Since they were trying different pressures, you experienced everything from air-starvation at low pressure, to pressure higher than you can comfortably tolerate, all without any exhale pressure relief (EPR). When you eventually are dispensed your own machine there is a lot you can do to get more comfortable. The important part of a titration study is to not just find your "optimal pressure" but to rule out CPAP induced central apnea. The biggest problem with a titration study is the recommendation of a single pressure that is "best". Don't let that keep you from getting Auto CPAP.

Thanks for the explanation Smile It was an interesting experience.
I'm in the process of familiarising myself with the machines available in order to make a good choice, and depending on how a short rental period goes with them, will be able to be more informed before I buy.

Better late than never, but I finally figured out how to get the images from my initial sleep study email to here. I had to take photos and upload them from the screen so apologies for the weirdness.

This was a very revealing chart.  Note the flow line where obstructive apnea are noted with duration.  You can see the apnea ends with a couple inspiratory peaks that are ragged and downward sloping. Those are classic obstructive flow limitations, and they are present from beginning to end of the 5-minute epoch with a couple recovery breaths., You see 6 or so flow limited breaths, two recovery breaths, then flow limits, and finally apnea.  The suppressed SpO2 goes right along with the flow limits, and snores on each one. The big disturbance halfway through the chart is a full arousal and the recovery breaths associated wtih it rapidly increase SpO2 back to 97 (normal).  And people wonder why they don't sleep well.

Ok, wow. LOL I sleep well (as far as being unconscious goes Wink ).. I just don't wake well :p

Here's the bit that was cut off from the top of that chart - I found it all a bit confusing.. if sleep efficiency is normal, I don't get the rest of it LOL.

Overview of results
• Severe obstructive sleep apnoea (AHI 32/hr). Both sleep and REM latencies were markedly reduced. Sleep efficiency was normal and sleep was consolidated with arousal index at 19/hr. Respiratory events were associated with oxygen nadir of 86%. 3 minutes were spent with oxygen saturations <90%.
• Snoring in all sleep-positions.

My machine arrived this morning. Impressive shipping, I must say. Shipped from Las Vegas on Tuesday, arrived yesterday evening, but we missed it so the guy brought it in this morning.
Unboxing is most enjoyable LOL
Very much looking forward to getting this baby going.
I do have a quick question. Humidity is very high here (an 11 litre bucket of water is full from an overnight portable aircon unit), so would I need to even bother with the humidifier?

Even with high humidity, a passive humidification is nice. Just put water in the chamber and don't turn on heat. With Climateline, my summer settings are manual 3, 72-degrees F. That essentially does not add heat from the tubing and is a low humidity setting.

Welcome to the A10A 4H club! I started into the biz yesterday! Fire away with your questions: I probably have them too.
