Challenge: Calculate the percent from a typical CPAP humidifier assuming a person breathes in 3500 liters of air overnight. It's probably a low percentage. You can't and don't calculate relative humidities from a Cpap humidifier... You measure the relative humidity in the airflows. Try using a hygro...

I don't have to guess because I already know. It does not matter how many litters of air you breathe every night. On average a Cpap ( Resmed or Respironics ) delivers about 65 to 75% relative humidity. Add the heated tubing and it will decrease the humidity to between 60-70%. These are facts! I have...

Yes, go ahead and keep your bubble humidifier hooked up. People don't realize that an oxygen concentrator without humidity only puts out about 3% humidity! So if you don't use your bubble humidifier and you are bleeding in your oxygen you will be actually decreasing your total humidity from the Cpap.
