Respiration rate awake vs sleeping

[SingleH]

Hi all,

Should there be any correlation between day time respiration rate and your respiration rate during the night, or are they largely independant?

For example if your respiration rate is 13-14 during the day when breathing unassisted and then when using your machine at night its 18-19 would this be considered problematic.

Ive seen the guidelines suggest normal is between 12 and 20 breaths per minute and the resmed titration guide goes upto 30. If I lower PS below about 6 respiration will start creeping up into the low 20's.

Respiration rate during sleep varies by age and is given in ranges, not a specific number. From the studies I’ve read sleep respiration rate ranges are between 12-28 for an adult depending on age.

Awake versus sleep breathing would be rather independent. When awake, you consciously control it to a point.

Wouldn't a PS of 6 plus on a VAuto be a bit high? If lowering PS is affecting respiration rates, it could be that this PS setting is affecting more than needed.

Note that this comment is based on no info from your therapy thread. So I don't know why your settings are what they are.

Thanks for links and confirming!

Hi SarcasticDave94,

Your question about the PS being a bit high is indeed one of the reasons why I am asking, as I have been trying to see if I can bring it down. The reason for it was to stabilise the breathing waveform and reduce flow limits. As the PS gets reduced the waveform tends to just collapse into a mess and respiration rate goes up as PS goes down. To actually get flow limits to a decent number and a good waveform it had to be on a PS of 8 but that caused constant centrals, so around 6 struck a balance of maintaining good figures and a half normal looking waveform.

What would a bit higher EPAP and lower PS do for your therapy?

A person like myself would do OK with sometimes higher PS but not always. I have both Central and Obstructive Apnea, then COPD.

Anyway, if you're trying to bring down FL, there's probably 2 ways to attack. That would be increased PS or EPAP. Since higher PS affected breathing in some way, maybe swapping the numbers may help.
