Apap Machine

Overview

An APAP machine (Automatic Positive Airway Pressure) is a small bedside device that gently blows air through a mask while you sleep. The steady airflow keeps your throat open so you can breathe normally. It is a type of CPAP (continuous positive airway pressure) machine, but with a clever difference: an APAP can sense how much pressure you need from breath to breath and adjust itself automatically. It is used mainly to treat obstructive sleep apnoea (OSA) — a condition where the soft tissues at the back of the throat sag and block the airway for short spells during sleep. A doctor prescribes an APAP machine; it is not something you buy and set up on your own. (The letters 'APAP' are also used in some countries as shorthand for the painkiller paracetamol/acetaminophen — a completely different thing.)

Yes. Obstructive sleep apnoea is very common — it affects millions of adults worldwide, and many people do not know they have it. Breathing machines like APAP and CPAP are among the most widely used treatments for it.

Sleep apnoea can affect anyone, including children. It is more common in men, in people over 40, in people living with overweight, and in people with a large neck, a small jaw, large tonsils, or a family history of the condition. It also becomes more likely after menopause in women. Children with large tonsils or adenoids can have it too.

Symptoms

Common symptoms

• Loud snoring, often described as disruptive to others in the house
• Pauses in breathing during sleep that a partner notices, followed by a gasp or snort
• Waking up feeling unrefreshed, even after a full night in bed
• Feeling very sleepy or foggy during the day, or falling asleep while watching TV or reading
• Morning headaches and a dry mouth or sore throat
• Poor concentration, forgetfulness or low mood
• Needing to get up to pass urine several times at night
• Irritability or a shorter temper than usual

Symptoms in children

• Snoring most nights, or noisy, effortful breathing in sleep
• Breathing through the mouth rather than the nose
• Restless sleep, sweating heavily at night, or sleeping in odd positions
• Bedwetting that starts again after being dry
• Behaviour changes such as being very tired, easily upset or overactive
• Trouble concentrating or falling behind at school
• Slower growth or poor weight gain in some children

Symptoms in older adults

• Daytime sleepiness that gets put down to 'just getting older'
• Confusion, memory slips or trouble focusing
• Unsteadiness or falls that are more likely when tired
• Getting up often at night to pass urine
• Snoring may be quieter than in younger people, so it is easier to miss
• Irregular heart rhythms or blood pressure that is hard to control

Causes

Main causes

• The muscles and soft tissues at the back of the throat relax in sleep and narrow the airway
• Extra tissue around the neck or throat, often linked with body weight, pressing on the airway
• Shape of the face and jaw — for example a small or set-back lower jaw, or a large tongue
• Blocked nose from allergies, a deviated septum or long-standing sinus problems
• Large tonsils or adenoids, especially in children
• Alcohol or sedative medicines relaxing the throat muscles at night

Risk factors

• Living with overweight or obesity
• Being male
• Being over 40 (risk rises with age)
• A family history of sleep apnoea
• Menopause
• Smoking
• Drinking alcohol close to bedtime
• Taking sedative medicines, sleeping tablets or muscle relaxants
• Medical conditions such as an underactive thyroid, type 2 diabetes, high blood pressure, or heart rhythm problems
• Nasal blockage or long-standing hay fever and allergies

When to see a doctor

See a doctor urgently if:

• You keep falling asleep while driving, or you feel dangerously sleepy during the day
• Your breathing pauses in sleep are long, frequent, or you wake choking
• You have chest pain, fainting, or breathlessness at rest

Book a routine appointment if:

• You snore loudly and feel tired even after a full night's sleep
• Your partner has seen you stop breathing or gasp in your sleep
• You wake with headaches or a dry mouth most mornings
• Your child snores most nights, breathes through the mouth, or is unusually sleepy or struggling at school
• You have high blood pressure that is hard to control, or you have been told your heart rhythm is irregular
• Your APAP machine feels uncomfortable, leaks, or your symptoms are coming back

Diagnosis

A doctor will ask about your sleep, your daytime energy, your health in general, and any medicines you take. They will also ask your partner or bed-sharer what they have noticed. If sleep apnoea seems likely, you will usually be referred to a sleep clinic for a sleep study, which records your breathing, oxygen levels and movement overnight. The results show whether your breathing is being interrupted and how often.

Tests that may be done

• A sleep study at home or in a sleep laboratory, measuring breathing, oxygen levels, heart rate and body position
• Questionnaires about daytime sleepiness and sleep quality
• Measuring height, weight and neck circumference, and checking your blood pressure
• A look inside the nose and throat, and sometimes a referral to an ear, nose and throat specialist
• Blood tests to rule out other causes of tiredness, such as thyroid problems or low iron
• A review of all your medicines, including sleeping tablets and sedatives

What to expect at your appointment

The assessment is painless and mostly involves talking and filling in questionnaires. The sleep study itself means sleeping with a few soft sensors on your finger, chest or face, either at home or in a clinic. Results usually take a few weeks. If sleep apnoea is found, you will normally be offered a trial of breathing therapy, with help choosing a mask and setting the machine to suit you. Follow-up appointments check that it is working and comfortable.

Treatment

Treatment aims to keep your airway open at night so your sleep is no longer broken. The main treatment is breathing therapy with a CPAP or APAP machine, which most people find makes a real difference to their energy and mood once they get used to it. Other approaches — such as losing some weight, avoiding alcohol before bed, treating a blocked nose, or a custom-made mouth guard — can work alongside the machine or, in milder cases, on their own. Your sleep clinic will help you find the mix that suits you.

Self-care at home

• Use your machine every night, including naps, so your body gets a full night of uninterrupted breathing
• Clean the mask cushion and water tub as your clinic advises — usually a quick daily wipe and a weekly wash
• Replace filters, masks and tubing when your supplier or clinic recommends
• Keep the machine below the level of your head so any condensation runs away from you
• Use the humidifier if your nose or throat feels dry
• Try different mask styles and sizes — a good fit makes a big difference
• Sleep on your side if you find you snore more on your back
• Avoid alcohol and sedative medicines close to bedtime, and speak to your doctor before changing any prescribed medicine

Medical treatments

Breathing therapy is the main medical treatment. CPAP and APAP machines deliver filtered air through a mask to hold the airway open. APAP machines adjust the pressure automatically through the night, which some people find more comfortable. A clinic sets the machine up and adjusts settings over time, and you will be supported with mask fitting and troubleshooting. A humidifier can be added if the air feels dry. Other options include a custom-made oral appliance (a mouth guard that holds the jaw slightly forward), which a dentist with training in sleep medicine makes — this can suit milder cases or people who cannot use a mask. Medicines are not usually used to treat sleep apnoea itself, although your doctor may treat related problems such as allergies, nasal blockage or an underactive thyroid. Always ask your doctor or pharmacist before starting or stopping any medicine.

When is surgery considered?

Surgery is not the first choice for most adults, but it can help in certain situations. In children, removing large tonsils and adenoids is often very effective and may cure the condition. In adults, surgery may be considered for a blocked nose, a deviated septum, or jaw and facial shape problems, typically when breathing therapy has not worked or cannot be tolerated. Your specialist team would discuss the benefits and risks with you.

Living with this condition

Most people need a few weeks to get used to sleeping with a mask, and it is normal to have a wobbly start. Try short practice sessions in the evening while awake, and build up. Keep the mask and tubing clean, keep a spare cushion handy, and take your machine with you when you travel — it counts as medical equipment, so it can usually go in the cabin. Expect to feel more awake within days to weeks, though some people need longer.

Lifestyle tips

• Aim for a regular sleep and wake time, including weekends
• Keep your bedroom quiet, dark and cool
• Avoid alcohol in the evening and skip heavy meals late at night
• If you smoke, ask your doctor or pharmacist for support to stop
• Tell your bed partner what you need — quiet, patience with the mask, and a nudge if you fall asleep without it
• Keep a simple note of how you feel each week so you can see progress and share it at follow-up

Diet and exercise

Losing even a modest amount of weight, if you are living with overweight, can reduce sleep apnoea and sometimes lessen the pressure you need from the machine. There is no special 'sleep apnoea diet' — steady, realistic changes work best, such as smaller portions, more vegetables and pulses, and fewer sugary drinks. Regular activity helps too: aim for something you enjoy most days, like walking, swimming or cycling. Try to finish vigorous exercise a couple of hours before bed. Ask your doctor or a dietitian for personalised advice, especially if you have other conditions such as diabetes or high blood pressure.

Mental health and emotional wellbeing

Long-standing broken sleep can wear you down. Many people with sleep apnoea describe low mood, worry, irritability and trouble thinking clearly, and some feel embarrassed about snoring or self-conscious about using a mask. These feelings are common and they usually improve once sleep is treated. Talk to your doctor if low mood, anxiety or hopelessness is affecting your daily life — effective help is available. If you ever have thoughts of harming yourself, contact your local emergency number or a crisis line in your country straight away.

Prevention

Not all sleep apnoea can be prevented, because the shape of your jaw, throat and airway is largely inherited. But you can lower your risk and improve symptoms by keeping to a healthy weight, avoiding alcohol close to bedtime, not smoking, keeping your nose clear if you have allergies, and having any thyroid problem treated. In children, early attention to large tonsils, mouth breathing and allergies can help.

Screening programmes

There is no routine national screening test for sleep apnoea. Instead, doctors look out for it in people with loud snoring plus daytime sleepiness, and in people with hard-to-control blood pressure, an irregular heart rhythm, type 2 diabetes or a high risk of drowsy driving. If any of these apply to you, ask your doctor whether a sleep study would be worthwhile.

Complications

If left untreated

• Continuing daytime sleepiness, which raises the risk of road and workplace accidents
• High blood pressure that is harder to control
• Higher risk of heart rhythm problems, heart attack and stroke over time
• Higher chance of developing type 2 diabetes
• Memory, concentration and mood problems
• Strain on relationships from snoring and broken sleep
• In children, slower growth, behaviour difficulties and learning problems

Long-term outlook

The outlook is good. Sleep apnoea is a well-understood condition with effective treatment, and most people who use breathing therapy consistently notice more energy, better concentration and improved mood within weeks. Many find the mask becomes second nature. Some people need their settings adjusted along the way or lose weight and need less pressure — that is normal. Keep your follow-up appointments and tell your clinic early if something is not working.
