# Buttons (bars) to turn sessions on and off. Clicking on these buttons will include or exclude sessions from display of the night's data. Clicking on the blue and yellow session buttons will include or exclude sessions from the display of the night's data. This can be useful if (for example) you had a very brief nap in the afternoon and want to exclude it from the night's results. Note that turning a session off will change the calculated AHI for the night. Note also that sessions can be turned on and off using the small green/black buttons in the section information panel. When a session is off the button changes to black / red.

=== The Calendar ===

|You can see a pie chart depicting the breakdown of your events.

To turn the pie chart on and off, press '''Ctrl-P''' on your keyboard. Alternatively, use the menu item '''View | Show Pie Chart'''. For posting charts to the forum it's best to turn the pie chart '''off''' as it covers up more valuable information.

=== Tabs: Details, events, notes and bookmarks ===

** Oscar will calculate your '''body mass index (BMI)''' at the bottom of the Notes section. You must enter your weight each day. You must also enter your height in your profile (see [http://www.apneaboard.com/wiki/index.php?title=Running_OSCAR_for_the_first_time Running Oscar for the First Time] ). If either the weight or height are not entered the BMI calculation will not appear.

* The '''Bookmarks tab''' lets you record the time of significant events you may wish to refer back to, such as an exceptionally long apnea.

===Creating a bookmark===

Bookmarks are created using the [[http://www.apneaboard.com/wiki/index.php?title=OSCAR_Organization_-_Daily_Page#Tabs:_Details.2C_events.2C_notes_and_bookmarks bookmark tab]] on the daily page:

# Click on the tab to open bookmarks

# On the flow rate graph, place the cursor on the event you wish to record (eg an apnea)

# Click the Add Bookmark button. A bookmark stating the time and date will be created.

You can add text to a bookmark:

* '''Y Axis:''' If you want to change the vertical scale of a graph, right click in the label of a graph and select "Y axis". A small pop-up will show, and give the options Autofit, Defaults and Override. Select override, the adjust the minimum and maximum numbers until the trace on the graph is to your liking. Note that you must keep the mouse cursor within the pop-up - if it strays outside, the pop-up will disappear.

* '''CPAP overlays:''' Oscar can include a marker for each of the events on any of the graphs. Right click the graph title and select 'CPAP Overlays'. A pop-up will appear, allowing you to turn on or off each type of event. The events will appear as a short tick along the top of the graph.

===Event Flags===

The event flags graph normally appears at the top of the stack. It shows each event (apnea, hypopnea, large leak etc) as a vertical bar. You can select which events to display using the event flag selector at the bottom left of the chart area. The available flags will vary depending on your machine. The graphical display of events is useful in determining whether they occurred at a particular time, in clusters or spaced through the night.

Each event type in the event flags graph will have a corresponding entry in the side bar summary area.

===Flow Rate===

This graph is probably the most used in analysing and interpreting CPAP data. It shows airflow in and out of your lungs throughout the night. Flow above the zero line is inhalation and below the line is exhalation. The events are shown on this graph as well as on the event flags graph. You can zoom in to examine an event more closely.

Placing the cursor on any event will create a small pop-up detailing the type and duration of the event in seconds.

===Pressure and Mask Pressure===

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.

Zooming in shows how the mask pressure is a high resolution chart sampled 25 times per second, while the pressure is only sampled once per second. Depending on your machine settings there may be several traces shown - usually the pressure in inhale (IPAP) and on exhale (EPAP).

===Flow Limitation===

===Leak Rate===

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".

Philips machines show two traces - total leak and additional leak. It is the lower additional leak line which indicates whether the leak is excessive or not.

===Snore===

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 labelled VS1 and VS2 (vibratory snore 1 and 2). It is usually suggested that VS2 be turned off when presenting screen shots for discussion as the large number of events recorded can overwhelm other data on the charts.

=== Oximetry Data ===

If data has been imported from a Zeo sleep monitor device, additional graphs will be available, including Sleep stage,
