2 Servo i Pocket Guide Servo i

3 Initial set up Servo i

4 Discussion Points Power source Internal drive Setting up a new patient Controls Modes of ventilation Special features Troubleshooting

5 Servo i system and power source Patient unit User interface ICU and in-hospital transport Patient size kg. Pneumatically powered Electronically/ microprocessor control 12v battery if AC fails

6 Internal Mechanism Same as Servo 300 Air and oxygen modules regulate gas flow Expiratory gas passes through the expiratory cassette Moisture trap Ultrasonic flow transducer Expiratory pressure transducer Exhalation valve

7 New Patient Power the ventilator Pre-use check option is offered Check yes or no on the touch screen Evaluates 11 functions Option of enabling tubing compliance compensation Enter patient data Infant versus adult (menu, change pt category)

8 Menu touch pad Controls Measured value boxes atient ategory Text and alarm messages Fixed keys Waveform area Round keys Main rotary dial Direct access knobs Special function

9 Control Areas/Use Select parameters by touching the screen Turn the main rotary dial Press accept Cancel cancels the setting Turning the main rotary dial also selects parameters, by pressing the dial Start/stop ventilation control A stand-by function

10 Control Areas/Use Special function keys Start breath O2 breaths 100% for 1 minute Expiratory hold Inspiratory hold Max 30 seconds

11 Control Areas/Use Fixed keys Alarm silence 2 minutes Alarm profile Shows an alarm screen with alarm limits Used to change alarm limits Trends Records trends in parameters for up to 24 hours Information (I)

12 Control Areas/Use Round keys Main screen access Menu Lists sub-functions not usually changed clinically Quick access Access to scales and loops

13 Control Areas/Use Touch screen controls Patient category Current mode of ventilation Automode on/off (optional) Admit patient/enter data Nebulizer on/off (optional) Optional USN System status (power source)

14 Waveforms Pressure, volume and flow scalars Pressure volume and flow volume loops CO2 monitor (optional)

15 Measured Value Box Values that appear are operator selected Measured or calculated values Depends on patient or hospital need Alarm limits Additional settings All available settings Colors indicate safety levels

16 Parameter controls Select mode Touch screen window appears showing parameters available for that mode Rate Tidal volume PC and PS above PEEP Rise time I:E Pause time O2 concentration sensitivity PEEP expiratory sens. TCT SIMV rate trigger timeout

17 Modes Same as Servo 300 PRVC/SIMV + PSV, BiLevel, NIV To select, press mode pad twice Menu appears Touch desired mode All related parameters appear Select and adjust parameter values

18 Volume control

19 Pressure Control

20 PRVC

21 Pressure Support/CPAP

22 Volume Support VS provides pressure support ventilation with a volume target Flow or pressure triggered Pressure-limited Flow cycled

23 Volume Support

24 SIMV

25 Automode Automode provides PRVC with VS No respiratory effort (12/8/5 secs in adult/pediatric/neonate) Vent delivers PRVC with preset VT and variable PIP up to high pressure limit With respiratory effort Vent switches to VS Breaths are patient triggered (flow or pressure), pressure limited, and flow cycled

26 Automode

27 Bilevel Ventilation

28 NIV

29 Backup Ventilation If apnea time is exceeded Adult seconds Ventilator switched to default settings In VS, switches to VC In PSV, switches to PC I:E 1:2 F = 15 In PC, switches to set PS above PEEP or 20 cm H2O

30 Press Menu to Access Alarms - press 2x to adjust high/low limits Review Compensate tubing compliance Copy Biomed Panel lock (press main screen to unlock) Change patient category (adult or neonate)

31 Troubleshooting Alarms with suggestions
