A Trend Reporting and
Analysis System for
Pulse Oximeters
Download 2001 Chart Display
Overview

Download 2001 is a software package which
runs on Windows (95/ 98/ 2000/ NT/ XP)

Interfaces computers to a number of
different oximeters

This presentation describes the main
features & applications and is intended for
the respiratory or sleep technician/ clinician
Features & Benefits

Many oximeters store data internally and this
trend data is accessible to computers

Download 2001 allows you to move this
recorded data from the oximeters to your
computer to View and Analyse it

This is extremely useful both clinically and
for research purposes
Dl2001 with Oximeter

The computer serial port (or USB port via a
serial port adapter +) is connected to the
oximeter output connector P1 + Contact SSI

The handheld oximeter is in its docking
station*, both turned on with the ASCII 2
output mode set
* RDS 1, 1B, 3 or 3B

The oximeter and computer are powered up
and the Dl2001 programme run on the
computer in Windows
Oximeter Link
A mouse click on
the oximeter icon on
the menu bar
creates the link with
the oximeter
Simple Method
If you choose:
- ‘Automatically
download largest
recording’ and
- ‘Auto print report
after downloading’
sit back and wait
for the report to be
printed!
* tick the boxes
Otherwise….
View the data - checking the quality as
it comes in to the computer

(1)
Otherwise….
(2)
Choose required
recording from oximeter
recordings

Assign the patient
name and details to it

The data screen
(‘chart’) will then open

First Data Screen

This screen shows 10 minutes of the recording
Two SpO2 low alarm violated vents are shown in red as well as the
actual alarm limit (90)

Downloading Data to Computer:
Preparing for Next Patient

Oximeters typically store 24 hours or even up
to 72 hours (several nights of data) of data

The software can handle this amount of data,
but it is quicker to clear the oximeters
memory after downloading to the computer

It is then ready for the next recording
Controls and Data Manipulation

View the full study by clicking on an icon, or
see a different time period on screen with the I
(interval) icon

Step (Page) through the data

Pan through the data page by page (adjust the
speed with View | Page | Pan Rate)

View numerical values by moving the cursor
on the trace
Full Study or Interval?

Right hand side numbers
shown at vertical cursor:
- SpO2 value of 77
- pulse rate value of 61
Amplitude Control
Here the axis is being reset
to 70 - 100% Saturation
RH
Mouse
Menu

Fit To Scale (the trace) or
change the Amplitude
with the mouse right hand
button menu | Amplitude
control

Move and change the
amplitude using the
cursors - singularly or
together
Interval Control (The Ruler)

The Ruler allows you to control and see the
time interval marked between the cursors in
context of the recording (ie 3am - 4 am)

Cursors can be moved singularly or in
tandem by mouse - good for ‘nudging’
forward to see end of an event

The ‘Interval Icon’ can also be used to
change the interval in fixed steps
Analyse the Recording

Choose Analyse |
Analysis Report

Use Marked regions for
exclusion/inclusion of
chosen intervals

The other options (Plot
SpO2 etc) give single
pages from the report

be best to have the
envelope
