* '''Dotted lines:''' Oscar will display dotted lines across a graph to aid in reading it. The available lines will vary depending on the particular graph. Right click on a graph title and select "Dotted lines". A pop-up will appear, with a list of available lines which you can turn on or off.

Positional Apnea is caused by misalignment of the airway typically tucking the chin down.<br />

Periodic Breathing can be confirmed easily on this chart and serious breathing patterns such as CSR can be identified and Flow Limits become readily apparent.

Note: ResMed (incorrectly) labels all periodic breathing as CSR.

All Periodic Breathing should be viewed in a zoomed view to identify its properties.

The pressure graph shows the pressure as it varies over time. The mask pressure graph shows the pressure at the mask on a breath by breath basis.

ResMed: Flow Limits are calculated as an index, 0-1, indicating the flatness of the breath-form on the flow rate chart. Zero means none, severity increasing as the index approaches one. These show as a varying height vertical bar.

The leak rate graph indicates whether excessive mask leaking occurred, and to what extent. All CPAP masks are designed to leak or vent surplus air away from the user's nose or mouth. This flushes away the exhaled breath and prevents the user re-breathing his expelled CO2. The actual amount of this designed leak will vary according to the mask. Anything in excess of that amount is "additional leak".

Resmed and Philips machines both show snoring as a graph with the height of the trace indicating the intensity of the snoring. In addition, Philips machines show individual snores as events labeled VS1 and VS2 (vibratory snore 1 and 2). It is usually suggested that VS2 be turned off when presenting screenshots for discussion as the large number of events recorded can overwhelm other data on the charts.
