I use the Swift Nasal Pillows. Could someone please tell me what the leak rate should be.

sleepyguy1,
Here are the leak rates for the Mirage Swift original. I don't know if the Swift II numbers are the same or not.

Pressure Leak Rate
4 20
8 29
12 37
16 43
20 49

sleepguy1,
My table in the previous post may not be clear--format was lost in posting. The last two numbers on the right are leakage rates. The numbers to the left of the last two digits are pressure numbers(4, 8, 12, 16, 20).

Sleepyguy,

You should be able to go into the Clinicians menu and select the Swift as the mask you are using. If you do or have done so, then your machine will display as its Leak Rate whatever is over the designated exhaust leak rate for your machine. In other words, if your pressure is 8, the leak rate for the Swift is 29, so if your total average leak for the night is 40, it will show your leak rate as being 11, or actually .11, which would not be too bad.

I understand now. I have been having a leak rate of about 30 and thought that was bad, and then read a post when said with a swift that was good. I do have the machine set for swift, so my reading must be the leak rate over and above what it should be. I tape my mouth securely so I need to figure how to get that down.

First of all ... ResMed machines list leak rates in their LED read out in units of liters per second.

Second ... ResMed machines list leak rates in their LED read out as a residual leak (it subtracts a mask's intended or designed leak rate from the total leak rate).

So ideally, the leak rate listed on the ResMed LED should be zero or very close to zero ... assuming you have the correct mask setting w/in the clinician menu (unfortunately only ResMed masks can be selected).

The Respironics machines list total leak rate.

can you program in the type mask with a M series box ?
