Sleep Apnea Syndromes: Disorders characterized by multiple cessations of respirations during sleep that induce partial arousals and interfere with the maintenance of sleep. Sleep apnea syndromes are divided into central (see SLEEP APNEA, CENTRAL), obstructive (see SLEEP APNEA, OBSTRUCTIVE), and mixed central-obstructive types.Sleep: A readily reversible suspension of sensorimotor interaction with the environment, usually associated with recumbency and immobility.Polysomnography: Simultaneous and continuous monitoring of several parameters during sleep to study normal and abnormal sleep. The study includes monitoring of brain waves, to assess sleep stages, and other physiological variables such as breathing, eye movements, and blood oxygen levels which exhibit a disrupted pattern with sleep disturbances.Sleep Apnea, Obstructive: A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES. (From Adams et al., Principles of Neurology, 6th ed, p395)Sleep Apnea, Central: A condition associated with multiple episodes of sleep apnea which are distinguished from obstructive sleep apnea (SLEEP APNEA, OBSTRUCTIVE) by the complete cessation of efforts to breathe. This disorder is associated with dysfunction of central nervous system centers that regulate respiration.Sleep, REM: A stage of sleep characterized by rapid movements of the eye and low voltage fast pattern EEG. It is usually associated with dreaming.Sleep Disorders: Conditions characterized by disturbances of usual sleep patterns or behaviors. Sleep disorders may be divided into three major categories: DYSSOMNIAS (i.e. disorders characterized by insomnia or hypersomnia), PARASOMNIAS (abnormal sleep behaviors), and sleep disorders secondary to medical or psychiatric disorders.

In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.Nasal Decongestants: Drugs designed to treat inflammation of the nasal passages, generally the result of an infection (more often than not the common cold) or an allergy related condition, e.g., hay fever. The inflammation involves swelling of the mucous membrane that lines the nasal passages and results in inordinate mucus production. The primary class of nasal decongestants are vasoconstrictor agents. (From PharmAssist, The Family Guide to Health and Medicine, 1993)Tidal Volume: The volume of air inspired or expired during each normal, quiet respiratory cycle. Common abbreviations are TV or V with subscript T.Pilot Projects: Small-scale tests of methods and procedures to be used on a larger scale if the pilot study demonstrates that these methods and procedures can work.Habits: Acquired or learned responses which are regularly manifested.Melatonin: A biogenic amine that is found in animals and plants. In mammals, melatonin is produced by the PINEAL GLAND. Its secretion increases in darkness and decreases during exposure to light. Melatonin is implicated in the regulation of SLEEP, mood, and REPRODUCTION. Melatonin is also an effective antioxidant.Accidents, Traffic: Accidents on streets, roads, and highways involving drivers, passengers, pedestrians, or vehicles. Traffic accidents refer to AUTOMOBILES (passenger cars, buses, and trucks), BICYCLING, and MOTORCYCLES but not OFF-ROAD MOTOR VEHICLES; RAILROADS nor snowmobiles.Logistic Models: Statistical models which describe the relationship between a qualitative dependent variable (that is, one which can take only certain discrete values, such as the presence or absence of a disease) and an independent variable. A common application is in epidemiology for estimating an individual's risk (probability of a disease) as a function of a given risk factor.Asphyxia: A pathological condition caused by lack of oxygen, manifested in impending or actual cessation of life.Acromegaly: A condition caused by prolonged exposure to excessive HUMAN GROWTH HORMONE in adults. It is characterized by bony enlargement of the FACE; lower jaw (PROGNATHISM); hands; FEET; HEAD; and THORAX. The most common etiology is a GROWTH HORMONE-SECRETING PITUITARY ADENOMA. (From Joynt, Clinical Neurology, 1992, Ch36, pp79-80)Neuropsychological Tests: Tests designed to assess neurological function associated with certain behaviors. They are used in diagnosing brain dysfunction or damage and central nervous system disorders or injury.Gagging: Contraction of the muscle of the PHARYNX caused by stimulation of sensory receptors on the SOFT PALATE, by psychic stimuli, or systemically by drugs.Incidence: The number of new cases of a given disease during a given period in a specified population. It also is used for the rate at which new events occur in a defined population. It is differentiated from PREVALENCE, which refers to all cases, new or old, in the population at a given time.Prone Position: The posture of an individual lying face down.Palatal Muscles: The muscles of the palate are the glossopalatine, palatoglossus, levator palati(ni), musculus uvulae, palatopharyngeus, and tensor palati(ni).Chin: The anatomical frontal portion of the mandible, also known as the mentum, that contains the line of fusion of the two separate halves of the mandible (symphysis menti). This line of fusion divides inferiorly to enclose a triangular area called the mental protuberance. On each side, inferior to the second premolar tooth, is the mental foramen for the passage of blood vessels and a nerve.Maximal Expiratory Flow-Volume Curves: Curves depicting MAXIMAL EXPIRATORY FLOW RATE, in liters/second, versus lung inflation, in liters or percentage of lung capacity, during a FORCED VITAL CAPACITY determination. Common abbreviation is MEFV.Phrenic Nerve: The motor nerve of the diaphragm. The phrenic nerve fibers originate in the cervical spinal column (mostly C4) and travel through the cervical plexus to the diaphragm.ROC Curve: A graphic means for assessing the ability of a screening test to discriminate between healthy and diseased persons; may also be used in other studies, e.g., distinguishing stimuli responses as to a faint stimuli or nonstimuli.Nose Diseases: Disorders of the nose, general or unspecified.Depression: Depressive states usually of moderate intensity in contrast with major depression present in neurotic and psychotic disorders.Cognition Disorders: Disturbances in mental processes related to learning, thinking, reasoning, and judgment.Body Temperature: The measure of the level of heat of a human or animal.Arrhythmias, Cardiac: Any disturbances of the normal rhythmic beating of the heart or MYOCARDIAL CONTRACTION. Cardiac arrhythmias can be classified by the abnormalities in HEART RATE, disorders of electrical impulse generation, or impulse conduction.Reflex: An involuntary movement or exercise of function in a part, excited in response to a stimulus applied to the periphery and transmitted to the brain or spinal cord.Blood Pressure Monitoring, Ambulatory: Method in which repeated blood pressure readings are made while the patient undergoes normal daily activities. It allows quantitative analysis of the high blood pressure load over time, can help distinguish between types of HYPERTENSION, and can assess the effectiveness of antihypertensive therapy.Glottis: The vocal apparatus of the larynx, situated in the middle section of the larynx. Glottis consists of the VOCAL FOLDS and an opening (rima glottidis) between the folds.Humidity: A measure of the amount of WATER VAPOR in the air.Magnetic Resonance Imaging: Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.Single-Blind Method: A method in which either the observer(s) or the subject(s) is kept ignorant of the group to which the subjects are assigned.Electrocardiography, Ambulatory: Method in which prolonged electrocardiographic recordings are made on a portable tape recorder (Holter-type system) or solid-state device ("real-time" system), while the patient undergoes normal daily activities. It is useful in the diagnosis and management of intermittent cardiac arrhythmias and transient myocardial ischemia.Craniofacial Abnormalities: Congenital structural deformities, malformations, or other abnormalities of the cranium and facial bones.Pulmonary Medicine: A subspecialty of internal medicine concerned with the study of the RESPIRATORY SYSTEM. It is especially concerned with diagnosis and treatment of diseases and defects of the lungs and bronchial tree.Nitrazepam: A benzodiazepine derivative used as an anticonvulsant and hypnotic.Brain: The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.Ventricular Dysfunction: A condition in which HEART VENTRICLES exhibit impaired function.

  • When someone has sleep apnea, oxygen levels in the body may fall and sleep can be disrupted. (
  • Less commonly, sleep apnea can happen when someone doesn't get enough oxygen during sleep because the brain doesn't send signals to the muscles that control breathing. (
  • Sleep apnea disrupts how your body takes in oxygen, which makes it hard for your brain to control how blood flows in your arteries and the brain itself. (
  • Complete closure can lead to apnea while partial closure allows breathing but decrease the intake of oxygen (hypopnea). (
  • When the oxygen in your blood falls during breathing pauses, it signals your brain to wake up very briefly and draw a breath," says Clete Kushida, medical director of the Stanford Sleep Medicine Center. (
  • This lack of breathing for ten seconds is enough to cause the oxygen level to drop in the blood and to cause one to go from deep sleep into light sleep. (
  • Pauses and periods of obstruction can lead to drops in blood oxygen levels, arousals from sleep and fragmented sleep. (
  • Diagnosis and severity of sleep apnea were determined using overnight polysomnography, or a "sleep study," which records brain waves, blood oxygen levels, breathing, heart rate and eye and leg movements during sleep. (
  • A new study shows that compared to people who do not have the disorder, those who suffer from sleep apnea may not be capable of burning sufficiently high levels of oxygen during strenuous aerobic exercise. (
  • Researchers found that people who suffer from obstructive sleep apnea - a condition where breathing stops and starts during sleep - are also likely to have a lower peak oxygen uptake during aerobic activity. (
  • people with moderate to severe obstructive sleep apnea appear to have a lower peak oxygen uptake during aerobic activity compared to people who do not suffer from the sleep disorder. (
  • I do not have sleep apnea but my oxygen levels were so low that I now have to wear oxygen at night. (
  • But the sleep doctor also analyzes other data, such as oxygen saturation. (
  • These episodes can interfere with sound sleep, reduce the flow of oxygen to vital organs, and cause heart rhythm irregularities . (
  • During the test, a variety of body functions, such as the electrical activity of the brain, eye movements, muscle activity, heart rate, breathing patterns, air flow, and blood oxygen levels are recorded at night during sleep. (
  • It records fewer body functions than PSG, including airflow, breathing effort, blood oxygen levels and snoring to confirm a diagnosis of moderate to severe obstructive sleep apnea. (
  • We were not able to confirm previous hypotheses that obstructive sleep apnea is a cause of overall cancer development through intermittent lack of oxygen," said lead author Dr. Tetyana Kendzerska, from the Institute for Clinical Evaluative Sciences and Women's College Hospital at the University of Toronto. (
  • Although no link was seen for cancer in general, the researchers did find that low oxygen levels related to sleep apnea were associated with smoking -related cancers, such as lung cancer . (
  • OSA is defined as periodic episodes of nocturnal airflow restriction (hypopneas) or obstruction (apneas) in association with sleep disruption, arousals from sleep, oxygen desaturation, and possible hypercapnia [ 4 ]. (
  • Sleep-disordered breathing is characterized by cycles of apnea-induced hypoxia, where the sleeper experiences a temporary drop in oxygen levels. (
  • Earlier studies by the Technion scientists suggest apnea increases oxygen-related stress and inflammation in the heart and blood vessels. (
  • This could occur many times at night and affect oxygen supply to vital parts that make obstructive sleep apnea a condition for which there are cures and machines to stop breath cessation and snoring. (
  • In the pediatric age range, abnormalities include oxygen desaturation under 92%, more than one obstructive apnea per hour, and elevations of ET CO 2 measurements of more than 50 mm Hg for more than 9% of sleep time or a peak level of greater than 53 mm Hg. (
  • It monitors brain waves, eye movement, breathing, and oxygen levels in the blood, as well as snoring and gasping sounds during sleep. (
  • The researchers analyzed the treatment's effect on patients' oxygen levels, sleep apnea symptoms and overall quality of life. (
  • People with obstructive sleep apnea can stop breathing dozens or hundreds of times each night leading to sleep disruption and low levels of oxygen. (
  • The interruptions in breathing that characterize sleep apnea lead to low oxygen levels in the blood and brain. (
  • Sleep apnea triggers a series of responses in the body as a result of low oxygen levels," Ramos said. (
  • Hypertension associated with sleep apnea occurs because of the strain that low oxygen levels in the blood and brain place on the cardiovascular system. (
  • Although sleep apnea causes low oxygen levels in the body and leads to a host of other complications, the sleep disorder itself is not fatal and does not directly cause stroke. (
  • It is important to note that the effect of sleep apnea on the circulatory system and all the bodily processes associated with low oxygen levels and hypertension will not put people at risk for stroke from one day to the next. (
  • To eliminate the potential for strokes and other risks associated with low oxygen levels in the body, sleep apnea must be treated. (
  • Though the specific connection between dementia and sleep is unclear, Edelmayer said it might be that the brain gets less oxygen during apnea episodes, and that stresses the brain. (
  • With that, we can determine how many times you stop breathing, for how long, how low your oxygen goes, if you stop breathing because you've got obstruction intermittent in your throat, which is the most common form of sleep apnea or if you stop breathing because essentially your brain doesn't send the signal. (
  • After diagnosis, a memory card inside the machines patients sleep with will help Reinoso monitor sleep patterns and even adjust the flow of oxygen from in his office, without seeing the patient. (
  • Although sleep fragmentation and duration were not related to the odds of developing cognitive impairment, two measures of hypoxia -- an elevated oxygen desaturation index and a high percentage of sleep time in apnea or hypopnea -- were associated (ORs 1.98 and 2.32, respectively). (
  • People with sleep apnea don't take in enough oxygen. (
  • Sleep apnea is associated with decreased oxygen saturation in your blood. (
  • Central sleep apnea (CSA) or central sleep apnea syndrome (CSAS) is a sleep-related disorder in which the effort to breathe is diminished or absent, typically for 10 to 30 seconds either intermittently or in cycles, and is usually associated with a reduction in blood oxygen saturation. (
  • Breathing is regular in a healthy person during sleep, and oxygen levels and carbon dioxide levels in the bloodstream stay fairly constant: After exhalation, the blood level of oxygen decreases and that of carbon dioxide increases. (
  • After the episode of apnea, breathing may be faster and/or more intense (hyperpnea) for a period of time, a compensatory mechanism to blow off retained waste gases, absorb more oxygen, and, when voluntary, enable a return to normal instinctive breathing patterns by restoring oxygen to the breathing muscles themselves. (
  • During a PSG (polysomnography) (a sleep study), a person with sleep apnea shows breathing interruptions followed by drops/reductions in blood oxygen and increases in blood carbon dioxide level. (
  • Men, people who are overweight, and people who are older than 40 years of age are more likely to have sleep apnea. (
  • You are more at risk for sleep apnea if you are overweight, male, or have a family history or small airways. (
  • Risk factors include overweight, abnormalities in the structure of the nose or throat and a family history of apnea. (
  • Sleep apnea can affect people of all ages, including babies and children and particularly people over the age of fifty and those who are overweight. (
  • According to a study performed by the National Heart, Lung, and Blood Institute, more than 50 percent of those with obstructive sleep apnea are actually obese or overweight. (
  • People who are overweight are more likely to develop sleep apnea. (
  • In the case of people who are not overweight, sleep apnea can be caused by having a long tongue, a narrow jaw, or a long uvula, which is the punching-bag looking tissue that hangs from the back of the throat. (
  • For overweight patients, the solution to sleep apnea and all the associated risks is losing weight. (
  • These findings underscore the need to prevent sleep apnea and screen for sleep apnea in patients particularly at risk for developing diabetes - e.g., overweight and physically inactive people," he told Reuters Health by email. (
  • Some patients had clinically significant sleep apnea despite lack of sleep complaints. (
  • Children and adolescents with significant sleep apnea should avoid eating large amounts just before bedtime. (
  • In general, nasal surgery alone is insufficient to treat significant sleep apnea. (
  • Alcohol, sedatives and tranquilizers may also promote sleep apnea by relaxing throat muscles. (
  • Obstructive sleep apnea is caused by a narrowing or collapse of throat tissues during sleep . (
  • If the passage is narrow, relaxation of throat muscles during sleep can obstruct, or block, the passage and hinder or prevent air from flowing into the lungs. (
  • Until very recently, the only treatments with any real track record were throat surgery and a sleep machine with a face mask that many compared to Darth Vader's. (
  • In OSA, the pharynx (throat) repeatedly collapses during sleep. (
  • Because we inherit certain physical characteristics of the throat, there also appears to be a genetic predisposition to sleep apnea. (
  • Tests include a fiber optic camera examination of the portions of the nose and throat not able to be seen with standard in-office examination, a sleep study (polysomnogram) or a sedated procedure called sleep endoscopy. (
  • Obstructive sleep apnoea (OSA) is a relatively common condition where the walls of the throat relax and narrow during sleep, interrupting normal breathing. (
  • It's normal for the muscles and soft tissues in the throat to relax and collapse to some degree while sleeping. (
  • This is the most common form of sleep apnea caused by the muscles in the throat relaxing. (
  • person is lying on back, face up) and in obstructive sleep apnea (B). The arrows indicate complete obstruction in the back of the throat. (
  • She may refer you to an otolaryngologist (an ear, nose, and throat specialist), a pulmonologist (a lung specialist), a sleep expert, or an apnea expert. (
  • For some people, treatments needed to manage the condition are lifestyle changes like losing weight, stopping smoking, sleeping on the side instead of the back as well as avoiding medicines and alcohol that cause drowsiness and make it more difficult for the throat to stay open during sleep. (
  • Generally, surgery involves widening the breathing passages, shrinking removing or stiffening the excess tissue in the throat or mouth or even resetting the lower jaw to better facilitate breathing during sleep, according to the NHLBI. (
  • But less than 5 events of hypopnea and apnea together is considered normal on the Apnea Hypopnea Index. (
  • Sleep-disordered breathing was assessed with the Apnea Hypopnea Index (AHI) and the Respiratory Distress Index (RDI). (
  • The HeartBEAT trial included 318 patients with cardiovascular disease or multiple cardiovascular risk factors recruited from cardiology practices and an apnea-hypopnea index (AHI) of 15 to 50 events per hour, diagnosed with home sleep testing after a positive screen with the Berlin questionnaire. (
  • A study can establish reliable indices of the disorder, derived from the number and type of event per hour of sleep (Apnea Hypopnea Index (AHI), or Respiratory Disturbance Index (RDI)), associated to a formal threshold, above which a patient is considered as suffering from sleep apnea, and the severity of their sleep apnea can then be quantified. (
  • The Apnea-Hypopnea Index (AHI) is expressed as the number of apneas or hypopneas per hour of sleep. (
  • This is one of the first studies to show real-time effects of sleep apnea on metabolism during the night," said study senior author Dr. Jonathan Jun, an assistant professor of medicine at Johns Hopkins University School of Medicine in Baltimore. (
  • It's possible that the stroke risk is related to cumulative effects of sleep apnea adversely influencing health over many years," said Susan Redline, M.D., MPH, professor of medicine, pediatrics, and epidemiology and biostatistics, at Case Western Reserve University in Cleveland and lead author of the paper. (
  • What Are the Effects of Sleep Apnea? (
  • Lifestyle changes such as losing weight, quitting smoking and avoiding alcohol can reduce severity of sleep apnea. (
  • The greater the severity of sleep apnea, the higher the likelihood of depressive symptoms, the researchers found. (
  • The incidence and severity of sleep apnea we observed among survivors of acute respiratory failure, if replicated in larger studies, are cause for concern," said Dr. Parsons. (
  • There is increasing evidence that sleep apnea may lead to liver function impairment, particularly fatty liver diseases (see steatosis ). (
  • But he said the results provide more evidence that sleep apnea isn't just a manifestation of diabetes and cardiovascular disease, it can make these conditions worse. (
  • There is also mounting evidence that sleep apnea can cause impairment to one's liver function. (
  • Some people who have sleep apnea only learn about it from their partners. (
  • People who have sleep apnea stop breathing for 10 to 30 seconds at a time while they are sleeping. (
  • Nine out of 10 people who have sleep apnea have this type of apnea. (
  • It helps most people who have sleep apnea. (
  • People who have sleep apnea will stop breathing repeatedly throughout their sleep cycle. (
  • Most of what I've read and been told by the people at the sleep clinic, is that people who have sleep apnea don't go into REM sleep and don't dream. (
  • The American Academy of Dental Sleep Medicine (AADSM) is a professional society for dentists who help patients control snoring and obstructive sleep apnea through the use of oral appliance therapy. (
  • Sleep studies are painless and risk-free, but patients usually need to spend the night in a hospital or sleep center. (
  • New data not only confirm this finding, but show that sleep apnea patients are at very high risk of serious, life-threatening car wrecks. (
  • Alan Mulgrew, MD, and colleagues at the University of British Columbia in Vancouver compared the claims and accident records of 800 patients with confirmed sleep apnea with those of 800 people who did not have sleep apnea. (
  • No matter what you try to account for, sleep apnea patients still have these serious crashes in threefold excess," Mulgrew tells WebMD. (
  • When we looked at the small number of truly awful crashes -- head-on collisions and collisions with pedestrians or cyclists -- 80% of the crashes of that kind were in sleep apnea patients. (
  • All sleep apnea patients appeared to be at risk of crashing their cars. (
  • Patients who said they drove even when they felt sleepy were no more likely than other sleep apnea patients to wreck their cars. (
  • The results of the study were so striking that Mulgrew now carefully asks his sleep apnea patients about their driving histories and about any "near misses" they might be having. (
  • While evaluating older, obese men for a sleep apnea study, Botros and his Yale colleagues noticed that about a third of the patients suffered from diabetes as well as sleep apnea. (
  • To see whether the two conditions were related, the researchers kept track of nearly 600 sleep apnea patients for up to six years. (
  • Compared with similar men without sleep apnea, the patients were more than two-and-a-half times more likely to develop diabetes. (
  • The more severe the sleep apnea, the higher the patients' risk of diabetes. (
  • Schulman explains patients with sleep apnea are not aware of most arousals. (
  • Although sleep apnea is diagnosed by a positive overnight sleep study, fewer than 8 of the 10,000 patients at these practices had been referred for a sleep study in the previous year, though it would be expected that as many as 1,700 of them had sleep apnea. (
  • When physicians did receive training about sleep apnea, the number of patients they sent for sleep apnea testing increased dramatically. (
  • A number of studies have also shown that patients with severe sleep apnea are at a two- to seven-fold increased risk of having an automobile accident. (
  • AMSTERDAM - Patients with migraine, especially chronic migraine, are at increased risk for sleep disturbances, including sleep apnea (SA), a new study suggests. (
  • Sleep apnea risk for the patients with CM also rose with increasing BMI. (
  • On average, patients with EM got 6.8 hours of sleep per night and those with CM got 6.4 hours. (
  • DENVER - An implantable pacemaker-like device that controls breathing muscles during sleep by electrical stimulation of a phrenic nerve proved effective in patients with moderate to severe central sleep apnea (CSA) in a randomized controlled trial. (
  • The authors note that there is increasing interest in using CPET as a way to categorize sleep apnea patients in terms of heart risk. (
  • However, lead author Jeremy Beitler, assistant clinical professor in pulmonary and critical care medicine at UCSD, and colleagues suspect that using CPET and VO2 max in this way with sleep apnea patients may not be as straightforward as it might seem. (
  • But the team found patients with sleep apnea had reduced aerobic fitness even when compared with people of similar body mass index. (
  • Sleep apnea can put surgical patients at high risk for respiratory complications during and after surgery. (
  • Whether you currently treat sleep apnea patients or are considering adding these procedures to your practice, this webinar will provide essential information required to obtain appropriate reimbursement from medical payers. (
  • Certain physical traits and clinical features are common in patients with obstructive sleep apnea. (
  • Central sleep apnea is usually observed in patients with central nervous system dysfunction, such as following a stroke or in patients with neuromuscular diseases like amyotrophic lateral sclerosis . (

  • The Sleep Apnoea Trust Association (UK) - The Sleep Apnoea Trust Association (SATA) exists to improve the lives of sleep apnoea patients, their partners and their families.Managed entirely by volunteers, SATA is the leading UK charity working in the field of sleep apnoea. (
  • Among the 14 patients who underwent polysomnography, the majority met criteria for clinically-relevant sleep apnea, with 13 having an RDI of 15 or greater and 10 having an AHI of 15 or greater. (
  • Evaluating and treating sleep apnea may significantly impact the health and well-being of these patients. (
  • For the new study, Jun and his colleagues monitored 31 obese patients with an average age of 51 as they slept. (
  • In a university news release, Jun said because only obese patients were observed in this study, findings may not apply to all people with sleep apnea, and further studies are needed. (
  • For the study, Kendzerska and colleagues studied about 10,150 patients suffering from sleep apnea who took part in a sleep study between 1994 and 2010. (
  • The quality of life of sleep apnea patients with cancer and their ability to tolerate treatments such as chemotherapy and radiation can be very different than those without the condition," he said. (
  • Lavie, along with researchers Dr. Slava Berger, Prof. Doron Aronson and Prof. Peretz Lavie, looked for clues to this puzzle in 40 male patients - a mix of healthy sleepers and those with sleep disordered breathing, who had had a heart attack just a few days earlier. (
  • Blood samples drawn from these patients revealed that the sleep disordered breathing patients had markedly higher levels of endothelial progenitor cells (EPCs), which give rise to new blood vessels and repair the injured heart, than the healthy sleepers. (
  • Patients with sleep-disordered breathing, they noted "are essentially better prepared to harness the recruitment of EPCs when [a heart attack] comes knock at the door. (
  • It should be further investigated if inducing intermittent hypoxia immediately after a heart attack, in patients without sleep disordered breathing, will also have such an effect," Lena Lavie said. (
  • In 59 percent of these patients, blood pressure was normalized by using an oral appliance to treat sleep apnea. (
  • For those of you who have serious apnea issues Sleep Apnea Machine can do the right tricks as the machines have proven to be effective for patients with serious problems. (
  • Until we have further evidence on the efficacy of medical cannabis for the treatment of sleep apnea, and until its safety profile is established, patients should discuss proven treatment options with a licensed medical provider at an accredited sleep facility," said statement lead author Dr. Kannan Ramar. (
  • Poor eating habits among families contribute to child obesity, and some of Naqvi's adolescent and teenage patients suffer from sleep apnea for the reasons a middle-aged person would. (
  • Ramos tells his patients to take care of their sleep and to adopt good sleep habits - no caffeine close to bedtime, no watching television in bed, darken the room and set the thermostat at a comfortable temperature to keep from tossing and turning. (
  • however, since home testing can give false negative readings in 10 to 20 percent of patients, a negative home test should be followed up with a laboratory sleep study if the suspicion for sleep apnea is high. (
  • The findings support recommendations from the International Diabetes Federation that patients with one condition be screened for the other, too, the research teams notes in the journal Sleep Medicine. (
  • Patients are at risk for heart attacks, stroke, and sleep apnea can make it more difficult to control diabetes. (
  • The trial by Chirinos and colleagues included 181 obese patients with moderate-to-severe obstructive sleep apnea (an AHI of at least 15 events per hour as screened by home sleep testing and confirmed by lab testing) and serum CRP levels greater than 1.0 mg/L. (
