→Session times chart
===Session times chart===
Gives a graphical representation of the time when the machine was turned on then off. If you sleep all night long the bar will be solid. If you have one or more breaks the bar will likewise have breaks in it.
A session times chart with multiple breaks in the bars indicates the patient is having disrupted sleep and is either not toleratin g CPAP treatment or else has other medical problems which are disrupting sleep.
===Pressure chart===
[[File:OSCAR Overview Pressure.png]]
The pressure chart indicates your maximum and minimum set pressures as well as the actual pressures (minimum, median, 95% and maximum actually experienced through the night. A more sophisticated machine such as a bilevel or ASV will have multiple colours, indicating different pressures for EPAP, IPAP and so forth. Again, resting the cursor over a bar will bring up a balloon with the relevant details.
===Total time in apnea chart===
As the name suggests, this is a simple measure of the total time spent in apneas during the night.
===Flow limitation chart===
Indicates flow limitations - a narrowing of the airways which does not qualify as an apnea or hypopnea. Resmed machines score flow limitations on a scale from zero to one..
==Leak rate and large leak charts===
The leak rate chart shows leaks in L/min. The chart uses shades or colour to differentiate minimum, median, 95% and peak leaks.
The large leak chart shows the percentage of time the leak rate was above the "red line" threshold.
===Tidal volume, Minute vent and Respiration Rate charts.
These charts all show the minimum, median, 95% and peak for each of the relevant parameters.
For a discussion of these parameters see [[]].
===Periodic breathing===
This chart shows the percentage of each night during which periodic breathing occurred. High numbers and/or an upward trend could indicate respiratory or heart problems and should be referred to your doctor. Low numbers and occasional incidences can usually be ignored.
