Ok, in order.
AHI is the Apnea Hypopnea index. It is the average number of apnea events per hour. A value of 5 or less is considered normal. Last night, you scored 0.27. Over the last 7 days, you averaged 0.51. Over the last 30 days, you averaged 0.56. Over the last 6 months, you averaged 0.52. Over the last year, you averaged 0.53. These are excellent numbers, and indicate that your apnea is well under control.
RERA is a Respiratory Effort Related Arousal index. It is the average number of RERA events per hour. A RERA event is where the machine detects a change in breathing that might signify that you are starting to wake up. Those values are also excellent. It looks like you are sleeping soundly.
Hours / Night is just what it sounds like: the number of hours every night that you use the device. It looks like you are regularly getting around 7.5 hours of sleep per night. That is a touch low, but if you're good with that, there's nothing wrong with it.
Pressure is your treatment pressure. It's much more interesting in an AutoCPAP machine. With your fixed-pressure CPAP device, it simply shows that you've been at 13 cmH2O for quite some time.
Avg Total Leaks is the average amount of total leakage in the airway system in liters per minute (L/min). This includes the intentional leak because of the vent in your mask. According to the
manual on your Swift FX nasal pillows, at a pressure of 13 cmH2O, the expected leak rate should be around 38.5 L/min. Your numbers are right around there, so on average, it appears that you have no leaks.
95% Total Leaks is the total leakage value that you are at or below 95% of the time. This is typically going to be higher than your average. Going by your expected leak rate, a 95% total leak rate of 62 L/min means that your 95% unintentional leak rate (total - intentional) is around 23.5 L/min. A leak rate of 24 L/min is considered the threshold for a "large leak", so 95% of the time your unintentional leak rates are acceptable for treatment. This is also a good number.
Finally, there is the prescription setting. It appears that you first started using CPAP on 1 August 2012, and since then have stayed at a fixed pressure setting of 13 cmH2O with a CFlex+ setting of 3.
If I were your doctor (and if I were a doctor), I would be very pleased with these numbers and tell you to keep up the good work.
