MODE Descriptions for the 8500s

PEEP

Control Panel

The Control panel has a permanent display of measured PEEP and a button to actuatethe setting of the desired value.

The display box will have the heading “PEEP” and show the “SET” value.

The default is that PEEP will be at the minimum setting ie. the residual that is < 2 cmH2Ocaused by the bellows assembly. In this default condition or if the Set value is subse-quently set below 3 cmH2O the set value display will show as “OFF”.

The method of control is that the user will rotate the Trak Wheel until the desired display is

highlighted, press the Trak Wheel and then increase the set value by rotating the TrakWheel until the desired value is reached, this is then accepted by a further press of theTrak Wheel.

The range of set values will be 3 to 20 cmH2O. An alarm will be implemented to indicateto the user that the set value has not been maintained. The alarm will activate at ± 50 %of the set value.

Future Improvements

In the 8500s ventilator there is a monitor that measures the fresh gas flow of the anaes-thetic machine. The 10 LPM gas flow from the Flow valves in 1 above is an arbitrary fig-ure that has been arrived at empirically. This flow can be reduced substantially at low freshgas flow rates. It only requires high drive gas flows with high fresh gas flows to maintainPEEP. This could obviously save gas which would be helpful when using cylinders for sup-ply.

Volume Control ventilation (CMV)

Volume Control ventilation is a mechanical mode that delivers a tidal volume set by theuser into the patient tubing. This delivered volume is to be independent of the compressionlosses in the absorber, bellows and associated tubing. It will also be independent of anysmall leaks that may be present. Fresh gas flowing into the breathing system will notcause a permanent change in the delivered volume. If a change in fresh gas flow rate oc-

curs during ventilation the ventilator will re-adjust the delivered tidal volume to be correctwithin the next 4 breaths.

8500s Ventilator Fresh Gas and Compliance Compensation

Fresh Gas

Fresh gas flow adds to the delivered Tidal Volume during the inspiratory period. To com-

t f thi d ti i th d li d l d t b d Thi d ti i

To calculate the effect of Breathing System compliance on the delivered TV it is necessaryto measure what the capacity or compliance of the system is (Cs). This can only be doneby some form of pre-use check procedure. In essence it is necessary to have the ability tofirst of all select “Compliance Compensation” from a menu. It is then necessary to lead theuser through the process of measuring the dead space within the particular breathing sys-tem for that period of use. It is obvious that should the system be re-configured the testwill need to be repeated.

A possible process is to allow the ventilator to prompt the user to :-

1. Reduce the FG flow to minimum (but Allow for it as above)

2. Occlude the catheter mount. This can be a 15 mm male taper on the gas machine.

3. The ventilator then delivers a breath to pressurize the system to 10 cmH2O.

4. The ventilator records the volume required to achieve this pressure and verifies thata leak is not present.

The dead space is now calculated as follows :-

Volume in ml = Dead space compliance Cs

Pressure

This figure is stored until the ventilator is switched off or a re-test is asked for by the user.


8/69


So 735 ml is the actual ventilator output into the breathing circuit to give 500 mL at the

catheter mount.

This figure would have to be recalculated in the light of any fresh gas flow change asabove but would just be a variation on the 735 ml figure.

Pressure Control ventilation (PCV)

Pressure control ventilation is a time cycled mode where the ventilator strives to produce

the user set inspiration pressure for the inspiratory period. To accomplish this goal, the in-spiratory flow rate and pressure are set by the user. To do this, the control that is used forthe Set TV function will be reasigned as “I Flow” and calibrated in LPM. The pressureLimit control becomes the “Set Pressure” control. This allows the user to define the deliv-ered wave form. The default pressure will be 30 cmH2O in both Adult and Paediatricmodes.

Inspiratory Pause

A function that is “Inspiratory Pause” is to be implemented. This option will be available involume and PCV mode such that a pause of 25% of the inspiratory time is used as a Pla-teau before starting the expiratory phase. This means the expiratory time is reduced bythe plateau time. If at all possible the pause or plateau time should be made variable from5 to 60 %. The x % should be displayed on the second row up of the display.

It will also be necessary to define an inspiratory time in which the pressure support is deliv-

ered. In this case the breathing rate and tidal volume are not relevant. The Inspiratoryflow rate will be a fixed value of 40 LPM in Adult and 30 LPM in Paediatric.

The detection of a “Patient Attempt” will be carried out by the control system to aidthe speed of support. A patient attempt will be indicated on screen by the negativeexcursion of the pressure wave form being green rather than blue for the positivephase.

SIMV

This mode is Synchronised Intermittent Mandatory Ventilation. This is an extension of thespontaneous mode in so far as the patient can take breaths on demand with pressure sup-port but some mandatory breaths are included. To achieve this it is necessary to set atidal volume, a breathing rate and all of the features described above for pressure support.To simplify things a little the inspiratory flow rate can be assumed from the TV / Inspiratory

Time set values.

The patient attempt or trigger signal will be used to synchronise the mandatory breaths tothe patients breathing pattern and initiate the pressure supported spontaneous breaths.Thus allowing the patient to establish the breathing rate.

In this way a patient could be breathing at say 12 BPM with the settings such that 4breaths of say 500 ml are mandatory and 8 breaths are taken spontaneously with pressure

t f t 30 H2O b th PEEP l l


10/69


This can be explained as follows :-

1. The frequency control sets up an internal clock tick in the ventilator. The time be-tween clock ticks is the Set breathing period and is equal to a time in seconds of60/frequency in BPM. ie. 4 BPM = 1 tick every 15 seconds

With no patient triggers detected, the ventilator will deliver a mechanical breath atthe start of each respiratory period on the clock tick.

2. Preceding each clock tick is a time window in which the ventilator will be looking

for a patient trigger. If a trigger occurs within the window the patient will be given asynchronised mechanical breath. If it occurs outside the window it will be a sponta-neous or Pressure Supported spontaneous breath depending on the ventilator set-ting.

In practical use of the SIMV mode, the ventilator should first be set at an adequateRATE, TIDAL VOLUME, I:E RATIO, PEEP and PRESSURE LIMIT for controlledventilation, say 600 ml, 12 BPM and 1.5 secs for an adult patient. When patient

trigger signals are being displayed regularly the mandatory rate can be reducedand the total breathing rate will be controlled by the patient. If this rate is inade-quate the the low MV or Rate alarm will be activated.

after one minute and the mains fail alarm activates for a few seconds.

Verify that after one minute of mains failure the mains fail alarm activates again for a few

seconds and the screen backlight goes off. Check the SET UP screen comes on and remains

on until the next alarm sounds.

Reconnect the mains supply and check that the battery on charge indicator turns on and the

mains fail indicator turns off.

5.7 Compliance test

Conect the ventilator using the relevant tubes, occlude the patient airway sensor. Switch the

ventilator on and say yes compliance compensation. Follow the on screen instructions. If the

compliance and leak tests are passed it is unlikely that there are any internal leaks.

5.10 Ventilatory Control Functions

With the correct supply gas (oxygen/air), note the following delivered parameters at the stated

control settings whilst ensuring no pressure limiting occurs: (Patient = 20C+20R, mode = adult

run & min fresh gas.) After changing any settings wait for compliance compensation to come

back on before taking any readings.

6.0 USING THE CALIBRATION ANAYSER

This section is intended to be guide in using the Calibration Analyser with this test procedure.

It should be read in conjunction with the operating manual supplied with the Calibration

Analyser.

6.1 Volume Measurement Correction For volume measurements, the patient circuit is connected as shown in section 6.4, that is,

with compliance connected to the High Flow Outlet of the Calibration Analyser. In this

configuration, all Calibration Analyser volume measurements MUST HAVE A

CORRECTION FIGURE ADDED TO THE INDICATED VALUE.

A simple correction formulae is:

At 500 ml ≈ 25cm H 2O peak pressure ∴ mean pressure ≈ 12.5

Calibration Analyser reads 0.48 Lpm

Actual = (0.48 x (1+0.0125)) = 0.486 Lpm

Where MEAN PRES is the breath mean pressure in cm H2O while there is measurable flow.

This formulae must be applied to ALL the Calibration Analyser volume readings BEFORE


43/69


It is not unusual when measuring volume that the Timeter throws up an error message like

'HELP R' or 'HELP F'. All this means is that the Timeter had difficulty in identifying the start

or end of a breath, possibly due to some pneumatic valve noise or reverse flow through the

Timeter.

If it occurs a lot, it might be because there is a leak in the patient circuit, or the Timeter

needs zeroing, or the patient circuit is moving/vibrating with the breath. These are a fewthings to check before assuming there is anything wrong with the ventilator.

6.2 Timeter Peak Pressure Measurements

If the ventilator has anything more than a few cmH2O of CPAP pressure, the Peak Pressure

function on the Timeter will NOT operate. It will sit there forever showing the last peak

pressure measured.

6.3 Timeter Zeroing and Power Up

When the Timeter is first switched ON, its sensors and electronics will need to be zeroed

before the Function Codes will operate. This is simply done by pressing the Zero button

provided after a Function has been selected and there are NO PNEUMATIC CONNECTIONS

TO THE TIMETER.

Title: B.A.V. POWER SUPPLY PCB DocumentNo:129TP076 Sheet 1 of 5

1.0 OBJECTIVE

To set up and test power supply board 10100076 used with the Blease 8500 Anaesthetic

Ventilator and record a set of test results using 129TC000 Checklist and Calibration Record

2.0 SCOPE

The test procedure should be used with newly manufactured boards. When successfully passedthey can be placed into Blease stock after inspection.

3.0 OVERVIEW

All testing is done with the aid of a test jig (TJ 70), this provides power resistors and switching

that allows the correct test loading to be applied. Five 3½ digit LCD panel meters are also

incorporated into the jig which are connected to the input and output power rails of the PSU

board via its connectors.

The jig also contains a mains transformer and rechargable battery with circuits identical to that

used in an 8500 Anaesthetic Ventilator. Hence any results noted will accurately reflect the

board operation when it is eventually fitted into a ventilator.

Most of the testing uses an external DC variable supply, this avoids the need for a 'Variac' and

also allows current limiting to be used.

WARNING - WHEN POWERING UP A BOARD FOR THE FIRST TIME ALWAYS USE


46/69



4.0 TEST DETAILS

4.1 Equipment

1. TJ 70 - Blease test jig (The jigs are serialised TJ 70A, TJ 70B, etc)

2. Variable DC power supply, 17-30 Vdc @ 2.5 Amp. The supply must have an adjustablecurrent limit of 100 mA to 2.5 Amps.

3. Pair of short 4mm plug to plug leads for external DC supply to jig connection.

4. Miscellaneous short connection leads for attachment of test BAV supply board to jig (6 off).

These will vary according to the issue of board tested.

4.2 Connections and Set up

Connections for the test set up are shown below. (Not to scale)

4.4 Test Limits

These are provided on the Checklist and Calibration Record.

The battery volts for ops. 2, 3 & 4 may fall below the stated limits if the temperature of the

board under test (IC3) rises above 21°C.

For op. 12 the test limits (z+?) are referenced to the noted reading (z) for the unregulatedsupply voltage.

5.0 TEST SCHEDULE

See 4.0 TEST DETAILS for information on the test equipment and its use. Also covered are

connection details, set ups, methods and test limits.

All operations in this section must be done in the order as written.

5.1 Preliminary

The board must NOT be attached to the test jig until operations 1 to 3 below are successfully

completed.

1. Set all Test Jig switches to uppermost toggled position.

2. Set external DC supply to 0 volts with a 100 mA current limit.

3. Perform a visual quality check of the new board assembly. In particular:


48/69



5.3 On Load Volts

Set the external supply current limit to maximum (≥ 2.5 Amp) and then toggle the following

five jig switches to ON:

TOP CHARGE ⋅ +5V LOAD ⋅ +6V LOAD ⋅ FLOW VALVE ⋅ DUMPVALVE

Note the four supply voltages stated. (UNREG +25V = 17.0 Vdc)

5.4 Regulation Volts

Increase the external DC supply voltage until the jig UNREG +25V meter reads 29.0 ± 1 Vdc

and note the four supply voltages again.

5.5 Off/On Check

Toggle the jig PCB MODE switch to OFF for a few seconds and then return to the ON

position.

Apart from the BATT VOLTS supply, verify that the other three supplies turn OFF and are

then restored to there previous value when the PCB MODE switch is turned back ON.

5.6 Battery Operational Check

Toggle the following three jig switches:

BATT to CONNECTED ⋅ BATT RELAY to ON ⋅ +6V SUPPLY to HOLD


49/69



5.11 Mains Operation

Toggle the following three jig switches:

ALARM SOUND to OFF ⋅ +24V RELAY to NORM ⋅ PCB SUPPLY to AC

After toggling the jig PCB MODE switch to ON, verify all supplies are restored to their

nominal ON LOAD values. The BATT VOLTS may be a little low as charging is initiated dueto previous testing.

Verify on the jig that the PCB SUPPLY lamp is similarly illuminated as the adjacent JIG

SUPPLY lamp.

Note - the supply voltage to the board under test as shown on the UNREG +25V meter is

protected by thermistors. These may trip if the board is allowed to run at full load for

any length of time, particularly when running from AC.

To regain normal operation, turn OFF the jig external DC and mains supplies for a

couple of minutes.

5.12 Unregulated Supply

Results for the following are affected by the mains supply voltage which should be at its

nominal value of 240 Vac.
