Question:
second sleep study?

I just had my 3 hr psych evaluation and am scheduled for another sleep study. I am already approved for surgery and have a date for May 5. Is this second sleep study still necessary. I was told i had severe sleep apnea which dr is now aware of    — bikermama (posted on April 8, 2008)

In the second sleep study they will see how putting you under will effect you and how long the doctor has to safely perform the surgery before you need to come out of it and wake up. If it is very bad sleep apnea, they might convert you to an open proceedure. This is much faster for the surgery, but harder to heal from. Best of success to you.

Do already have a CPAP machine to use at night? I had to go a second night so I could use the CPAP machine all night. The respiratory therapist will find the settings that are ideal for you with your home unit, and they also take measurements (oxygen levels, snoring, etc) while you are on the machine to compare with the pre-machine readings. It was after this second test I got my machine. BTW - as much as I didn't want the machine - I have to admit it's made a huge difference in getting restful sleep! Congratulations on your date!

I was in the same situation being already approved for surgery and then having to get a second sleep study. I am scheduled to get my CPAP machine this Friday and I was only diagnosed with a moderate case of sleep apnea. But as others have said I have to be on the CPAP machine being as though they may have to convert my surgery to open rny instead of lap rny. I will be on the machine for 6 weeks before my surgery and then will be reevaluated again afer surgery but I was told that it really helps you get a good nights rest. I hope this helps and good luck with your surgery.

I had 2 sleep studies and they dont put you under for anything. Usually this is when they have you wear a CPAP machine. You will sleep with it and they will test you during the night to see how well you did with the machine. I woke up and felt like a totally new person. But after you have the surgery and lose the weight you probably wont need the CPAP for long. Good luck.

I have worked in the Sleep Disorders field since 1995 and am an RPSGT and REEGT. Your second sleep study is most likely to titrate you on CPAP (Continuous Positive Airway Pressure.) Since you have already been diagnosed with severe Sleep Apnea, you need CPAP at night. CPAP acts a a splint to hold your upper airway open for you allowing you to breathe freely on your own during sleep, eliminating your apneas. You stop breathing at night repeatedly because your upper airway obstructs. Once you lose a lot of weight, the sleep apnea may go away, or significantly be reduced. Sleep Apnea is not always caused by obesity, there are slim people who have it. Various causes block the upper airway; some people just naturally have too narrow of an airway or an enlarged tongue, tonsils, adenoids, elongated uvula, and so on... Obesity further constricts the upper airway with fat. Now that your surgeon is aware of your sleep apnea, they can take the appropriate measures to ensure your airway remains patent during surgery, such as intubation, and choice anesthetics. Don't worry, you'll be fine and looking beautiful and healthy all too soon!! Best wishes!

Hi, my surgery date is May 8th and I am excited. The second sleep study is important. It will allow them to fit you for your c-pap machine which is a God send. I get a good night sleep now. Good luck and God bless.

I don't know why they want a 2nd night unless, as other folks said, they need to make sure the CPAP is getting your oxygen levels where they need to be and your airway remains open. On a positive note, I got my machines 2 nights ago and I think I'm going to love it. I was diagnosed with mild apnea and feel better today. So I am sure you are going to be so happy because you will feel so much better and so much more rested. It's all good! Good luck to you!
