Today, according to the 2010 US Census, 260,073 people of Hmong descent reside in the United States up from 186,310 in 2000. The vast majority of the growth since 2000 was from natural increase, except for the admission of a final group of over 15,000 refugees in 2004 and 2005 from Wat Tham Krabok in Thailand.

Studies show that if you meet the criteria for continuous oxygen use, using it less than 18 hours a day is probably equivalent to using none at all. If your doctor prescribes 24-hour daily oxygen therapy you should try to use it as close to 24 hours a day as practical. Of course there are times you may need to take it off, when you shave or put on make-up or do other daily hygiene. This is not harmful for short periods of time.
