3 DESCRIPTION OF PRODUCT

3.1

Spencer 190 is a breathing control/assistance device, which comprehends some of the emerging trends in the field of automatic respirators.

It is a volumetric device, which electrically controls breathing functions. It can erogate two different concentrations of medical gas by means of just one feeding gas. The

Spencer 190 ventilator is equipped with safety mechanical and electronical devices able to control some of the main breathing parameters.

It is an electronically controlled device and works as a flow intermittent pneumatic unit, time-cycled, able to supply medical gas at two different concentrations with the same

gas energy source.

The device is portable with a 2-hour self-powered electric feeding system: after two hours external power feeding is necessary, this will automatically recharge the internal

system.

It works in three different modes, which can be selected by the user and has a series of luminous signals paired with an acoustic alarm, that allows rapid recognition of

anomalous situations and functioning.

The user interface is in the front control panel realised in abrasive material that is resistant to common medical substances.. The front panel has clear and intuitive graph-

ics and the case sleeve protects the control buttons. On the right hand side there is a flange with connections for the pressurised oxygen and the supply of medical gas for

the patient.

The wide range of volumes and respiratory frequencies of the SPENCER 190 and the monitoring system for patient safety allows for its use with both adult and paediatric

patients.

INTENDED USE

The device substitutes the breathing functions in those patients who are not able to breathe spontaneously (controlled ventilation).

The following list shows the optimal ventilation parameters

Child (over 15Kg) 30-35 breaths per min. 10-15 ml/Kg TVxFR

SAFETY SYSTEMS

The device is provided with the following safety systems:

Mechanical overpressure valve

Maximum limits of device pressure 70mbar.

This value is set up by the manufacturer, by moving the pressure-limit knob the user can set a value up to the maximum threshold.

Spontaneous breathing

When the ventilator is off or gas supplying is interrupted, the patient can breathe spontaneously.

The device is provided with an independent power supply alarm (9V battery). This acoustic and visible alarm signals intermittently the condition of discharged battery.

The said alarm functions even if the switch of the device is turned OFF. This battery needs to be checked periodically.

The device is equipped with an acoustic alarm for absence of medical gas in entry, when it is turned on.

2.4

The device can carry out the following functions:

- substitute the breathing functions in those patients, who do not breathe spontaneously (controlled ventilation)

- assist the breathing functions in those patients whose natural functions are insufficient (assisted ventilation)

- assist those patients whose breathing functions are irregularly altered and anyway insufficient (automatic breathing system)

The passage from one mode to another is managed automatically by the microprocessor when certain situations occur.

The device was designed for use on emergency rescue vehicles (i.e. ambulances, helicopters).

OPERATING INSTRUCTIONS

When turning on the device, the microprocessor, after a quick functional self test, automatically switches the ventilator to the default "controlled" mode and checks the

acoustic alarm inhibiting it for about 30 seconds, detailing any information on the front panel in the dedicated alarm section. Erogation of medical gas to the patient starts

in cycles at regular intervals, in correspondance with the relevant frequency selected by the command. The current volume of mix sent to each breathing act is detected in

the following way: read the set value on the "volume/minute" button and divide it by the set frequency.

At any time the operator can see the situation by observing the luminous writings on the front panel of the device. Particularly the functioning modes are visualised, the

breathing phases, spontaneous inspiration of the patient and any alarm situations. The real pressure of the patient circuit is always monitored by the luminous manovacu-

umeter on the front panel.

For each breathing act, the electronic controlling device sets off a luminous display that visualises, in sync with the real time passing, the various phases of the breathing

act. If the functioning modes set by the electronic controlling device are not adequate for the patient in question when the machine is turned on, then the operator can select

a different mode, using the select buttons on the front panel.

The different functioning modes are described in the next paragraph.

For the duration of functioning, the microprocessor regulates the cyclical erogation of medical gas and verifies the state of some parameters of breathing, moreover it sig-

nals the exceeding of safety limits activating, depending on the case, the acoustic and/or luminous signals.

The device detects the apnoea situation only if "assisted" or "assisted/controlled" mode is selected. Precisely, if in the "assisted/controlled" mode the patient does not show

any spontaneous breathing functions within the lapse of time between the theoretical term of the breathing act, it activates the luminous/acoustic signal of apnoea and com-

mutes automatically to "controlled" (erogation mix at fixed frequency), tuning on the luminous signal of apnoea. Should the patient start to breathe naturally the device will

automatically go back to "assisted/controlled" mode and cancel any alarm signals, which are still active.

5.2

It is absolutely necessary to regulate first the ventilator volume and then pressure, because a late volume regulation (lt/min) would bring to an immediate

change of the pressure limit. After choosing volume ventilation, keep closed with the palm of the hand the exit outlet of the patient valve (where the mask is

normally inserted), then regulate the pressure limit with the apposite knob.

Hyperextend the head and seek, after inserting an oral-pharynx cannula in the patient's mouth following the correct manoeuvre, in order to guarantee clear-

ness of the airways. Place the ventilation mask on the mouth and on the nose of the patient checking the adhesion of the soft part of the mask on the

patient's face for a good holding system. Selection method of the volume/minute knob (through trips) prevents from value changing during functioning, in

case it is accidentally knocked.

In case of intubation, take the ventilation mask off the patient valve, and insert in the free hose the endo-tracheal tube with its connector.

Resistance of the airways due to obstructions or external cardiac massaging does not cause a variation of the respiratory volume frequency. In case of reduction of the

compliance, the ventilator will react with a rise of respiratory pressure at a constant volume.

FUNCTIONING MODES

ASSISTED/CONTROLLED Breathing

Starting from halfway the exhaling phase, breathing extends for the duration of the whole exhaling phase. Any attempt of the patient to inhale sufficient amounts of prod-

uct in this interval determines the start of a new breathing act and the consequent erogation of medical gas flow.

Attempts to inspire effected outside this interval are not accepted: anticipated attempts because they could be caused by transitional situations in the patient circuit and

could simulate voluntary breathing; late attempts as they could not show, since the machine switches automatically to controlled mode if the maximum limiter of wait is

exceeded, thus inhibiting any attempt to inhale except for the final part of the exhaling phase.

In case of exceeded maximum time of wait, the APNOEA situation is signalled visually and acoustically.

The alarm remains active until acceptance on the part of the respirator of an attempted inhalation valid as from the patient or until the alarm cancelling button "RESET

ALARMS" is pressed.

Any time the respirator considers as valid the inhalation attempt of the patient, it is signalled by means of the luminous display "SPONTANEOUS" underneath the graph-

ics of the inhaling phase.

This functioning mode guarantees prompt intervention of the machine in case spontaneous breathing of the patient stops, and allows for an easy adaptation of the

patient in that the breathing frequency can vary up to 50% increasing or decreasing.

NOTE

It is important though that the breathing frequency selected is the closest to the natural breathing of the patient.

In order to make a precise selection, besides the physiological data and direct observation of the patient, it is useful to use the shape of the wave generated every time

the patient breathes in on the functions monitor.

The selection can be considered optimal when it will be able to illuminate completely by means of the wave shape and during a single breathing act, without setting of

the apnoea condition. A wave shape which cannot complete its cycle when turning on the machine means that the frequency value selected is too low. Consequently,

the patient is discomforted and the I/E ratio is altered significantly. In fact, the ratio is calculated at I/E=1/2 and the volume/minute of mix erogated increases proportional-

ly.

Should the apnoea alarm go off, it means that the value of frequency selected is too high and that the patient cannot keep up with the rhythm of the machine.

CONTROLLED Breathing (IPPV)

This functioning mode is selected automatically by the device when it is turned on. It consists in supplying to the patient packets of medical mix regularly at intervals of

standard duration as per the frequency selection.

When operating in this mode, the relationship between the duration of the inhalation phase and the duration of the exhalation phase is constantly 1 to 2.

ASSISTED Breathing (IPPV with TRIGGER)

This functioning mode can be selected by activating the "assisted" button.

This function ensures that flowing volumes are of fixed duration and they are erogated to the patient. These volumes can be set by means of the frequency knob and of

the volume/minute intervals, following the patient's natural breathing rhythm.

The aperture of the inhalation valve is regulated by pressure; it is necessary that the patient creates depression for the breathing flow erogation to start.

The inhaling and exhaling ratio depends on the characteristics of the patient's natural breathing, however can be corrected using the frequency knob, which determines

the duration of the inhaling phase only, in this circumstance.

The duration of the inhaling phase is calculated dividing by 3 the duration of the whole breathing act.

5.3

E.g.: frequency F = 10 acts/min.

inhalation INS = 60 / 3 * F = 2 sec.

F=5 INS=60/3*5=4 sec.

F=20 INS=60/3*20=1 sec.

TRIGGER

The trigger is a special device able to synchronise the insufflation with the beginning of spontaneous inhalation of the patient. The ventilation supporting technique is

normally employed on patients who are able to sustain inhalation work at brief intervals.

The patient's effort to produce spontaneous breathing generates inside the respirator a negative pressure which triggers rapidly the insufflation, thank to the trigger

mechanism.

The effort (or negative pressure) necessary to set off the trigger mechanism can be regulated and increased progressively in order to aid and prompt the patient towards

breathing spontaneously, re-educating and training the breathing muscles.

The range of regulation goes from 0 mbar to -12 mbar.

5.4 END OF USE

After using the device it is necessary to:

· Turn the switch to the OFF position

· Interrupt oxygen supply
