Precise Meaning of MIN and MED
Precise Meaning of MIN and MED
Hi_ iahev been assuming that MIN is the lowest my SPO2 went and MED the average. My figures are usually around 89 for MIN and 95 for MED. I have looked for the meanings in the help sections but couldn't find the definitions. It is many years since I did Maths!
Have I assumed correctly? I should add that my nightly AHI is usually well ender 1, sometimes 0!
kindest regards

Re: Precise Meaning of MIN and MED
MED is short for Median:
To find the median: Arrange the data points from smallest to largest. If the number of data points is odd, the median is the middle data point in the list. If the number of data points is even, the median is the average of the two middle data points in the list.

Re: Precise Meaning of MIN and MED
Thank you kindly. I didn't make myself clear. All I see is MIN with a figure under it and then MED with a different figure. I have been assuming that these are the most important figures to take note of. So when it says 87 under MIN 87 is the owest my SPO2 went and 95 under MED is the average?
I didn't understand your reply at all. I don't recall any of my math excet the usual.

Re: Precise Meaning of MIN and MED
There is something important about the MED related to CPAP therapy, isn't there? I just can't remember what it is.
EDIT: This was actually a serious question that I actually wanted to know the answer to.

Re: Precise Meaning of MIN and MED
Why the snark? Just answer the question. Med is short for Median. Half of the values will be below the median and half above. It is a much better measure of central tendency than average. Extreme values can inflate or reduce the average. Median is not affected by extreme values.

Re: Precise Meaning of MIN and MED
Choosing the appropriate measure depends on the context and the nature of the data. If outliers are present, the median may be a better representation of central tendency. However, both measures provide valuable insights depending on the situation.

Re: Precise Meaning of MIN and MED
Definitely agree! What's happening on the fringe can be very diagnostic. Examples 95% measure of blood oxygen or leak rate. If I only looked at the median, it would suggest I never have any leaks but the 95% leak measure usually shows a value.
