RE: Bipap Pressure Suggestions
Respiration is a fickle creature. We push on one aspect like tidal volume, then don't see a rise in minute vent because respiration rate drops. If you want to try higher PS to increase Vt then, I would suggest smaller increments than 1-cm and observing results to see what is accomplished. I would suggest a 0.4 cm increase to start. It sometimes helps to increase trigger sensitivity to give PS a head-start on inspiration. This also seems to reduce CA events. We really want to stay away from your aerophagia threshold as it can really spoil an otherwise good night.
RE: Bipap Pressure Suggestions
Thanks SL.
What is a good respiratory rate/tidal to have?
At what level should you worry and is it something you should actively work to improve?
I wonder if the reason i wake up with headaches is because of that.
RE: Bipap Pressure Suggestions
Normal tidal volume is a range and is dependent on your height, ideal weight, age and fitness levels. It's almost impossible to make a judgement based on the Oscar stats unless it is exceptionally low or high (200s or over 800s), or without really good knowledge of the individual and their health. I don't try, but your Vt is right down the middle for someone under 6-feet tall. Similarly, respiration rates vary a lot, but I like to see over 11 and under 20 as a general rule with minute vent falling in an appropriate range. All of that probably meant nothing, other than you probably fall into a normal range. You can't even rely on the respiration rate to be accurate because flow anomalies will cause these CPAP machines to improperly count respiration rate, and we have to manually count the breaths per minute the machine count.
