Hi, galinha
I'm not a doctor, or sleep professional in any way. I'm a gradually self educated fellow cpap user - here's what I understand from those tables:

The tables in picture no.1 describe how the data was measured.

The other two picuture are the results.

Your sleep is badly disrupted (disturbed) by the many times you stop breathing.
RD - stands for Respiratory Distress (or Respiratory Disturbance)

OA - obstructive apnea is when you stop breathing because your airways close up and obstruct your breathing. You've got many of those - about 60 on the average every hour -meaning that not even a minute goes by before you're choking again.

CA - central apneas is when you stop breathing without obstructions. Your brain just doesn't give an instruction to breathe. This can happen for many reasons - for instance when you toss and turn in bed. You've got about 6 of those every hour.

MA - Mixed apnea are a combination of central apneas and obstructive apnes. You've got about 6 of those every hour.

OH - Obtsructive Hypo(a)pneas are times when your breathing is not entirely obstructed, by it is pratially obstructed. You've got 7.4 of those every hour.

Total AHI is the apnea+hypopnea index (no. of time per hour of all kinds of apneas + hypopneas)

The results of all those breathing disturbances are:
1. You never fall deeply asleep - you spend most of you time in stage 1 sleep - which is dozing - and stage 2 - light sleep. You are not getting the rest you need. Real rest occurs in stages 3, 4 and REM (Rapid Eye Movement) sleep - which is the dreaming part of normal sleep. The time you spend in variuos stages of sleep is your "sleep architecture". Your sleep architecture is disrupted by you breathing disturbances.

2. You also don't get enough oxygen (o2) into your blood. The oxygen saturation (SaO2) - average 76% is much lower than it should be in a healthy person. Not surprising considering that you are choking most of the time when you're trying to sleep. Not enough oxygen in your blood means not enough oxygen in any part or you body - since the blood is what brings the oxygen to where the body need it.

You did fall into light sleep quickly (this is the latencey), and you were(lightly) asleep for most of the time you spent in bed. And, according to these results, you only slept on your back.

These are all pre titration results. Titration is when they attempt to find out at which pressure you do best.

Since you already use an autopap you either already have titration results or else your doctor wisely decided not to wait any longer, and start you off immediately with a machine that will attempt to find out the pressure you need.

Based on the numbers on your tables, you have severe sleep apnea.
And you should make every possible effort to use the machine each and every time you go to sleep - and that means naps as well. Each and every time, no ifs and buts.

The good news is that if you make sure to use the cpap each and every time you sleep, you have a very big chance of getting over the problems caused by your Obstructive Sleep Apnea.

You can find a very informative video about sleep apnea - what happens etc. - in the following site Understanding sleep disordered breathing (It takes time to load)

Hope this helps. Good luck!

Based on this wich tritacion do you recomend ?

The report doesn't say what your titration should be. A doctor should have told you when he prescribed your machine.

However, your machine has software that should show you the average pressure. In a previous post, you said your pressure was 8.

Find it....my tritration is 7,24

What shoul i use ? In APAP ?

Thnks a LOT

Galinha, it is probably NOT possible for someone to guess at the pressure that will relieve someone.
If you apply constant air pressure to the nose or mouth of a person with apnea, the following will usually happen. At very low pressures there will be little improvement. As the pressure is turned up (by a technician performing the study while you sleep) there will be fewer apneas. This trend will continue until there is some maximum amount of relief. Further increase in air pressure will give no more relief, but will cause other negative effects to the patient.
During a titration study a technician gradually increases your pressure while you sleep and he monitors the results. This will show him, and your doctor, and you, at what pressure you get maximum relief. Your machine is then set either to deliver exactly that pressure if it is a CPAP model, or set to cover a small range above and below that pressure if it is an APAP model.
Does this answer your question?

Thnks

My tritation is 7,27

What range should i use in cpap ?

Luis,

Usually it's advised to set your minimim at 2 below your titration. And set your maximum at 2 or 3 above your titration number.

Galinha,

Much the same as ozlj, I'm also not a sleep professional, a doctor, or otherwise an expert. However, I recently went through interpreting some of these numbers with my own sleep disorder specialist, and thought I would share one observation with you.

I noticed (from ozlj's post - your links don't appear to work at this time), that your CA and MA numbers are identical. This was the case with me, also.

I asked my doctor if I suffered central apnea as well as obstructive apnea (as a condition, and not just an event). What she told me was that in cases like this, the central apnea is often a reaction to an obstructive apnea. Consider the following series of events:

1) You enter obstructive apnea
2) Your blood O2 saturation decreases
3) Your brain reacts by arousing or awakening you
4) Sometimes, you will unconsciously HYPERventilate during this time
5) Your CO2 blood levels increase
5) Your brain detects that CO2 levels are high, and HYPOventilates you (defers breathing) to allow your CO2 levels to return to normal

Obviously, I can't tell you that this IS what happens to you, but I found the explanation intriguing, and thought that others might be interested in the interpretation.
