IV.3. SHELVES
Shelf for monitors.
Shelf for instruments.
Those shelves can be installed in both sides of the unit and its height can be regulated,
using the accessories rail placed on the rear of the column.
IV.4. OTHER OPTIONAL ACCESSORIES
Tray for X-ray cassettes.
Oxygen tent hod with security valve.
Holding assembly for two gas cylinders.
Drawers assembly.
IV.5 PULSEOXIMETRY MODULE.
The NESTOMAT 6050 (6100 Version) is a Neonatal Care Center that noninvasively
and continuously monitors arterial blood oxygen saturation (SaO2) and pulse rate.
SaO
2
and pulse rate information is conveyed both visually and audibly. A custom high
contrast Liquid Crystal Display (LCD) with backlighting indicates the SaO
2
, pulse rate,
pulse signal strength and system messages. The tone generator "beeps" with each pulse
beat. The pulse "beep" momentarely changes to a lower tone "beep" when there is a
decrease in SaO
2
.
It has a flexible alarm system with audible and visual indi cators. The high and low
alarm limits are user adjustable. The audible alarm and pulse "beep" volume can be
adjusted or inhibited by the user.
Theory of Operation
The NESTOMAT 6050 (6100 Version) determines SaO
2
and pulse rate
by passing two wavelengths of light, one red and one infrared, through
body tissue to a photodetector. Pulse identification is accomplished by
using plethysmographic techniques, and oxygen saturation measurements
are determined using spectrophotometric oximetry principles. During
measurement, the signal strength resulting from each light source de-
pends on the color and thickness of the body tissue, the sensor placement,
the intensi-ty of light sources and the absorption of the arterial and
venous blood (including the time varying effects of the pulse) in the body
tissues.
The NESTOMAT 6050 (6100 Version) processes these signals, separa-
ting the time invariant parameters (tissue thickness, skin color, light
inten-sity and venous blood) from the time variant parameters (arterial
volume and SaO
2
) to identify the pulse and calculate the oxygen satura-
tion. Oxygen saturation calculations can be performed because blood
saturated with oxygen predictably absorbs less red light than oxygen
depleted blood.
Since measurement of SaO
2
depends on a pulsating vascular bed, any
condition wich restricts blood flow, such as use of a blood pressure cuff
