MVP-10 COMPLETE PACKAGE SETUP INSTRUCTIONS
1. If not already done, assemble the stand per the instructions that came with it.
2. If not already done, install the patient connector (white nylon barb) into the brass tee on the back of the ventilator
per the instruction that came with the barb.
3. With the tilt bracket that is on top of the stand facing you, insertan O2cylinder into therings to the right and an air
cylinder into the rings to the left. If necessary, loosen the locking knob and adjust the upper set of rings higher or
lower to properly support the cylinders. It should be approximately in the position shown above.
4. Install the green, O2regulator onto the O2 cylinder and the yellow air regulator onto the air cylinder. Before finally
tightening the regulators on each cylinder, rotate the regulator body so the pressure gauge window is facing up
and the 50 PSI OUT fitting is facing front as shown above. Rotate the cylinders in their brackets so the regulators
are in the final, desired orientation and tighten the two thumbscrews against the cylinders to hold them in place.
5. Place the ventilator into the tilt bracket at the top of the stand. Its angle may be adjusted, if desired, by loosening
the two front screws on top of the stand, adjusting the bracket and then retightening the two screws.
6. Remove the two screws holding the two halves of the blender bracket togetherand separatethetwo halves. Wrap
the two halves around the pole and loosely secure the bracket to the pole below the ventilator using the two
screws. Be sure the two pins in the bracket are towards the bottom so the blender does not fall through the
bracket when installed. Hold the blenderup in front of, but not engaged with the bracket to aidin where you want
the final position of the bracket and blender to be. Once this is determined, secure the bracket in place by
alternately tightening one screw and then the othersowhendone, theyhavebeenequallytightened, evidencedby
somewhat equal gaps between the front and back halves.
7. Place the blender in the bracket. You may have to temporarily remove the ventilator from its bracket to do this.
8. Install the male-to-male coupler into the O2supply fitting on the bottom of the blender. To this coupler, connect
one end of a 2’ O2 supply hose and then connect the other end to the OUT fitting on the O2 regulator.
9. Connect one end of the 2’ air supply hose to the air input on the blender and then connect the other end to the
OUT fitting on the air regulator.
10. Connect the air/ O2wye to one end of the remaining 2’ supply hose. Connect the wye to the air and O2inputs on
the back of the ventilator and the remaining end of the 2’ hose to the fitting on the left side of the blender as
viewed from the front.
11. The two 10’ supply hoses may be connected to their respective regulator input fittings labeled “50 PSIIN”. These
then are used to connect to air and O2wall sources.

WARNINGS
Whenever the MVP10 is connected to a patient, a skilled operator should be present at all
times at the ventilator or within visual or hearing range of the alarm system used with the
MVP10.
High oxygen concentrations may be hazardous to the patient.
If the gas supplyfails, the patient may breathe atmospheric gas through the failsafe valve.
This is only a temporaryemergencymeasure, whichrequireselevated inspiratoryeffort and
should be corrected immediately.
A patient filter should always be used in the patient breathing circuit to prevent cross
contamination. Breathing through the negative pressure relief valve in a contaminated
environment can be hazardous.
Extreme care should be taken to assure that the patient circuit components are connected
correctly. Improper connection can cause malfunction.
A test lung should be ventilated prior to each use to ensure that all modes are functioning
correctly. An external spirometer should be used to verify correct volumes and flow rates.
Always be certain that the PIP Limit is set correctly and is operative even when volume
limiting, to prevent possibleinadvertent administrationof high pressure.Increasedpressure
can be caused by blocked tubes, changes in patient compliance or resistance, or system
malfunction.
Breathing through the negative pressure relief valve requires a greatly increased work of
breathing and only air isprovided. A situation in which the patient is breathing through this
valve should be rectified immediately in order to prevent possible adverse affects to the
patient.
Clean, dry, regulated gas supplies at 50 5 PSI (345 ±34.5 kPa) must be used at all times
or malfunction may result. Note carefully that the logic (power) gassupplyshould be100%
oxygen at all times to give the greatest accuracy of the control settings and to assure the
most trouble-free operation.
If the ventilator is to beused unattended or without remote monitoring, a high/low pressure
alarm must be used at all times with the user within visual and/or audible range of this
alarm.
A TWO-WAY SAFETY RELIEF VALVE is installed internally. This valve opens when
pressure in the hose delivering gas to the patientrisesabove 70cmH2O10cmH2Oorfalls
below -4 cmH2O. Its purpose is to limit maximum circuit pressure and to allow patient
inspiration in the unlikely event of failure of the gas supply. It is meant to allow
spontaneous breathing for a short time only until the operator can respond to the
disconnect alarm and rectify the supply malfunction. In such a situation, its use in a
contaminated environmentcouldbehazardous. TheSAFETYRELIEFVALVEmustnotbe
removed; and must be maintained with its screened port up and unobstructed.

6
Any HUMIDIFIER used with the MVP-10 must be a "flow-through" type having a low
pressure drop. Use of a humidifier with a "bubbler" tube or pressure jet will render the
SAFETY RELIEF VALVE ineffective.
Do not use in an MRIroom unless the MVP-10 has beenbuilt by Bio-Med Devices for such
an environment. This will be indicated by an MR-conditional label on top of the unit and an
“M” at the end of the serial number.
Do not re-use disposable breathing circuits. Re-use of disposable (single-use) breathing
circuits can result in contamination (patient infection) or circuit degradation (circuit can fall
apart, develop holes, or exhibit polymer decay).
A high / low pressure alarm monitor must be used in conjunction with this ventilator. The
high pressure alarm level should never be set above the lowest relief valve setting.
Do not continue using a ventilator which has been significantly impacted or abused.
Volume-limited ventilators should not be used on unattended patients.
CAUTIONS
The BMD MVP-10 Ventilator is intended for use by qualified clinical personnel only. This
Instruction Manual should be read before using the equipment.
Because this is a CE marked device, it must never be modified without prior expressed
written consent from Bio-Med Devices.
As noted later in the text of this Manual, the MVP-10's time cycle settings are affected by
large changes in barometric pressure, flow rates, and gas composition. They are
repeatable, however, within 5% underconstant conditions. As with any ventilator, periodic
blood gas studies should be made to ensure proper levels of ventilation.
Antistatic or electrically conductive hoses or tubing should not be used.

I. GENERAL
A. INTENDED USE
The model MVP-10 Ventilator is for respiratory support of neonatal and pediatric
patients both in hospital and during transport. It is intended primarily for use in all
applications requiring tidal volumes in the range up to 660 milliliters. It may be used
with a wide range of I/E ratios, including inspiratory time greater than expiratory
time.
WARNING: Do not use in an MRI room unless the MVP-10 has been built by Bio-
Med Devices for such an environment. This will be indicated by an MR-conditional
plaque on top of the unit and an “M” at the end of the serial number.
B. MODES OF OPERATION
It is a continuousflow Ventilator which may beused in any of thefollowing operation
modes:
Time cycled, with volume or pressure limitation, with or without Positive End
Expiratory Pressure (PEEP).
-Intermittent Positive Pressure Ventilation (IPPV).
-Intermittent Mandatory Ventilation (IMV).
Continuous Positive Airway Pressure (CPAP).
Continuous Oxygen Administration (COAD) or constant flow.
C. FEATURES
Portable: compact and light weight
May be hand carried or attached to incubator; used without interruption
during transportation; compatible with masks, tents,and endotrachealtubes.
Gas Powered: portable pressurized tank or wall outlet, providing 50 PSI
oxygen or air.
Operable in Hazardous Areas: non-electric, no shock hazard, case
constantly self-purged.
High Reliability: controlled by miniature pneumatic logic elements; fail-safe
maximum pressure limits; negligible frictional wear.
Very low compliance and dead space factors.
Prevention of CO2 build-up by constant flow wash-out.
Readily usable with standard accessory humidifier, oxygen blender, oxygen
analyzer and pressure alarms.

8
D. PERFORMANCE CHARACTERISTICS
Direct control is provided for inspiratory and expiratory times, air and oxygen flow
rates, and maximum pressure and PEEP or CPAP levels within the patient circuit.
Oxygen concentration, respiratory rate, tidal volume, and I/E ratio may also be
controlled.
Oxygen concentration…………... variable, 21% to 100%
Respiratory rate…………………. variable, 0 to 120 breaths/min.
Tidal volume……………………… variable, 0 to over 660 ml.
I/E ratio…………………………… variable
Oxygen concentration is determined by the air and oxygen flow rates indicated by
two front panel meters. Flow rates correspondingto adesired oxygenconcentration
can be determined by use of CHART A. At extremely low flow rates accuracy may
be reduced; for more accuratedetermination an auxiliaryoxygen analyzer shouldbe
used.
Respiratory rate and I/E ratio are determined byINSP. TIME andEXP.TIMEcontrol
settings. These settings are approximate time reference points which are
repeatable within 5%.* For greater accuracy, an external monitoring device maybe
used.
The tidal volume, when operated in a time-cycled mode is the product of total flow
and inspiratory time:
TIDAL VOLUME (ml) = TOTAL FLOW RATE (ml/sec) X INSPIRATORYTIME (sec)
NOTE: Flow rate is not Minute Volume
MINUTE VOLUME = TIDAL VOLUME X RESP. RATE
It should be noted that the PIP and PEEP/CPAP control settings are affected by
flow. When flow is increased, the pressure levels set by these controlswill increase
somewhat. These changes may be noted on the pressure gauge and the settings
readjusted.
*At elevations above sea level, the intervals set by the INSP. TIME and EXP. TIME controls are increased due to lower
barometric pressure. The difference is about 2½% per 1000' of elevation. With an air supply connected to the POWER
OXYGEN inlet fitting, the time intervals are about 10% less than with pure oxygen connected.

II. DESCRIPTION
A. PRINCIPLES OF OPERATION
The MVP-10 Ventilator provides continuous flow that may be time-cycled for
automatic ventilation with either volume or pressure limits, and with or without
Positive End Expiratory Pressure (PEEP). It may also be used without time cycling
to provide continuous flow past the patient at ambient pressure, e.g. Continuous
Oxygen Administration (COAD), or at a positive pressure, e.g. Continuous Positive
Airway Pressure (CPAP).
1. Time-Cycled Modes:
A constant flow is provided past the patientWYE. The expiration valve is cycled so
that it is closedfor a pre-set time, (TI) and opened for a pre-set time, (TE). When it is
opened, gas flows past theWYE at ambient pressure and is vented to atmosphere;
when closed, exhaust to atmosphere is prevented and pressure builds upwithin the
circuit, delivering gas to the patient. Gas flow into the system isessentially constant
since the source pressure (50 PSI) is much greater than the maximum possible
circuit pressure (80 cm H2O, or 1.1 PSI). An example of this use is for
administration of Intermittent Positive Pressure Ventilation (IPPV).
a. Volume-limited:
The pressure developed in the patient's airway depends upon the total
system-patient compliance and the tidal volume being administered. When
the PIP control is set at a pressure above the pressure developed in the
circuit, then the automatic ventilation is volume limited, andaconstantflowis
delivered to the patient. In this condition the tidal volume (Vt) is the product
of the total flow rate (VI) and inspiratory time (TI):
Vt = TI x VI
andminute volume (V) is the product of tidal volume and respiratory rate (f):
V = Vt x f
Should the patient compliance become less or resistance increase, then the
developed pressure could increase up to the PIP setting. At that point, the pressure
in the patient circuit becomes limited and constant. Tidal volume is no longer
delivered to the patient; excess gas is vented to atmosphere.
b. Pressure-limited:
With flow rate and inspiratory time set, the pressure developed in the
patient's airway depends upon the system and patient compliances. This
pressure is limited by the setting of the PIP control. While the expiration
valve is closed, pressure within the circuit builds up to the PIP setting. Atthat
point, the valve acts to allow flow past the WYE to atmosphere, while
maintaining the airway pressure at the PIP setting. During the expiratory
time, the valve is opened.

10
c. Intermittent Mandatory Ventilation (IMV):
Respiratory rate is set to allow one or more voluntary breaths between
machine-controlledbreaths. Withsufficientflow,thepatient'sminutevolume
and the voluntary tidal volumes are not necessarily limited by the machine
parameters. The respiratory rate may be set to support the patient, but less
than the anticipated voluntary respiration rate. The lower respiratory rate is
normally set by increasing the Expiratory Time.
d. Positive End Expiratory Pressure (PEEP):
By use of the PEEP/CPAP control, a pressure may be maintained in the
patient's airway during the expiratory time in any of the above time-cycled
modes (i.e. PEEP), or during a non-cycled mode with continuous flow-past
the patient (i.e. CPAP).
Adjustment of this control places a controlled pressure on the diaphragm of
the expiration valve maintaining the patient circuit at this pressure during the
expiratory time.
2. Non-Cycled Modes:
A constant flow is provided past the patient WYE, without cycling the expiration
valve.
a. Continuous Positive Airway Pressure (CPAP):
A pre-set pressure is maintained across the expiration valve. Continuous
flow is provided past the patient WYE, allowing the patient to inhale from this
flow while maintaining the airway at the pre-set constant positive pressure.
b. Continuous Flow, or Constant Oxygen Administration (COAD):
No pressure is maintained across the open expiration valve (PEEP/CPAP
control fully clockwise), and a continuous flow is provided past the patient
WYE, allowing the patient to inhale from the flow at ambient pressure.
Figure 2 is a flow diagram showing the interconnections within the MVP-10.
The expiration valve is controlled by a pneumatic logic circuit which is
comprised of four (4) (early models had three (3)) miniature diaphragm
devices, four (4) adjustable valves, several fixed flow resistances and aflow
accumulator. The diaphragm device is a gas actuated, double-piloted,
spring-offset, three- way valve. The entire logic circuit is isolated from the
patient circuit by the diaphragm of the expiration valve. Gas flowing into the
logic circuit cannot enter the patient circuit, and the exhalation gas cannot
enter the logic circuit.
A 40-micron filter is incorporated in the input of the logic circuit. The
pneumatic switching elements have a rated life of over one-billion switching
operations, at rated supply pressure.
The logic circuit controls the two time intervals for inspiration and expiration
and controls the pressure in the patient circuit.

The TWO-WAY SAFETY RELIEF VALVE is installed internally. It vents pressures
above 70 cm H2O 10 cm H2O. It also opens at negative pressures below -4 cm
H2O to allow patient inspiration. (If protection at a lower negative pressure is
desired, another more sensitive valve should be added.)
The ADJUSTABLE RELIEF VALVE is installed externally and may be adjusted to
vent pressures between 70 cm H2O 10 cmH2O and 10 cm H2O 5 cmH2O.
*INSP. TIME and EXP. TIME control settings are calibrated at sea level and 20o
C., ATPD, using USP oxygen. Large changes of barometric pressure or altitude
changes, or use of diluted oxygen will affect time calibration; hence, the settings
should be regarded as reference points rather than precise time indicators.
However, time settings are repeatable within 5%. Approach time settings in a
clockwise direction.

III. INSTALLATION CONSIDERATIONS
A. EQUIPMENT REQUIRED
All equipment required for use of the MVP-10 has been supplied with the
instrument, except for the gas supply. No special tools are needed.
It will be convenient to have available a test lung when setting the
ventilator parameters before connecting to a patient. If Bio-Med Devices
Infant Test Lung (BMD #1021) is not available, a simple finger cot may be
attached to the patient WYE or the WYE may be occluded.
B. SUPPLY GAS
The supply gas isnormally a pressurized tank(s) or wall source of medical
or therapy grade oxygen and/or air. The pressurized tanksshouldbefitted
with regulators adjusted to 50 5 PSI (345 ±34.5 kPa).
No flow restrictingdevice (e.g. flowmeter, throttling valve) can be placed in
the supply line. A flow restricting device interferes with the operation of
the pneumatic logic and may render the time-cycling inoperative.
The MVP-10 will operate with a supply pressure outside of the 50 5 PSI
(345 ±34.5 kPa) range, but accuracy of settings may be impaired. In no
case should a supplypressure less than 35 PSI (242 kPa) or over 100 PSI
(690 kPa) be connected to the MVP-10 as it will cause malfunction of the
ventilator.
The operating time that may be expected from common tank sizes with
different flow rates is given in Table B.
C. MOUNTING BRACKET
The supplied mounting bracket may be installed on a column.
D. PATIENT CIRCUIT
The patient circuit supplied with the MVP-10 incorporates approximate
3-foot lengths of tubing between the MVP-10 and (1) thepatientWYE and
(2) the expiration valve.
WARNING: Always use a bacterial filter.
WARNING: Do not re-use disposable breathing circuits
E. OPTIONAL EQUIPMENT
Other standard equipment which may be used with the MVP-10 at the
option of the user include:
Oxygen Blender --connected in the supply line to the POWER OXYGEN
connection,orbothPOWEROXYGENandAIRconnectorsusingBMD"Y"
