Using a CPAP Machine to Sleep Better

The many advances and innovations in medical technology have helped improve the performance of continuous positive airway pressure (CPAP) machine. Familiar to those suffering from obstructive sleep apnoea (OSA) and other related sleep apnoea problems, a CPAP machine helps these people to breathe easily and regularly at night.

A person with OSA has a narrow airway or a collapsed airway during sleep. This condition causes the oxygen level to decrease, triggering the brain to briefly nudge the sleeping person to wake in order to re-open the collapsed airway. This event happens hundreds of time during sleep, not only disrupting the person’s sleep but also increases the body’s stress that could lead to co-morbidities such as diabetes, hypertension, stroke and heart attack.… Read More...

CPAP Therapy and Longer Life for Sleep Apnoea Patients

Great news for the millions of people who are undergoing continuous positive airway pressure (CPAP) therapy using a mask.  An 11-year study indicated that the use of CPAP mask was directly linked to a 62% decline in the odds for death.

The study was led by Dr. Quentin Lisan and conducted at the Paris Cardiovascular Research Center.  Dr. Lisan said that the benefit was sustained even after factoring the usual co-morbidities of sleep apnoea such as diabetes, obesity, high blood pressure, and diabetes.

Previous studies regarding the connection between CPAP therapy and longevity was not established since those clinical trials were simply too short.… Read More...

Sleep Apnoea: Long Term Prognosis

Most diseases are curable by taking medications, but in some cases medications or therapy may only control or regulate some diseases.  What then is the long-term prognosis for sleep apnoea? Can a person with sleep apnoea can hope to be totally free from it?

What Causes Sleep Apnoea?

Obstructive sleep apnoea is due to the collapse of a part of the airway starting from the nose and ending up on the lungs, collapses during sleep.  Breathing is repeatedly disrupted for 10 seconds or more all through the night.

The most common cause of obstructive sleep apnoea (OSA) in adults is obesity and excess weight, which is linked with the soft tissue of the throat and mouth.… Read More...

Sleep Apnoea and Pulmonary Hypertension

Pulmonary hypertension (PH) is a grave and rare lung disease that directly affects the pulmonary arteries, leading to elevated blood pressure. The disease causes the thickening and narrowing of the arteries that pump blood into the heart’s right ventricle. Thus, the heart of a person with PH tends to be highly stressed, which could lead to conditions such as weakened and enlarged heart, angina, and eventually heart failure.

Pulmonary Hypertension

Sleep apnoea could be considered as a potentially critical sleep disease that causes a patient to repeatedly stop breathing for short periods during sleep. Sleep apnoea is one of the most common triggers for the development of pulmonary hypertension.… Read More...

Sleep Apnoea: Risk Factors During Pregnancy

In a recent study done by researchers at the National Institutes of Health (NIH) in the United States, it was found that older pregnant women who are overweight and who snore have an increased risk of developing interrupted breathing or sleep apnoea. The study was published in the American Journal of Obstetrics and Gynecology, and endorsed by the National Heart, Lung, and Blood Institute and NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD).

According to NICHD’s Pregnancy and Perinatology Branch’s Uma Reddy, M.D., the study opened the door for very affordable means to screen and test large numbers of women who are at a higher risk of developing sleep apnoea during pregnancy.  … Read More...

Non-Compliance to CPAP Therapy Linked to Hospital Readmission

A recent study of patients with obstructive sleep apnoea (OSA), implies that non-compliance to continuous positive airway pressure (CPAP) therapy is notably linked with increased 30-day readmission to a hospital facility.

The study shows that non-compliant patients are 3.5 times more probable to be readmitted to the hospital within a span of 30 days. These non-adherent patients are 2 times more likely to be readmitted to the hospital for cardiovascular conditions such as congestive heart failure, myocardial ischemia, and atrial fibrillation which are closely related to untreated obstructive sleep apnoea.

Dr. Behrouz Jafari is the lead study investigator and the director of Veteran Affairs Long Beach Healthcare System in Long Beach, California.… Read More...

Different Types of Sleep Study

Polysomnogram (PSG), commonly known as sleep study, is a dedicated method to monitor the various physiological changes in the body while one is sleeping.  This type of study helps sleep doctors investigate and diagnose sleep disturbance that occur during sleep.  These sleep disturbances may be medical conditions that cause daytime sleepiness and tiredness, disrupted sleep, memory lapses, lost of concentration and other comorbidities that are linked to lack of sleep.

PSG is a non-invasive procedure. The sensors used may cause minor skin irritations to some but the discomfort is insignificant.  Comfort and safety of patients during the testing are ensured as trained and qualified staff are on duty during the diagnostic test.… Read More...

Untreated Sleep Apnoea Linked to Damaged Brain Cells of Children

Children diagnosed with sleep apnoea but are not undergoing CPAP therapy may exhibit delayed brain development.

A study led by Dr. Leila Kheorandish-Gozal of the University of Chicago indicated that children suffering from moderate to severe obstructive sleep apnoea could have damaged to brain cells. The test subjects showed a significant reduction of gray matter brain cells involved in memory, movement, speech, emotions, self-control, decision-making, and perception, when compared with children of the same age who do not have sleep apnoea.

Statistics indicate that up to 5% of children are affected by sleep apnoea. This study finally linked sleep apnoea and delayed neuronal growth in a child’s developing brain. … Read More...

Sleep Apnoea Increases Risk of Dementia

Obstructive sleep apnoea (OSA) is a common sleep disorder that interrupts breathing during sleep. A recent study pertaining to obstructive sleep apnoea and its link to dementia was recently published in the European Respiratory Journal.

The study indicated that changes in the brain during sleep apnoea episodes are directly linked to changes in the structure of the brain seen in elderly people with signs of early dementia.  Scientists at the University of Sydney’s Brain and Mind Center said that new findings indicate that oxygen deprivation during sleep could be tied to alterations in the brain’s temporal lobes and compromised ability to absorb new information.… Read More...

The Link between Sleep Apnoea and Insomnia

Sleep apnoea and insomnia are both classified as sleeping disorders.  The two conditions have been classified; that accepted sleep medicine view is that obstructive sleep apnoea (OSA) and chronic insomnia are separate disorders.  However, there are now evidences that support the belief that these two sleeping disorders overlap.

A study about comorbid insomnia and obstructive sleep apnoea indicated that 39% up to 58% of OSA patients are also suffering from insomnia. The study showed that 43% of elderly people diagnosed with chronic insomnia have undiagnosed OSA.
