System Overview
Intended Use
The Oxinet III system transmits data from the N-395, N-550, N-595, N-560, or
N-600 pulse oximeter to the Central Station for patient monitoring, via a wired or
wireless configuration. The Central Station displays all monitored rooms, relevant
pulse oximeter data, and alarms.
WARNING: The Oxinet III system is a secondary alarm notification system.
It is intended to supplement and not to replace any part of the hospital’s
device monitoring procedures (including procedures regarding bedside pulse
oximeters and responding to beside oximeter alarms). Do not rely on the
Oxinet III system as the sole source of oximeter alarms.
The intended patient population is comprised of adult, pediatric, and neonatal
patients. The intended environments of use are hospitals and hospital-type
facilities. Hospital use typically covers such areas as general care floors, operating
rooms, special procedure areas, and intensive and critical care areas within the
hospital and hospital-type facilities, such as surgicenters, sub-acute centers,
special nursing facilities, and sleep labs, outside of the hospital. The Oxinet III
system is for use by prescription only.

Description
The Oxinet III software collects and distributes time-sensitive oximetry data via
wired or local network wireless technology. Making use of the Intranet’s security
and connectivity standards, the Oxinet III software enables the review and
surveillance of medical device settings and real-time patient data remotely, using
a standard HTML compatible web browser.
The components that make up the wireless and wired systems are listed below.
Wireless Configuration:
• Pulse Oximeter (suitable for use within the patient environment)
• Transmitter (suitable for use within the patient environment)
• Access Point
• Router/Switch
• Central Station (application server)
• Oxinet III Operator’s Manual
• Pager Transmitter (optional)
– Pagers, at least two, if pager option installed
Wired Configuration:
• Pulse Oximeter (suitable for use within the patient environment)
• Communication Server
• Router/Switch
• Central Station (application server)
• Oxinet III Operator’s Manual
• Pager Transmitter (optional)

Each of these systems is discussed in more detail in the following sections.

Service Manual System Overview
Oxinet III 7
Wireless Configuration
In a wireless configuration (Figure 1), each Pulse Oximeter is connected to a
Transmitter. Each Transmitter communicates wirelessly with an Access Point,
which is connected through a Router/Switch to the Central Station (application
server), where the patient’s data may be monitored. The Central Station can be
connected to an optional Pager Transmitter: if pagers are assigned to a patient,
alarms are transmitted from the oximeter to the Central Station, then through the
Pager Transmitter to the assigned pagers.
Figure 1: Wireless Configuration — with Optional Pager Transmitter
Wired Configuration
In a wired configuration (Figure 2), all pulse oximeters are connected to a
Communication Server (generally, the pulse oximeters are connected to a port in
the wall, which connects to the Communication Server housed in a data
communications closet). The Communications Server is connected to a Router/
Switch, which is connected to the Central Station (application server), where the
patient’s data may be monitored. The Central Station can be connected to an
optional Pager Transmitter: if pagers are assigned to a patient, alarms are
transmitted from the oximeter to the Central Station, then through the Pager
Transmitter to the assigned pagers.
In either configuration, the Central Station (application server) is the computer
running the Oxinet III software. The software displays all monitored rooms,
relevant Pulse Oximeter data, and alarms.

Alarms
Alarms are indicated both audibly and visually at the Central Station. If the
optional paging system is used, an alarm text message is transmitted to a pager,
displaying the room number, patient name, alarm message, SpO
2
value, and pulse
rate at the time of the alarm.
Note: The Oxinet III software performs database maintenance automatically: the
software temporarily closes the program, performs database file maintenance, and
relaunches the program at 10:05 am every day. This maintenance procedure
normally takes less than 45 seconds to run. During the brief period that database
maintenance is in progress, the system does not process any incoming data —
including alarms.
Reports
The Oxinet III software allows up to 72 hours of monitored data to be stored,
trended, and retrieved in a variety of printable reports. Reports can be run at any
time or periodic snapshots of oximetry data can be scheduled at intervals selected
by the clinician.
Pagers
Use of pagers with the Oxinet III system is optional, since patients are being
continuously monitored at the Central Station. If you decide to assign pagers to a
patient, you should assign both a primary and a different secondary pager. The
primary pager receives the alarm page within 10 seconds of the alarm. If no one
responds to the alarm by either silencing the alarm at the oximeter or resolving the
reason for the alarm, the system sends a notification to the secondary pager within
30 to 120 seconds of the primary page, depending on the settings for your
Oxinet III system. The range of operation from pager transmitter to pager is
150 feet with no intervening structures.
WARNING: It is essential that the Central Station be visually and/or audibly
monitored at all times to assure prompt response to alarms. Do not rely on
the pagers as the sole source of Oxinet III alarms. The Oxinet III system is a
secondary alarm notification system. It is intended to supplement and not to
replace any part of the hospital's device monitoring procedures (including
procedures regarding bedside pulse oximeters and responding to bedside
oximeter alarms).

Component Descriptions
Table 1: Wireless Configuration
Component Description
Pulse Oximeter The pulse oximeter monitors and processes patient data and
sends this digital data to the transmitter via the oximeter’s serial
data port. The following Nellcor oximeters are supported: N-395,
N-550, N-595, N-560, and N-600.
Transmitter The transmitter converts serial data from the oximeter to Ethernet
data and then transmits the data to the access point.
Access Point The access point receives the wireless data from the transmitter
and forwards it to the router/switch. A number of access points
can be installed together to create a Wireless Local Area
Network (WLAN), which can cover a single care unit, a single
floor, or multiple floors. The number of access points required to
create the WLAN is determined by the size of the area to be
monitored. Because every building is unique, access point
placement must be determined by trained personnel before the
Oxinet III installation. It is not recommended that an access point
be moved after installation, since the wireless coverage area will
be affected.
Router/Switch The router/switch receives patient data from the access point via
the Ethernet network connection (or through the Cat5 Patch
cable) then forwards the data to the Central Station (application
server).
Central Station
(application server) The Central Station (application server), which includes the computer that runs the Oxinet III software, displays all monitored
rooms/beds, relevant pulse oximeter data, and alarms. Oximetry
data is received from the connected router/switch and, if the
optional paging feature is used, sends the alarm data to the
pager transmitter for transmission to the assigned pagers.
Pager Transmitter
(optional) The pager transmitter receives the alarm data through the serial RS-232 port of the Central Station and sends a text message to
the assigned pager(s) that includes: the room number, patient
name, alarm message, time and date.

Component Description
Pusle Oximeter The pulse oximeter monitors and processes patient data and
sends this digital data to the Communication Server via hardwire
connection to the oximeter’s serial data port. The following
Nellcor oximeters are supported: N-395, N-550, N-595, N-560,
and N-600.
Communication
Server The communication server is hard-wired to each bedside location and converts digital serial data from the serial port of the pulse
oximeter to Ethernet data, then forwards that Ethernet data to the
Ethernet router/switch.
Router/Switch The router/switch receives patient data from the communication
server via the Ethernet network (or through the Cat5 Patch cable)
and then forwards the data to the Central Station (application
server).

Installation
Power and Space Requirements
Caution: Oxinet III system power cords should only be connected to
properly grounded 120V AC, 60 Hz outlets.
When installing the components, leave space beyond the dimensions listed in
Table 3 to accommodate cables and to provide adequate ventilation to prevent
overheating.
Place the optional pager transmitter in a location where it is not close to large
metal objects such as tall metal filing cabinets or metal desks, which tend to
interfere with radio frequency signals. In addition, the pager transmitter should be
placed at least 3 feet away from other electronic equipment such as computers,
radios, or PA systems to minimize interference with those systems.
Note: Typical symptoms of interference include flickering screens on the Central
Station or a computer monitor, or hissing/popping sounds coming from speakers.
If either of these symptoms occur, increase the distance between the pager
transmitter and the device experiencing the symptoms.
