will deliver a controlled breath? 2. Which button represents how much oxygen is delivered? 3. Which button represents how much volume is delivered? 4. Which button represents how much positive pressure is maintained during exhalation? 5. Which button represents the rate of volume delivery ?

SYMBOLS DEFINITIONS AREA – PRESS THE PEAK FLOW BUTTON TO VIEW ITS NAME: AC 44 10 21 RAMP When a button is pressed, you know it is activated because it changes to an orange color .

CHANGING THE IBW FROM VENT SETUP TOUCH THE IBW BUTTON: Current Vent Settings 110 50 110 50 Sandbox CURRENT SETUP

CHANGING THE IBW FROM VENT SETUP: TURN THE KNOB TO LOWER THE IBW BELOW RECOMMENDED S/W LIMITS: A/C V- TRIG 50 VC 12 400 50 21 0 RAMP Press OK 55 25 & continue to turn the knob.

TOUCH CONTINUE & PRESS THE ACCEPT KEY A/C VC V- TRIG 50 12 400 50 21 0 RAMP 9 20

UPDATED IBW SETTING 9 A/C VC V- TRIG 50 12 400 50 21 0 RAMP Now change the IBW 20 9 Back to 50 kg!

Pressure Control Ventilation 20 Peak Pressure = PEEP + Pi Now change the PC breath type back to VC and PEEP from 10 to 3cmH2O .

ALARM SETUP ICON Ppeak (High circuit pressure limit) – sets the maximum circuit pressure allowed during inspiration

ALARM SETUP ICON fTot (Breath rate) – sets the maximum breath rate limit (may be an VeTot (Minute Volume) – sets indicator of breath the min & max exhaled minute stacking, autocycling or volume for mandatory & patient distress) spontaneous breath types

ALARM SETUP ICON Vte mand (Mandatory exhaled tidal volume limit) – sets the min and max mandatory exhaled tidal volume limit

ALARM SETUP SCREEN Medium urgency alarm High urgency alarm

LAST 200 BREATHS TO HELP CLINICIANS SET APPROPRIATE ALARM LIMITS

TURNING OFF THE 840 ALARMS  Touch the alarm setup icon in the lower screen to activate that screen if it is not already selected.  Turn off all alarms by pressing the gray alarm buttons and turning the knob to raise the upper limit alarms until they read OFF or 100 cmH2O for Ppeak (it’s max setting).  Turn off all the lower limit alarms until they read OFF or 0.050 ml for Vetot (it’s min setting).

WORK?

Oxygen Sensor Calibration  Performed during normal operation when ventilating – should be performed DAILY when in use  When the 100% O2 Cal 2 MIN key is pressed, vent performs a single-point oxygen sensor calibration during the 100% suctioning procedure  Allows you to calibrate the sensor without having to disconnect the patient

CALIBRATE THE OXYGEN SENSOR Press the 100% O2/CAL 2min key on the keyboard to calibrate the Oxygen sensor. Press the More Information icon in the Upper Screen to view the O2 Sensor reading:

UNDERSTANDING THE VT VS VTE RELATIONSHIP  Locate Vt in lower screen and compare to Vte in upper screen Vte Must be +/-10mls +/- 10% of set VtVte = Spirometry = Patient’s Exhaled Tidal Volume  Set Tidal Volume (Vt) 365 mls + 10 mls 375 mls + 36.5 mls (+ 10%) High Limit 411.5 mls  Set Tidal Volume (Vt) 365 mls - 10 mls 355 mls - 36.5 mls (- 10%) Low Limit 318.5 mls

5 CONDITIONS THAT MAY CAUSE THE SPIROMETRY READING TO BE INACCURATE. 1. A leak 2. An obstruction 3. Wrong humidifier type 4. Wrong circuit type 5. A bad Q3 exhalation flow sensor.

Alarm Log Time Scroll Bar & Date Stamps  Can store up to 80 of the most recent events  Tracks PATIENT RELATED ALARMS , Device Alerts, and System Faults such as Low/Loss AC, Low/Loss of O2 and/or Air, Circuit Disconnects, and Occlusions  Completing a new patient setup clears log memory

ALARM LOG The Alarm Log shows  alarm events in order of occurrence, with the most recent event at the top of the list:  Time stamped alarms  Alarm silences  Alarm resets The question mark in a triangle appears if the log contains an event that has/had not been viewed yet.

ALARMS High-urgency alarm indicator ! ! Medium-urgency alarm indicator Low-urgency alarm indicator ! Alarms on the 840 Ventilator System are classified as High , Medium , or Low urgency

SMART ALARMS High Priority Alarm: 5 tones

ALARMS  High urgency- requires immediate attention. Red high urgency !!! indicator flashes rapidly  High urgency audible alarm sounds (5 tones repeated  twice) Upper screen flashes alarm message 

CIRCUIT DISCONNECT ALARM  Press the Alarm Log icon in the upper GUI screen and the Alarm setup icon in the lower GUI screen.  Create a tubing disconnect by removing the test lung from the patient wye.  What urgency alarm is generated?  What is displayed in the upper GUI screen?  Does pressing the Alarm Silence button silence the alarm?  What new entry is in the Alarm Log?  Reconnect the test lung. What happened? Does the Alarm Log reflect the series of events?

SMART ALARMS Medium Priority Alarm: 3 tones
