there is pulse and continous flow. should not sleep with pulse for a few reasons . continous flow has a steady flow all the time

You are asking great questions. A setting of 4 on pulse isn't necessarily the same as 4 continuous. You need an oximeter to really be able to tell the difference. You can buy one cheap at Walmart or Walgreen; I prefer a medically calibrated one by Nonin available on Amazon and other places on the internet; just google it.

It's all O2, whether it's oxygen as you say, or pulse dose. Both deliver O2, it's just different. If you are getting 4LPM from an electric concentrator or a tank, that means that assuming your breathing is relatively normal, you'll get about 4Liters Per Minute just by breathing normally. All the time you're not inhaling, the O2 just goes into the air and isn't used. Pulse dose is designed to make tanks last longer, so they only deliver a "bolus" of O2 when you trigger it by inhaling. The rest of the time, there's no O2 flowing. Depending on the conserving device that's used, that bolus can vary and some conserving devices need to be bumped up a bit to give you what you need.

You know what you're comfortable with at 4 continuous. Use your oximeter to see what your O2 saturation levels are when you're on that. Then check when you're on 4 pulse to see what they are then. My guess is that they'll be significantly lower and you need to turn the pulse dose device up to get enough O2 to keep you comfortable and in a good O2 saturation range. You don't want to go lower than 88 and most of us find we're comfortable at the 90-95 range. When I was first introduced to pulse dose, the RT from the provider actually had me use it to be sure I could trigger the bolus and that I was comfortable with it.

Neither is bad; both can be great. I use pulse almost exclusively except at night when I sleep and much prefer it. You want to do Pursed Lip Breathing (PLB) as much of the time as you can. m practice that until it's second nature and that's the way you breathe when you're doing anything except sitting. It's especially important with pulse, because you want to be sure that you're getting the O2 into your system and that you're blowing off the CO2 when you exhale. With pulse, you should just breathe normally, and the pulse should give you the bolus as soon as you start your inhale.

If you have more questions, please ask, but I hope this is helpful.

pulse is a measured dose and you need to breath in through nose to receive it, when you sleep your breathing either through your mouth or shallow breathing through nose.that is where the problem lies. need continuous flow for sleeping. during the day pulse is OK

I have portable constrater it's a pules only breathes when you do through your nose I'm a mouth breather I find it harder to breathe when I'm away from my home I feel like I'm suffocate because I have to breath through my nose when I get like that I open my mouth I'm gasping for breath then I have to stop and try to calm down with pers breathig amy suggestion will be appreciated

If you use a POC, there are only four or five that actually will produce continuous flow and they are all 10 pounds plus, so not really good to carry. They do come with carts. The POCs you carry are all pulse. I use pulse dose most of the time, and I usually breathe through my mouth. It works just fine.
