I. DESCRIPTION
The NESTORET Incubators are designed for the hospital where isolation of the
newborn is a prime objective. All surfaces are easily accessible for cleaning.
The incubator consists of a transparent hood mounted on a body unit wich contains a
heating pack, a heat circulation system, a humidity system, an air filter unit and an
infant bed wich is adjustable for Trendelenburg, Fowler and Examination positions.
With the front door open, the bed slides out for examination procedures without
becoming disengaged or falling. For such purpose, place the bed on up position by
rotating backwards the two tilting knobs located at both sides of the Incubator base,
then slides the bed out gently until it stops, its security design will avoid to fall.
A cabinet, mounted on casters and having storage space for accessories (except the
BASIC Version), supports the incubator. The incubator includes an I.V. stand.
I.1 HOOD
Transparent, incorporates six hand hole ports, thermometer and a front opening door.
The six hand hole ports have soft
selfadjusting plastic sleeves (optional)
wich are protected from room
contamination by elbow opening clear
molded doors.
The fold-down front door permits
maximum access to the infant when in-
hood procedures are required.
I.2 HUMIDITY SYSTEM
The humidity system consists of a "Water Fill & Drain" unit, a humidity control knob,
a water reservoir, and a connecting rubber tube.
The "Water Fill & Drain" unit, which is mounted in the left side of the incubator, is
made of translucent plastic so the water level in the incubator is visible at all times.
The humidity control knob is mounted on the left side of the incubator.
The rubber tubing in the humidity systemis made of silicone rubber and is autoclavable.
The humidity reservoir and cover are easily removed from the incubator, and can be
autoclaved.
I.3 FILTER UNIT
The filter unit consists of filter pads, cover and oxygen inlets.
The filter housing incorporates the 35% oxygen limiting inlet.
The filter consists of three pads and will remove all air-borne particles.
The cover enables the operator to visually inspect the filter.

I.4 CABINET
Its compartments enables the storage of accessories, etc. Only the BASIC Version has
no storage capability.
Foot brakes are provided on the two front casters in order to lock the wheels.
I.5 IV STAND
Mounted at the left on the rear side, its height is adjustable.

II.1 HUMIDITY CONTROL
The humidity control system provides a range of humidities from closed (-) to open (+).
Humidity condensate will depend on the difference in room temperature and incubator
temperature.
Fill to the gauge line (1.2 liters aprox). Set the
humidity control knob to the desired position.
Check water level daily.
To drain the reservoir, pull and, without
pulling, turn right the manifold and drain the
water into a container.

II.2 OXYGEN SYSTEM
There are two inlets provided for controlled
administration of oxygen. A 35% oxygen
limiting inlet and the Up to 100% inlet are
supplied with metal screw-on caps. Both inlets
are located on the filter unit.
Oxygen should be administered using a "BACK PRESSURE COMPENSATED"
flowmeter.
IMPORTANT: ROUTINELY CHECK THE OXYGEN CONCENTRATION IN
THE INCUBATOR.
Tubing from the flowmeter should be connected to the 35% inlet nipple when the
oxygen concentration in the incubator is to be limited to 35%. The 35% inlet will limit
the oxygen concentration in the incubator regardless of the flow. For a fast increase of
the oxygen concentration (up to 35%) in the incubator, flows as high as 20 to 30 l.p.m.
can be used; however, for economy of operation and to obtain concentrations in the

35% range, a flow of 3 l.p.m. is recommended.
When oxygen concentrations above 35% are
required, the tubing from the flowmeter should be
connected to the Up to 100% inlet and the 35% inlet
should be capped. Oxygen administered through this
inlet will produce concentrations in the incubator of
from 40 to Up to 100% depending on the rate of
flow. Oxygen concentrations should be checked and
the flow of oxygen increased or decreased until the
desired concentration has been reached.
When high oxygen concentrations are required, the
following steps should be taken:
• The water reservoir should be filled with water to
the fill line.
• Air filters should be clean.
• the vents on the sides of the hood should be closed.
CAUTION: DO NOT USE CONVENTIONAL OILS AND
GREASES IN OXYGEN SERVICE EQUIPMENT BECAUSE OF
POTENTIAL FIRE HAZARD. USE SPECIAL OXYGEN
SERVICE LUBRICANT.
WARNING: OXYGEN CONCENTRATIONS HIGHER THAN 40% CAN INCREASE
THE RISK OF RETROLENTAL FIBROPLASIA (RETINOPATHY OF PREMATURITY). IT
IS PROBABLE THAT EVEN CONCENTRATIONS OF 40% OXYGEN (FORMERLY
CONSIDERED SAFE) COULD BE DANGEROUS FOR SOME INFANTS.
FLOW SETTING:
Set the flow at the approximate concentration rates stated here below
II.3 FRONT PANEL (DESCRIPTION AND FUNCTIONS)
II.4. HEATING PACK.
IMPORTANT: BEFORE USING THE INCUBATOR WITH A PATIENT, IT IS
3 L P M for concentration of 40 - 50%
5 L P M for concentration of 55 - 65%
10 L P M for concentration of 75 - 85%
