Home Sleep Testing
Home sleep testing is now available as an alternative to a sleep laboratory visit. Portable monitoring equipment is used to assess your sleep in the comfort of your own bed. Whereas sleep laboratory studies using a minimum of 7 channels are classified as a Level 1 study, home studies are classified as Level 2, 3 and 4 depending on the number of channels recorded.
A Level 2 home study records a minimum of 7 channels of data and measures actual sleep time, which is the same as a full sleep study conducted in a laboratory without a sleep technologist being needed for this home study.
Most home studies are Level 3 HSAT (Home Sleep Apnea Studies), which usually record 4 to 7 channels and do not measure sleep. A Level 4 home study records only 1 or 2 channels that typically includes oximetry. Algorithms are used to guesstimate the amount of sleep for studies that do not actually measure sleep, and to calculate the number of apneic events per hour of sleep that is required for diagnosis of the sleep apnea syndrome. Home sleep testing is not recommended if you have serious conditions such as Chronic Obstructive Pulmonary Disease (COPD) or Congestive Heart Failure (CHF). If a sleep study is advisable yet significant health problems prevent you from meeting the standards for portable monitoring, then follow-up with your personal physician advising testing in a local sleep laboratory may be recommended.
BresoDx Home Sleep Test
Medical research and development by Toronto’s University Health Network and MARS Innovation created BresoDX®, a home sleep test that transforms the precision of a sleep laboratory into an accessible solution for the investigation of obstructive sleep apnea in adults. The technology was developed by Dr. Geoff Fernie, Dr. Doug Bradley and Dr. Hisham Alshaer. Bios of co-founders and co-inventors.
BresoDX®, worn over the nose and mouth using no cables or wires, captures breathing sounds and head movements for up to eight hours of sleep. A report is then generated and the results are interpreted by a sleep physician. BresoDX® has been validated in several clinical trials and provides a reliable scoring algorithm for consistent data analysis with a 95% agreement of the AHI index used to diagnose sleep apnea compared to the PSG sleep laboratory standard. BresoDX is licensed by Health Canada and has received the CE Mark indicating its conformity with health, safety and environmental protection standards for products sold within the European Economic area. It is also approved for sale in Turkey. For more information on this sleep test, visit https://bresotec.com/what-is-bresodx/
