Patient FAQs


What if I can’t do 90 minutes at a time?

While we highly recommend sitting for the full 90 minutes, if you experience discomfort sitting for this long or you need to use the bathroom, you can break up the treatment into two sessions on the same day. You should speak to your AOTI representative if you think you won’t be able to do the full 90 minutes at a time.

What if I miss a treatment?

Refer to your prescription for the minimum number of treatments you should do each week. If you miss multiple treatments in the same week, you can do two treatments in one day.

What if I want more frequent treatments?

If you are able to sit for more treatments per week, you may do so. You cannot overdose on oxygen therapy. However, we encourage you to maintain a good balance of your daily activities so that you don’t wear yourself out.

Can I reuse Boots?

Is it hard to set up and use?
