The Sleep Medicine is a subspecialty of Otolaryngology that studies the functions of sleep, its disorders, and the impact of these disorders on the lives of individuals. The development of this medical science has been intense, attracting the interest of several other medical specialties.

Within it, one of the biggest growth areas refers to the Syndrome of Obstructive Sleep Apnea that, in the last 20 years has been introducing new concepts, innovations in procedures and treatments, with better prospects for patients.

Obstructive Sleep Apnoea Syndrome (Osas) is characterised by recurrent episodes of partial (hyponeia) or total (apnoea) airway obstruction during sleep, despite sustained breathing effort, usually resulting in frequent nocturnal awakenings, resulting in excessive sleepiness.

Your main symptom is snoring, but symptoms such as excessive daytime sleepiness (EDS), unrefreshing sleep, fatigue or insomnia; waking with respiratory pauses, gagging, or choking are also common. Thousands of people suffer from undiagnosed sleep apnoea. When this disease is not treated, it may increase:

  • the risk of hypertension, cardiovascular disease, heart attack and heart attack;
  • the risk of motor and occupational accidents;
  • the risk of male sexual impotence;
  • diurnal fatigue and cognitive impairment.

Sleep apnoea can be well conducted through several strong treatments. Some of the most common therapeutic approaches are the CPAP, oral apparatus, such as the mandibular advancement apparatus, laser Uvulopalatoplasty, radio frequency ablation and ORL surgery. The key to the most appropriate treatment begins with a good diagnosis.

Diagnosis of Sleep Apnoea

The severity classification of Osas is based on clinical and polysomnographic criteria. These diagnostic criteria are based on clinical signs and symptoms and on the objective findings of polysonography (PSG) or home monitoring examinations.

For the diagnosis of sleep apnea is necessary that the sleep study covers parameters such as: number of apneas and hypopneas, number of awakenings, percentage of stages of sleep, average heart rate and the occurrence of cardiac arrhythmias.

Nowadays, it is already possible to carry out the study of sleep at home, through several alternatives to the study carried out in laboratory, known as Polysonography (PSG). In this way, more people can be properly diagnosed and treated.

There are several options in the market for the study of home sleep. However, we use Watch-PAT technology, which provides more clinical data than any other equipment for this purpose. Furthermore, the device does not require sensors or electrodes in the body, being more comfortable and practical for the patient.

Technology for Sleep Medicine

Peripheral Arterial tonometry (Pat) is a new method proposed for the diagnosis of Osas. This technology uses a sensor that, through the venous pulse, continuously measures changes in arterial volume in the finger, which reflect sympathetic activity due to Awakenings.

Sleep apnea can be diagnosed without the need for nasal cannula or straining, because the device, placed in the patient’s fist and with a finger biosensor, measures real sleep time and sleep stages without the use of EEG electrodes in the head.

The patient uses Watch-PAT during the night and the next day returns it to download data recorded on the computer through software that will generate sleep study report.

The technology was validated compared to the PSG, authorised by ANVISA and meets the standards of AASM (American Association of Sleep Medicine). The American Academy of Sleep Medicine is an American Professional Society for the medical subspeciality of Sleep Medicine, which includes disorders of circadian rhythms. It was created in 1975. The organization’s functions include the accreditation of sleep medicine facilities in the United States.

It was also voted by Clevelande Clinic as one of the Top Inovattion of 2010.
