Central Sleep Apnea
Sleep apnea with SpO2 of 69%, supplemental oxygen?
Had already posted a question, meant to ask this as well.
I went for a polysomnograph (sleep study), and it showed I have obstructive sleep apnea as well as some central apneas. My doctor told me I stop breathing approximately 45 times an hour, and my pulse ox, at its lowest, was 69%.
Question A) Is this critically low O2 saturation?
Question B) Will CPAP or APAP keep my pulse ox up, or will I need supplemental oxygen as well at night?
Question C) Have you ever seen someone's pulse ox drop this low with sleep apnea?
Thanks so much, folks!
I'm unsure what you are asking me this for. I am asking a legitimate question. I have a very minimal understanding of this subject, and have no idea about the scenario you presented...
Hello, there.
A) That saturation is low and definitely calls for supplemental oxygen. It is not the lowest I have seen during sleep studies, though. I'm a respiratory therapist who worked in a sleep lab for a bit, and seeing someone with really long apneas and extremely low saturations always made me want to get out of my chair and do something about it!
B) CPAP or BiPAP will help with keeping your airway open and avoid having so many episodes. I am sure your physician has gone over with you about the differences between obstructive vs. central apneas. One is where your airway becomes obstructed and does not allow for airflow to occur (obstructive). The other is your brain not sending adequate signals to control your breathing (central).
Sometimes these devices do help with the oxygen saturation, as there are less episodes of no breathing, but that can also be deemed incorrect. Unfortunately, some patients require supplemental oxygen on top of their "machine" treatment.
C) I have seen saturations in the 40's... that is when it gets really nail-biting scary. This does not mean that your saturations are adequate, though.
Please follow your physician's instructions. Remember that they do not mind answering questions you may have.
Hope I helped, and disregard the previous poster.
