Sleep Apnea Test in Sharjah

What is a sleep apnea test?

A sleep apnea test, usually called a sleep study, measures what happens to your breathing while you sleep. Small sensors track airflow at the nose, the movement of the chest and abdomen, the oxygen level in your blood through a clip on the finger, your pulse and your sleeping position. Together these show each pause in breathing (an apnoea), each shallow breath (a hypopnoea) and how far oxygen dips with each event.

The result is summarised as a single figure, the apnoea-hypopnoea index: the average number of pauses and shallow breaths per hour of sleep. That figure, read alongside the oxygen pattern and your symptoms, places sleep apnoea in a mild, moderate or severe band. At Dar Al Kamal Hospital, Sharjah, the pulmonologist in the Pulmonology service interprets the study, so the person reading the traces is also the doctor who plans your treatment.

Who needs it

A sleep study is worthwhile when the signs of disturbed breathing at night add up. Common reasons for referral include:

• A partner who hears loud snoring broken by silences, then a snort or gasp
• Waking unrefreshed after a full night, or dozing in meetings, at prayers or in traffic
• Morning headaches, a dry mouth on waking, or getting up at night to pass urine
• High blood pressure that stays high despite treatment
• Atrial fibrillation, heart failure or type 2 diabetes, where sleep apnoea is common
• Weight gain around the neck and waist
• A job that involves driving, operating machinery or long shifts

The first step is a short questionnaire about how likely you are to doze in everyday situations, together with neck size, weight, blood pressure and a look at the nose and throat. This tells the pulmonologist how strongly apnoea is suspected and which study suits you. When a narrow nose or throat, large tonsils or a bent septum look like the main cause, the ENT team reviews the airway through sleep apnea treatment. Insomnia, restless legs and other sleep problems are covered by the neurologist under sleep disorder treatment.

What happens

There are two main forms of study, and the pulmonologist chooses between them at your first visit.

Home sleep study. You are shown how to fit a compact recorder with a nasal sensor, chest and abdominal belts and a finger clip, then take it home and sleep in your own bed. You return the recorder the next day for the data to be downloaded. Home studies suit many adults with typical symptoms and a strong suspicion of apnoea.

Overnight study. A fuller recording, which can add brain-wave and leg-movement channels, is used when the picture is less clear, when lung or heart disease affects breathing, or when a home result and your symptoms point in different directions.

Once the study is read, you and the pulmonologist go through the result together. If CPAP is recommended, set-up follows: a small bedside unit delivers steady air pressure through a mask to keep the throat open. Mask type and fit are chosen with you, the machine is supplied through an arranged equipment provider, and pressure settings are guided by your study. Weight reduction, sleeping on your side and cutting evening alcohol and sedatives form part of every plan, with support through weight management and smoking cessation where helpful.

Preparing for it

On the day of a home study, keep to your usual routine so the recording reflects a normal night:

• Avoid caffeine from the afternoon onwards and skip daytime naps
• Leave out evening alcohol, which deepens airway collapse and distorts the result
• Take your regular medicines as usual and bring a full list, including anything used for sleep
• Remove nail varnish or acrylic nails from one finger so the oxygen clip reads accurately
• Shave or trim a thick moustache if the nasal sensor is likely to slip

If you smoke shisha, dokha or midwakh, or vape, mention it, since these irritate and swell the throat lining. Bring any previous sleep study reports and ask your partner to note the nights they hear pauses.

Afterwards

You can drive, work and carry on normally the day after a home study, and the result appointment follows once the data has been reviewed. If you start CPAP, the first weeks are an adjustment period. The machine stores nightly usage, mask leak and remaining events, and the pulmonologist reviews this data at follow-up to fine-tune pressure and mask choice.

Air conditioning dries the nose and throat, so a heated humidifier often makes CPAP more comfortable in the UAE. Plan ahead for Ramadan, when sleep is split around suhoor, and for travel, since the device goes in hand luggage.

If you feel drowsy at the wheel, stop somewhere safe and rest before continuing. Hold off on long drives until treatment is working and your sleepiness has improved.

Contact the hospital if daytime sleepiness returns, the mask causes sores or leaks, or your weight changes markedly. For chest pain, severe breathlessness or a very irregular heartbeat, call emergency services or go to the nearest emergency department.

Cost and insurance

Most UAE insurance plans cover the pulmonology consultation. Sleep studies and CPAP equipment frequently require pre-approval, and equipment cover varies widely between plans. Dar Al Kamal Hospital, Sharjah can help you confirm your cover before the study on 06 599 7777.
