A good home sleep study uses a variety of equipment to monitor the patient's breathing throughout the night. One of the main benefits of a home sleep study is that the patient gets to do the study in familiar surroundings, which reduces first-night effect, notes CleveMed.
Home sleep study tests monitor the breathing of the patient, as well as the blood oxygen level, states Sleep Education. In some cases, the patient's heart rate is also monitored. While home sleep studies are suitable for some people, those with other medical conditions such as congestive heart failure or pulmonary disease should only have a sleep study done at a sleep study center. A sleep study is the only way to diagnose sleep apnea, notes American Sleep Apnea Association.
