Hi all Low SPO2 saga continues, see previous posts for details, reason behind it still unclear. Any ideas will be appreciated! I'm CPAP user since 2017, with supplemental O2 since June 2023, pressure min 9.4 max 17. AHI still a bit high, 6 month average 7.6. Nighttime SPO2 with CPAP and supplemental...

What were the numbers?

Apologies for late reply.
Not sure about numbers, doctor just told ABG was normal.
Have an appointment in 2 weeks, can ask about numbers.
It would be good though to understand how low haemoglobin and low daytime SPO2 is linked to ABG

It's pCO2

ABG done in August didn't detect any abnormalities

By the way where you? From your accent you sound like you're from in or around Dublin.

What respiratory consultant? GP reckons respiratory consultant (apnea doctor) is in better position to investigate low SPO2, even though it's daytime SPO2. Looks like good old kicking can down the road complete PFT what does PFT mean? low O2 would make your hemoglobin increase, not decrease I know,...

We had a chat with GP about bloods and low O2 - her view is that haemoglobin is not bad for my age (60yo) and O2 is for respiratory consultant

Hi all Just a quick update and question: I'm using APAP with supplemental O2 every night for 6-7 hrs since June, pressure min 9.4 max 13. AHI is still high, between 5 and 10. Sleep disrupted, awakenings every couple of hours or so, almost no sleep after 4am. CPAP data shows mainly Unclassified/Centr...

another company who is cheaper and makes machines that use Imogen parts

Thanks for advice! Had a look at this concentrator, it's good, but delivers pulse flow, my understanding for use with CPAP flow should be continuous. Is this correct?

Hello 2 weeks ago started to use supplemental oxygen at night, 2 liters as prescribed. Oxygen concentrator (AirSep, model VisionAire 5) tube connects to CPAP tubing. SPO2 improves to 97-98 percent with mask on, but drops back to my usual 91-92 percent when mask removed. Sleep and daytime energy a bi...

The concentrator doesn’t need to be in your bedroom.
You can get long tubing and place it in another room

Thanks for your advice. Unfortunately for my place it's a bit impractical. It seems getting used to noise is the way to go.

Thanks Miss Emerita! Doctor's approach is one step at a time - try nighttime oxygen first, see how it goes, and then look at other options like daytime O2

Hello Quick update on my appointment with respiratory consultant in April and some questions: - supplemental oxygen prescribed for use with CPAP machine, contacted supplier to arrange this - sleep study and arterial gases tests planned for late June - new type of machine (Bilevel or ASV) might be ne...

Were you at all asleep between 04:45 and 06:00? Not really, after 4am usually it's drowsing, not real sleep How do you know your SPO2 is low during the day? GP measures SPO2 from time to time, but doesn't act on it. Also I own Contec finger oxymeter so do it myself. Any views if ASV machine would b...

Let us know how it feels.

Tightened my mask, put ice cubes in humidifier - inhaling and exhaling manageable, main discomfort is warm and humid feeling of exhaled air which it seems I'm inhaling again. Leaks reduced - see imgur below.

Find a doctor who will prescribe a 24 Holter test for your heart, and give you any further tests necessary. I know people who have had a 24 hour BP tracking, people who have had heart echo tests, etc. I had all above tests plus cardiac MRI and angiogram. Low daytime SPO2 seems to be caused by somet...
