Haemoglobin saturation curve needs legend[edit]

The Haemoglobin saturation curve has 3 series: a dotted green series, a solid blue series, and a dotted red series. Can anyone provide a legend so the reader knows the difference between the 3 series? Or perhaps this can be explained in the caption below the chart.

moving the info[edit]

I'm moving the info from oxygen saturation over here, with basic info from here over there. Makes more sense that way, any objections let me know. Silenceisgod (talk) 22:46, 22 February 2011 (UTC)[reply]

Technical Error?[edit]

I think I see a technical error but don't know the correct number Look at the third line on the table and I bet "80%" should read "60%". The line reads as below.′ 80% and less Loss of consciousness on average — Preceding unsigned comment added by 47.144.149.166 (talk) 04:47, 30 September 2019 (UTC)[reply]

We need better references and a better explanation of why the oxygen level fluctuates during the day and what is normal[edit]

cf "The needs of the body's blood oxygen may fluctuate such as during exercise when more oxygen is required [3]" - this reference 3, refers to https://www.fitday.com/fitness-articles/fitness/cardio/understanding-blood-oxygen-levels-at-rest.html - stating just that - there's no reference to any scientific literature. E.g. you have your teenager running around with an oxygen meter during covid19 and see they come home and has a saturation of only 87 one day and 2 other days it's only 88. How to interpret that? Please help. Thy, SvenAERTS (talk) 20:23, 14 March 2021 (UTC)[reply]

Effect of altitude[edit]

"Normal arterial blood oxygen saturation levels in humans are 97–100 percent."

Should add that this is only "at sea level". See e.g. [1].

Notably, "normal" is implicitly defined as for healthy humans with no abnormal physiology. Humans living at high altitude can still be healthy and with no abnormal physiology.
