INTRODUCTION

The Newport Breeze Ventilator can be used to ventilate infant,

pediatric or adult patients. It's versatility provides for a safe and

effective use throughout the entire patient range.
This service manual

(Part No. SER150)

contains the necessary

information to enable a

qualified service person

to maintain and

service the

Newport Breeze ventilator. This manual is a companion to

the operating manual

(Part No. OPR150).

Both the operating and
service manuals should be read before any service or repair is
attempted on the Breeze.

Together the manuals will provide the service person with enough

information to operate, maintain and service the Breeze to an
assembly or subassembly level.

We recommend that you do not attempt to make repairs of a complex

nature such as electronic circuit board repairs unless you are a

.fully

qualified service person and possess the appropriate test equipment.

We also recommend that you contact your authorized service

representative or the service department at

NEWPORT MEDICAL

INSTRUMENTS INC.

for circuit board and other complex repairs, as

the

Newport Medical personnel are properly trained and equipped to

provide this service.
If at any time the Breeze cannot be restored to properly operating

condition the unit should be returned to the NMI factory for the service
or repairs as needed.

The material in this manual is organized as follows:

Section One provides a brief description of the

Newport Breeze

Ventilator, options and accessories.

Section Two covers mechanical drawings and parts.
Section Three covers acceptance tests and calibration procedures.

Parts, Accessories and Optional equipment may be ordered by part
number through your local NMI dealer or by contacting NMI customer
service.

NEWPORT VENTILATOR

Fig

1.1

Shows the Newport Breeze Ventilator.

The Breeze may be operated in either Volume limited or Pressure

limited modes.

Volume limited operation has four basic modes:

Assist Control with Sigh (AIC Sigh)
Assist Control

(NC)
Synchronized l ntermittent Mandatory Ventilation (SIMV)
Spontaneous

Pressure limited operation has three basic modes:

Assist Control Plateau

(NC) PLATEAU)

Synchronized

l

ntermittent Mandatory Ventilation
Plateau (SIMV) PLATEAU)
Spontaneous

The manual inflation button will deliver a pressure limited or a volume

limited breath as defined by the ventilator settings.

Pressure Relief Valve

The pressure relief valve (Part No.

POP120A) is shown in Figure 1.2.

The pressure relief valve is located on the back of the unit. It functions

as a mechanical pressure safety device which provides protection for
the patient against high pressure. This is accomplished by bleeding
off gas and limiting pressure in the circuit at a preset pressure. This
setting is achieved by turning the knurled knob on the pressure relief
valve either clockwise or counterclockwise.

(The pressure relief valve is set to

0 cmH2O before being shipped from

the FACTORY.)

Exhalation Valve

The exhalation valve for adults only (Part No.

EXH100A) is shown in

figure

1.3a.

Figure 1.3b shows the exhalation valve assembly for use on neonatal

through adult range of patients.

Exhalation Valve Assembly (Adult)

The exhalation valve is mounted beneath the Breeze in the square
area marked EXH VALVE. The exhalation valve controls the release of
the exhaled gas to the atmosphere. The opening and closing of the
valve is controlled by the pressure in the pneumatic drive line, marked

EXP. OUTLET, located beneath the unit and to the left of the

exhalation valve. The drive

line(EXP. OUTLET) is connected to the

exhalation valve .by means of a tubing.

Water Tra~ Assembly

The water trap assembly (Part No. WR300A) is shown in Figure 1.4. It

is mounted to the air inlet connector of the mixer on the rear of the
unit. The water trap helps reduce condensates and contaminates in

the air supply to the unit.

A

drain valve assembly, located at the

bottom of the water trap is opened by pushing upwards to release

contaminates collected in the bowl. Contaminated air enters the

inside of the microfiber element

(.I micron filter) where condensates

and particles are removed from the air stream. Liquids (oil or water)
collect on the elements outer surface and then fall to the bottom of
the bowl.

1.2

STAND AND POLE ASSEMBLY

The stand and pole assembly (Part No. SPA450A) is shown in Figure

1.5. The ventilator is mounted on the stand and pole assembly and is
secured onto the pole by a knob screw. The base has two locking
casters and three non-locking casters. When the casters are in the
lock position they assist in keeping the unit stationed in one location.

OPTIONAL ACCESSORIES

Auxiliatv Flow Outlet Assemblv

The auxiliary flow outlet assembly (Part No.AXF150A) is an optional

accessory supplied upon request only. This feature allows the user to
obtain gas flow for various needs. Figure 1.6 shows a unit with the
auxiliary flow outlet assembly.

NOTE:

(AXF150A also includes FLOWMETER FLW300P with

nipple

and tubing.)

SECTION TWO

INSTRUMENT DESCRIPTION

2.1

GENERAL

A

simple functional description and principle of operation of the

Newport Breeze is presented in this section.

The function of various

components, different modes and various settings are also explained.

2.2

POWER SOURCE

The ventilator may be powered by an electrical supply of IOOvac,

120vac, 220vac or 240vac

+/-

10% at 47

-

63

Hz, 45W maximum. The
voltage adjustment on the power entry module located at the rear of
the unit must be set for the supply voltage.

2.3

SOLENOIDS AND VALVES

The Newport Breeze has four solenoids and four valves. The solenoids
are electronically controlled and the valves are pneumatically
controlled by the solenoids. The function, switching cycles and control

methods of these components are explained in Table 1 and Table 2.

The reader is advised to refer to pneumatic diagram Figure 2.7.
