I have found the cause of the spike in pressure a sudden change in breathing pattern.
Why ??
RE: Hypopnea response - G. Szabo - 06-08-2024
You probably changed your sleeping position. Or you were doing something as small as turning your head.
BTW, you have obstruction both before and after the "spike".
RE: Hypopnea response - Made - 06-09-2024
Is this flow limited breathing???
RE: Hypopnea response - G. Szabo - 06-09-2024
Inhalation flow limitation because the peak is plateaued.
RE: Hypopnea response - Made - 06-09-2024
I have always thought that my limitations have been caused by my nasal obstructions. WRONG
Those waveforms are from me using a Oracle for a few minutes this afternoon so they are not nasal limitations.
The big question is how can i fix it bearing in mind that I still get limitations at 20 cm pressure
Loose 10 stone !!!!!

The pressure on your posted example is about 9.

This is using my normal Vitera full face mask

You have a severe flow limitation. If you are using EPR=3, then nothing more can be achieved with this device. As SarcasticDave suggested earlier, you should switch to a more advanced instrument capable of higher pressure support.

But because my AHI is normally below 1 and my useage is good my hospital cant see any problem.
This is the NHS in the UK

It would be best if you recorded your oxygen saturation overnight. They will change their mind if it is below 90%.
