Need info on interpeting data from the ResMed S9
Unsure I've been using the S9 for a month now. I can extract the data using the SD card and read it on my PC. It would be helpful if there was some detailed information to explain what I'm looking at!
I'm a bit worried about the leak index in particular as it seems to be all over the place and I would think it would affect the other readings!
Does anyone no were I can get more information on interpeting these numbers (I looked at the documentation that came with the software but it doesn't say what the data really means, just what it is!

RE: Need info on interpeting data from the ResMed S9
Well, one place to start is here:
http://www.apneaboard.com/wiki/index.php?title=Wiki_Home
You can look up the terms and go from there.

Another is here:
http://www.apneaboard.com/wiki/index.php?title=Acronyms
That will help with all the "alphabet soup".

Here's another glossary:
http://sourceforge.net/apps/mediawiki/sl...e=Glossary

In terms of leaks, you want it to stay below that red line, since you are using ResScan. Any recording of an event during a time the leak is over that line (24mL) is not valid. If your leaks predominantly go over the line, then your priority is to get that fixed. Until then, the data is mostly worthless. You can use it as a reference but it will be skewed.

Thanks Paula that gave me some of the more important info I was looking for (i.e. keep leak time below the red line).

This might be of some help, it's the ResScan Interpretation Guide:

RE: Need info on interpeting data from the ResMed S9
see "ResScan guide for glossary (page 78) and graph interpretation
http://www.apneaboard.com/ResScan_Interpretation-Guide.pdf

Glossary
Apnea
The temporary absence or cessation of breathing.
An apnea is scored when there is reduction in breathing by 75% of the baseline breathing for at least 10 seconds.

ResScan shows three types of apneas:
Central Apnea
An apnea during which the upper airway remains open.
Obstructive Apnea
An apnea during which there is a physical closing of the upper airway.
Unknown Apnea
An apnea during which a leak higher than 30 L/min occurs, precluding accurate determination of whether the apnea is obstructive or central.

Apnea Indices
For all indices, the value shown for Statistics is the total number of events divided by the Daily Usage.

AHI (Apnea–Hypopnea Index)
The total number of events is calculated by adding the number of apneas and hypopneas events.
For the AHI graph, the AHI count is incremented whenever an event occurs and reset every hour

AI: Apnea Index
HI: Hypopnea Index
CAI: Central Apnea Index
OAI: Obstructive Apnea Index
UAI: Unknown Apnea Index

Average
A calculated value of a set of numbers computed by adding the total number of values and dividing by the number of values. Average for usage (therapy) hours is calculated over total calendar days.

Daily Usage
Daily Usage is the total usage in a single session (a session starts at midday and finishes 24 hours later).

Average Daily Usage
Average daily usage is the result of the sum of Daily Usage divided by Used Days, over a selected time period.

Median
The middle number in a sorted list of numbers. Half the numbers in the list are less, and half the numbers are greater (Example: 3, 3, 4, 5, 5, 5, 6, 9, 12, 23, 48: median = 5). Median for usage (therapy) hours is calculated over days used.

Median Daily Usage
The middle value for daily usage, where values for Daily Usage are listed from low to high, over a selected time period. While a few exceptionally
high or low values can have a significant influence on an average measure, the median is typically more reflective of the true central tendency.

Event
The occurrence of an apnea or a hypopnea. Events are recorded as they occur. The maximum number of events stored per session is 500. After 500th event, 501 replaces 500, 502 replaces 501, etc.

Flow
An estimate of the patient’s airflow during inspiration and expiration. It is derived by taking the total flow and removing the leak and mask vent flow components.

Flow Limitation
A measure of partial upper airway obstruction. This measure is based on the shape of the inspiratory flow–time curve.
A flattening of the inspiratory flow–time curve suggests upper airway obstruction.
A normal inspiratory curve would be round shaped
