NEW Exam for Polygraphic Recording of Sleep – Level III

OBSTRUCTIVE SLEEP APNOEA

SNORING IS THE FIRST SYMPTOM

Snoring, that is, an intermittent noise registered during breathing, when the person is sleeping. It is often very uncomfortable for those sharing the same sleeping space. But it is also one of the first symptoms of a chronic disease. Obstructive Sleep Apnoea (OSAS) is a disease related with respiratory arrests during sleeping, with some consequent changes over the years, reducing life quality and expectancy.


Most common symptoms 


DURING THE NIGHT:

DURING THE DAY:

Chronic snoring;

Excessive Daytime Sleepiness (EDS);

Observed apnoea;

Sleepiness while driving;

Night suffocation episodes;

Waking up with headaches;

Nightmares,night sweats and agitation;

Irritability and Apathy periods;

Insomnia,frequent awakenings;

Depression;

Gastroesophageal Reflux Disease (GERD);

Obesity and Chronic Fatigue;

Frequent night time urination (adults);

Nocturnal enuresis (children).

Difficulty in concentrating,memory loss and decrease in libido.


Consequences of Sleep Apnoea


Cardiovascular Risk:

When you experience sleep apnoea, there is a greater cardiac effort to maintain necessary oxygenation during the night. Blood pressure and heart rate increase, instead of reducing. Extending this situation leads to Hypertension (HT), arrhythmia or coronary disease, highly increasing chances of myocardial infarction and stroke.


Neuro-psychic changes:

Chronic lack of oxygenation during the night leads to a degradation of cognitive faculties with implications in attention, vigilance, memory and the ability to make decisions. Depression and irritability. Deterioration of family and social relationships.

Excessive daytime sleepiness (EDS) is caused by lack of restful sleep. It is one of the frequent causes of traffic accidents or poor professional performance.


Aggravating factors:

Aggravating factors are mostly obesity, but also alcohol consumption, smoking, sedentary lifestyle, chronic respiratory diseases, nasal obstruction, neurological diseases, or some drugs such as benzodiazepines or beta blockers.



How is it diagnosed?


A medical appointment is important to check general health condition related to this disease. Clinical observation is fundamental as well as the prescription of appropriate complementary exams for a correct diagnosis.


The main exam for diagnosing sleep related diseases is the POLYGRAPHIC RECORDING OF SLEEP – Level III. It consists of registering, during sleep, several parameters obtained via small sensors placed on the person which are later electronically evaluated by qualified technicians.


When the study is specifically directed to snoring and obstructive sleep apnoea, either in patients with chronic snoring, when respiratory arrests are registered during sleep, in cases of excessive daytime sleepiness or in obese patients, physicians may prescribe a simpler exam (cardio respiratory), which takes place in patients’ home (ambulatory).


This exam is also common for chronic heart disease patients, with fibrillation or cases of hypertension difficult to control with usual medication.


Sleep study (cardio respiratory) – Evaluated parameters:

• Body Position

• Oronasal flow

• Respiratory movements (chest and abdominal)

• Oximetry

• Heart Rate

• Snoring



Treatments


These will depend on results of previously prescribed exams, patient type and age. Usually they are proposed by the consulted physician, after considering the severity of the disease and the patient’s clinical situation. However, to confirm disease and its severity a Polygraphic Recording of Sleep – Level III is needed.


Joaquim Chaves Saúde Miraflores and Cascais Medical Clinics already have a technical team qualified to perform this exam as well as physicians of specialties such as Otolaryngology, Pneumology, Neurology, prepared to monitor and treat SNORING and Sleep Apnoea Syndrome.
