Polysomnography

equipment that is needed to perform polysomnography is divided over certain sections of the human body that need to be measured at the same time. The electromyography or EMG is an electro diagnostic technique that records the electrical activity created by various skeletal muscles. The signals that are going to be analyzed are detections of the activation levels of the different muscles groups. An example for usage of an electromyography during polysomnography is the detection of chin movement to

Sleep is defined as a complex and reversible condition where the body undergoes a period of unresponsiveness to external stimuli. Its main feature is the behavioral quiescence and the reduced unresponsiveness to stimulus on the exterior surfaces. Sleep is triggered and controlled by the central nervous system that uses networks of various neurotransmitters that are localized at a particular region in the brain. The neurotransmitters networks are redundant and any interference with a specific localized

an alternative to polysomnography. For the first time in 1984, the role of history and physical examination in the diagnosis of OSAS was assessed by Brouillete. However, several studies have demonstrated that clinical presentation alone cannot differentiate sleep related breathing disorders such as primary snoring from OSAS. Brietzke SE (Brietzke, Katz et al. 2004) showed that only 55.8% of patients were identified by clinical presentation as OSAS; were confirmed by polysomnography later. This unreliability

fully relaxed. The last and final stage is known as REM sleep, and it occurs about every 90 minutes. You start to breathe faster, your eyes move very rapidly, heart rate goes up, and muscles are paralyzed.2 This is the stage where you dream.1 Polysomnography is a sleep study test that is used to identify any sleep disorders. During the sleep study, thing such as brain waves, oxygen levels, eye movement and heart rate are recorded throughout the entire sleep.3 Snap electrodes are used to record things

Obstructive sleep apnea (OSA) is when someone is experiencing episodes of cessation of breaths during sleep because of their upper airway relaxing and obstructing air flow during sleep. The episodes usually last for ten seconds or greater and is usually accompanied with a decreased oxygen saturation. Although the airway is relaxed and obstructing airflow, the body (brain) is still attempting to breathe. When breathing has resumed from its apneic state, there is usually a loud gasping snore and or

field and RT’s are progressively being called upon to specialize in this zone of care. Polysomnography is a word that comes from the Greek and each term have different meanings. Poly means many, somno means sleep, and graphy means write. This term indicates an assortment of tests carried out on patients while they sleep. Polysomnography is an overnight test, which helps to analyze sleep disorders. Polysomnography analyzes and identifies an assortment of sleep disorders. Currently there are 77 diagnosed

Apnea is defined as the cessation of respiratory airflow. Sleep Apnea is a growing disorder affecting children and adults without discrimination to age, gender, race or sex. There are three main categories of apnea: central, obstructive, and mixed. Although there are many forms of sleeping disorders Central Sleep Apnea(CSA) is classified to be a less common sleeping disorder characterized by life threating health conditions not limited to death if not diagnosed in a timely fashion and treated to

Sleep Apnea Sleep, why do people sleep at all? Why can't we just stay awake? Some biologist suggest that sleep provides the opportunity to conduct self-repair and purge the body of it's waste that has built up during the day's activity. Nevertheless, the body is capable of repairing itself and disposing of wastes during waking hours, so sleep in a way really isn't necessary for routine maintenance (e.g., urinating, etc.). Dr. Quentin Regestein, lead sleep and sleep disorders researcher at

Introduction Positive airway pressure (PAP) is the standard treatment for patients with moderate-to-severe obstructive sleep apnea (OSA); a sleep-related breathing disorder (SRBD) characterized by episodic complete or partial upper airway occlusion during sleep.1 Over the past years, the relationship between SRBD and cardiac arrhythmias have been thoroughly investigated.2-7 Previous studies have shown that obstructive sleep apnea syndrome (OSAS) predisposes to clinically significant nocturnal impairment

Sleep is a subjective phenomenon in which each individual is unique with respect to their interpretation of what normal or good sleep means to them. There has been continuous debate concerning what normal sleep means and how it is defined. It is important to understand that the physiology of sleep is constantly evolving in many individuals. For instance, sleep patterns change as one ages. While children have a greater ratio of NREM sleep in comparison to adults, adults demonstrate a greater ratio
