The results of my smart card reading that the doctor showed me:

First page is headed Multiple Download Compliance Report:


It shows my name and my patient ID----Information for referring physician, PCP, clinician are all blank.

Then shows graphs on hours of usage between 8/28 and 10/12, shows me doing around 6 hours per night which is correct.says average humidifier setting at 1.0 but I never use the humidifier, last setting passive..........Average flex setting 1 (i'm set for 3), last setting 7 (what?).

Next on page is a graph showing 90% of EPAP and IPAP.

Next two pages show daily Patterns of use, each date is shown on left side of display but weekends are noted only as Saturday and Sunday (I wonder why)................This breakdown seems to show I use machine more on weekends but that isn't true......

The two page breakdown shows a graph next to each date, the graph shows darker colored indentations at points of the grey colored graph and some graphs show breaks (empty white spaces breaking up the daily graph) (some graphs have no indentations, those graphs are solid) and next to each graph is an hourly breakdown such as say 6:11/6:22 or 6:32/7:13. The solid graphs also show the empty white space breaking up the daily graph.

the bottom of the monthly graphs show a 12 14 16 18 20 22 0 2 4 6 8 10 and I'm sure that these are the hours when I use the machine, I'm an evening worker and I sleep from around 3AM or later.

Final page shows

Date Range
Days with device usage
Days without device usage
cumulative usage
maximum usage (1 day)
average usage (all days)
average usage(days usage)
minimum usage (1 day)
Percent of days with usage less than and percent of usage more than 4 hours.


What do the graphs show? What do the times mean? What should a Smart card reading show?
