1 - DESCRIPTION OF THE PRODUCT

Bronchial provocation tests (BPTs) are an important diagnostic aid

in the study of bronchial hyper-reactivity states, particularly in determining the etiopathogenesis of asthmatic expressions.

This is an experimental technique that tends to lead to measurable bronchial obstruction in response to the inhalation of various

substances.

and thus highlighted the existence of various forms of asthma.

An electric signal opens the solenoid valve and allows the air outlet from the nebulizer.

The solution consumption for an established intervention time can

be measured through the nebulizer diagram, depending on the

inhalation time set by the doctor.

QUANTITY DESCRIPTION

$VWXG\RIWKHHIIHFWVRISKDUPDFRORJLFDODJHQWVDQGVSHFL¿FLPmunotherapy in asthmatics examined using this method has led to

a more rational therapeutic protocol for these patients.

BPTs allow experimental reproduction of bronchospastic reactions, and a more accurate analysis of the progression of the crisis

and the pharmacological effect of prevention or resolution. (D’Amato: Allergia respiratoria da pollini e da miceti).

A simple easy-to-use instrument that makes it possible to show the

reactivity threshold due to the dose of a known quantity of inhaled drug

and to standardise factors affecting the dosage is the MB3 Dosimeter.

The Dosimeter MB3 supplies an unique instrument :

• For bronchoprovocation tests: Allergology - Pneumology - Epidemiology - Preventive Medicine

• For nasal provocation tests: Ear nose and throat

6 - PREPARATION OF THE INSTRUMENT

CONNECTION OF THERMISTOR AND MB2 NEBULIZER TO

THE DOSIMETER MB3

a) Connect the thermistor to

the “T” piece of the nebulizer

and the metal plug at the end

of the cable to the “Thermistor

Connector” socket of the unit;

b)

Connect

the

PVC

transparent tubing to the

nebulizer nipple at one end

and to the “Air Socket” of the

unit at the other end.

Dosimeter MB3 operates in two ways:

- by connecting to the compressed air supply system, which must

supply at 3-5 bar;

- with the aid of the internal compressor, which allows autonomous

operation

CONNECTING THE DOSIMETER MB3 TO AN EXTERNAL

MEDICAL COMPRESSED AIR SUPPLY

The point of connection to the

medical compressed air supply is

located on the rear panel of the

device, just above the power socket.

Screw in the connecting pipe to

the medical compressed air intake

sleeve as shown in the figure below.

EMERGENCY MANUAL THERMISTOR

In case that the automatic thermistor functioning by patient’s inhaling

is defected, use the EMERGENCY MANUAL THERMISTOR.

In this case synchronization between inhalation and the start of

nebulization is controlled by the doctor, who tells the patient to

breathe in and presses the button at the same time.

AIR TANK RELEASE

Before starting the testing, press several times “AIR TANK RELEASE” in order to wet well the internal part of the nebulizer.

PRESSURE CONTROL FROM THE MANOMETER

During the inhalation operation, the value of pressure should be of

atm.1,8 ±0,10 atm., corresponding to bar 1,8 ±0,10 bars, which

correspond to psi 25,6 ±1,4 psi.

1 bar = 1 atm=1Kg/cm2

BRITISH PRESSURE UNIT POUND FOR SQUARE INCH : 1 bar

= 14,22 p.s.i.

THERMISTOR SENSITIVITY DIAL

The Thermistor sensitivity dial must be regulated according to the

inhalatory capacity of the patient (High values correspond to a

high thermistor sensitivity due to a low inhalatory capacity of the

patient; low values correspond to low thermistor sensitivity due to

a high inhalatory capacity of the patient).

Before connecting the thermistor to the DOSIMETER MB3, turn the

thermistor sensitivity regulator (15) counterclockwise to the end.

In the case it does not move, it should be unblocked: simply move

the black stop lever behind the knob.

The thermistor sensitivity dial should then be regulated by turning

the knob in the direction of the arrow, until it is automatically activated by the patient when inhaling. The sensitivity of the thermistor sensitivity dial could reach the point of automatic start of the

thermistor and the automatic functioning of MB3 (without patient

actioning it by inhaling).

7 - HOW TO PROGRAMME THE DOSIMETER MB3

When the DOSIMETER MB3 is switched on, the display and the

inhalation time led are illuminated. The unit must be programmed

as follows:

a) Set the INHALATION TIME for each inhalation.

Max. length of time: 9,9 sec.

(Eg. : If the requested aerosol delivery time is 1,3” press keys 1

and 3)

b) Set the PAUSE TIME between two inhalations.

Max. length of pause time : 99,9 sec.

(Eg.: If the requested pause time is 6,5” press keys : 0, 6 and 5).

It is advisable to keep a minimum pause time of at least 3 seconds between one inhalation and the next one.

c) Set the total NUMBER OF INHALATIONS.

Max number of inhalations : 99.

(Eg. : If the requested number of inhalations is 5, press keys: 0

and 5).

d) Once the programme has been set, press ENTER (3) to activate the thermistor.

Keys 5, 7 and 9 serve to check the readings programmed

 (JLI\RXZLVKWRFKHFNWKHQXPEHURILQKDODWLRQVLQWKHSURJUDPPHSUHVVNH\ 

If you need to switch the unit off without cancelling the data previously programmed, switch off the compressor only (“compressor

only on/off switch” on the front panel).

8 - HOW TO CANCEL AND CORRECT THE PROGRAMMED

DATA

Keys 6 “CANCEL INHALATION TIME”, 8 “CANCEL PAUSE TIME”

and 10 “CANCEL INHALATION NUMBER” cancel each of the programmed readings allowing new data to be inserted.

micrograms (mcg) or moles.

So, mg (milligram) is one thousandth of a gram

mcg ( microgram) is one millionth of a gram

mole is the atomic weight of the elements comprising the solution

9 - CALIBRATED NEBULIZERS CONSUMPTION DIAGRAM

Both upper and lower part of every nebulizer supplied with the

DOSIMETER MB3 is numbered.

After cleaning and reassembling, according to the positions indicated by the arrows, a quantity of 3 ml of saline solution is introduced.

7KUHHZHLJKLQJVDUHWKHQHIIHFWHGWKH¿UVWRIZKLFKDIWHUDQHEXOLzation time of 0,5 seconds, the second after 1 second and the third

after 1,5 seconds of nebulization.

Every measurement is repeated four times and the arithmetic

mean of the results of these four measurements is indicated on

the diagram.

All these details transferred on the diagram forms a curve which

indicates what is the nebulization time to be programmed, once

the quantity of buffer solution to be nebulized is known. Each diagram is numbered with the same number of the nebulizer it refers

to: each nebulizer has its own diagram which cannot be used for

any other nebulizer, as it would not be valid.

Here is an example regarding the mole.

If we take distilled water, the chemical formula of which is H2O,

we can calculate how many grams one molecule of distilled water

weighs.

Atomic weight of hydrogen (H) = 1.007

Atomic weight of oxygen (O) = 15.995

Total atomic weight of distilled water =

1.007 + 1.007 + 15.995 = 18.009

So one mole of distilled water weighs 18.009 grams.

Here are some sample conversions.

If we have to administer 33 mcmoles of drug, how many grams

does that correspond to?

Each nebulizer repeats its own results on condition that:

D $IWHUGLVDVVHPEOLQJIRUFOHDQLQJRU¿OOLQJXSLWLVUHDVVHPEOHG

keeping to the parts of the nebulizer with the same numbers

and also paying the due attention to their position so that the

c) Pressure values shown by the manometer are correct when operating;

d) The environmental conditions (temperature and humidity) are

not modifying the nebulization diagram.

Now we can determine how much drug is nebulized. But remember that a puff only partially contains nebulized drug depending on

the percentage of it dissolved in the buffer solution.

10 - HOW TO READ THE CONSUMPTION DIAGRAM

The diagram shows the quantity in milligrams of the solution nebulized from 0 to 1,5 seconds.

The nebulized quantities expressed in milligrams are represented

on the X-axis, whilst the nebulization time expressed in seconds is

shown on the Y-axis.

Example

For the administration of 9 mg of solution please proceed as folORZV

- locate the value of “9” on the x-axis and trace a vertical line from

this point until the characteristic curve is met;

11 - NOTES AND USEFUL ADVICE

When preparing the solution to inhale, the problem is knowing how

much drug is nebulized and the percentage of drug and buffer

solution to prepare.

First of all, remember that the unit of measurement with the Dosimeter is the milligram (mg) whereas drug dosages are expressed in

16

Take the following equation:

1 : 18.009 = 33 x 10-6 : X

18.009 x 33

X = --------------------- = 0.000594297 grams

1,000,000

How to prepare the solution.

If we have to administer 33 mcmoles of drug, what is the percentage in one litre of buffer solution?

First of all we need to know how much drug is nebulized. So take

one of the nebulizers that come with the MB3 Dosimeter and read

the accompanying graph. Be careful not to get it muddled up with

the graphs of the other nebulizers. Let us suppose that the sample graph taken shows a nebulization of 7.5 mg (0.0075 grams) for

an inhalation time of one second.

We have already seen that 33 mcmole corresponds to 0.000594297

grams.

The percentage of drug to dissolve in one litre of buffer solution is

0.000594297

-----------------0.0075

= 0.0792396, rounded up to 0.08, so equal to 8%

We can work backwards as a check.

8% of 7.5 mg is 0.6 mg, which is the quantity of drug present in a

one-second puff using the nebulizer delivering 7.5 mg.

We can convert the 0.6 mg into moles using the simple equation

1 : 18.009 = X : 0.006

0.006

X = --------- = 0.000033316675 = 33.316675 mcmoles

13 - OPERATION

First clean and sterilise the nebulizer.

Then check that the ambient temperature is the

same as the value shown on the graph ±1°C.

After programming the instrument following the

instructions under “How to Program the MB3

Dosimeter”, proceed as follows.

- Make sure the nebulizer is clean after the previous session.

- Pour the drug in from the top or unscrew

the nebulizer anticlockwise and pour the drug

straight in. Then screw the two parts together

as shown by the arrows.

$SSO\WKHQRVHSLHFHRUPRXWKSLHFHDQG¿WWLQJDVUHTXLUHG

- Hold the nebulizer upright.

- Fit the connecting tube onto the air intake on the Dosimeter.

- Connect the thermistor.

- If the appliance is designed for connection to the compressed

air mains, activate the green illuminated switch marked ON/OFF

Unit (Ref. 1).

If you wish the appliance to operate independently, make sure it

is not connected to an external supply in order to prevent stress.

Then activate the green illuminated switch market “ON/OFF Unit”

(Ref. 1) and the black switch marked “ON/OFF for compressor

only” (Ref. 16).

- Regulate the thermistor following the instructions under Adjusting

Thermistor Sensitivity.

- Press the Air Tank Release button for 2 - 3 seconds to wet the

walls of the nebulizer.

- Check that everything is connected properly, otherwise the drug

14 - INHALATION

Sit on a chair in an erect, relaxed position.

Place the mouthpiece between the lips and breathe deeply.

An acoustic signal will sound while the drug is being administered.

It will continue for the set time and then the drug will stop being

administered.

The mouthpiece must be removed as the subject breathes out.

15 - CLEANING

After each treatment a small amount of

medicine remains in the nebulizer. This

contaminates the next treatment. To exclude any danger of infection through

contamination, all components used

must be thoroughly cleaned after each

treatment.

Proceed as follows :

- Detach the connecting tube from the

nebulizer

- Remove the mouthpiece or the nasal

piece

- Remove the thermistor

- Unscrew the upper part by turning it anti-clockwise

5HPRYHWKHEDIÀH

- Wash all the nebulizer components in hot water and a little detergent

- Rinse under running water and allow to drip

- Dry all the components with a clean cloth

- After drying, reassemble the components.

If a small amount of humidity remains in the air tube after each

treatment, the nebulizer should be removed and the dosimeter left

on to allow the ventilation from the compressor to dry the tube.

121 °C for 15 to 30 minutes. Please place the single components of

the nebulizer in the autoclave machine as indicated in the drawing.

- Allow the nebulizer components to cool.

- Dry thoroughly as described under

heading “Cleaning”.

- After drying, reassemble the components.

17 - REPLACEMENT OF THE FUSE

To replace the fuse proceed as follows:

Having disconnected the plug from the wall socket, remove the

fuse-holder located on the back side of the equipment, near to the

socket, using a screw-driver (not supplied with the unit).

Take out and throw away the old safety fuse and replace it with a

is then diluted by preparing different solutions (eg. 20 ml of Carbacholine at 5% pH 5,81 plus tampon solution).

It can thus be used with the Dosimeter in the same way as Methacoline.

As for Methacoline, the following protocol is used in Prof. Mellilo’s

department at the CARDARELLI HOSPITAL of Naples.

Methacoline 5% (50 mg/ml) is obtained by diluting 5 gr of Methacoline in powder, in 100 ml of distilled water.

For the inhalation, 20 ml of Methacoline at 5% is used (pH 4,48)

plus 47 ml of solution “A” (*) plus 34 ml of solution “B” (*) (= 100 ml

of Methacoline 0,1% at pH 7).

It is necessary to follow a correct progression with the doses which

also depends on the calibration of the nebulizers.

It is also necessary to remember that the dose is accumulative.

(*) = Solution “A” comes from 8,9 gr of phosphatodisodic plus 500

ml of distilled water.

Solution “B” comes from 6,9 gr of phosphatodisodic plus 500 ml

of distilled water.
