Obstructive sleep apnea -- a condition that causes people to stop breathing temporarily many times a night during sleep -- can be diagnosed in two basic ways. One is to send them to a sleep laboratory where they can be monitored overnight or, if a sleep lab isn't available, give them a portable sleep monitor to take home.
The portable monitors have become more widely used in the last few years, according to the co-author of the guidelines, Dr. Jon-Erik Holty, a staff critical care pulmonologist and sleep physician with VA Palo Alto Health Care System. Insurance companies tend to prefer the low cost of the monitors rather than the higher expense of sleep labs with employees who monitor patients overnight.
"For the average person, they're just as accurate as an in-lab study," said Holty.
However, the guidelines' authors cautioned that patients with congestive heart failure, chronic lung disease and neurological disorders should be checked in a sleep laboratory and not use a portable monitor.
The physician association is offering new guidelines about the diagnosis of sleep apnea as part of a follow-up to previous recommendations from the Agency for Healthcare Research and Quality, Holty said.
It's estimated that about 9 percent of Americans have moderate to severe sleep apnea, according to Holty. The condition is more common in older people, he said.
People with the condition often have trouble staying in deep sleep because their throats close, blocking th
