Before oxygen therapy is prescribed there are guidelines or criteria that must be met. These criteria involve a blood test. (These blood test criteria must also be met for Medicare and other insurers to pay for the oxygen costs.) Medical experts produced the criteria. They establish what the levels of oxygen in the blood must be for oxygen therapy to be needed.
You might be surprised at some of the things around the house that can cause trouble. For example, some air filters that help rid the air of dust give off small amounts of ozone, an air pollutant that is a lung irritant.
“Ozone can certainly be problematic for people with COPD,” says Byron Thomashow, MD, professor of medicine at Columbia University Medical Center in New York City and chairman of the COPD Foundation. “That’s why I usually recommend HEPA filters,” which don’t give off ozone.
Here are nine other household hazards for people with COPD:
1. Air Ducts Filled With Dust
The forced-air heating and cooling systems found in many homes can blow dust and other irritants throughout the house. Cleaning the air ducts periodically can help alleviate this problem.
2. Carpets That Collect Dust and Dirt
Rugs and carpets are another major source of dust and dirt. “Every time you walk on a carpet or rug, you stir up a cloud of dust that you may or may not be able to see,” says Neil Schachter, MD, professor of medicine and community medicine and medical director of the respiratory care department at Mount Sinai Medical Center in New York City.
Wall-to-wall carpets cause more trouble than rugs, because they tend to be bigger (and therefore harbor more irritants) and harder to clean than rugs (which can simply be rolled up and taken to a cleaner). New carpets can be especially irritating, because they can “out-gas” formaldehyde and other noxious organic compounds for an extended period of time after installation.
