Home Sleep Study in Campinas: The Sleep Apnea Exam Done at Home

If you are looking for where to have a home sleep study done in Campinas, Dr. Paulo Moreira performs the sleep exam in your own home. The type 3 study evaluates sleep apnea and, over a single night, records the signals needed to investigate snoring and pauses in breathing — without you having to sleep in a lab.

In practice, a portable device and a few sensors do the recording: a fingertip oximeter (blood oxygen and heart rate), a nasal cannula that measures airflow, a chest band that measures breathing effort, and a body-position sensor. You sleep in your own bed as usual and return the device the next day for analysis.

There are two home types. Type 3 is focused on breathing and is the one most used to investigate apnea. Type 2 is the full version: it includes the electroencephalogram and can stage sleep, indicated when the clinical question calls for a broader study. The choice between them starts with your doctor's suspicion.

The exam is usually indicated when there is loud, frequent snoring, breathing pauses noticed by a bed partner, unrefreshing sleep, daytime sleepiness, waking up short of breath, or a morning headache. It also has a role in the work-up of hard-to-control high blood pressure. It does not replace the consultation: it is a complementary exam, always interpreted alongside the clinical assessment.

Doing the exam at home has a real advantage: sleeping in your own bed tends to reflect your usual night better, with more comfort and no time spent adapting to an unfamiliar environment. In some situations — suspicion of other sleep disorders, or a need to stage sleep — the full study (type 2) or an in-lab exam may be preferable.

Preparation is simple. Keep your usual sleep routine, avoid naps, caffeine, and alcohol on the day of the exam, and come with clean skin (no creams) so the sensors adhere well. You will receive instructions on how to position the device before sleeping.

A medical referral is required for the sleep study, and the exam can be done privately or through a health insurance plan. If you are not sure whether you need it, it is worth talking first: describe your symptoms and Dr. Paulo will guide the next step.
