There are three types of sleep apnea: obstructive,central and mixed.OBSTRUCTIVE SLEEP APNEA, <strong>the</strong> most common,is caused by a blockage of <strong>the</strong> airway, usuallywhen <strong>the</strong> soft tissue in <strong>the</strong> rear of <strong>the</strong> throatcollapses during sleep.CENTRAL SLEEP APNEA, so called because itrelates to <strong>the</strong> function of <strong>the</strong> central nervoussystem, occurs when <strong>the</strong> airway is not blockedbut <strong>the</strong> brain fails to signal <strong>the</strong> muscles tobrea<strong>the</strong> because of instability in <strong>the</strong> respiratorycontrol center.MIXED OR COMPLEX SLEEP APNEA, as <strong>the</strong>name implies, is a combination of obstructiveand central.❋ The Sleep StudyIf you suspect you may have sleep apnea, discussit with your primary care physician. Your physicianmay suggest you undergo a sleep study orpolysomnogram at a sleep lab. The test monitorsyour brain waves, heartbeat and breathing asyou sleep. It also records your eye and leg movementsas well as muscle tension.• During a sleep study, sensors that send tiny electrical signalsto a computer are placed on your head, face, chest andlegs. Those electric signals become data that are analyzed bya qualified physician to determine whe<strong>the</strong>r you have sleepapnea or any o<strong>the</strong>r sleep disorder. You will not feel any painduring <strong>the</strong> study. The sensors are placed gently on your skinand connected to a computer. The wires are long enough tolet you move around and turn over in bed.<strong>MGH</strong> HasSolutions<strong>Marion</strong> <strong>General</strong> <strong>Hospital</strong> has anew sleep lab, convenientlylocated at 1387 N. Baldwin Ave.,which can help diagnose sleepapnea and o<strong>the</strong>r sleep disorders.Corey Mettler, <strong>MGH</strong> sleeplab manager, knows <strong>the</strong> advantages that continuous positive airwaypressure, or CPAP, offers patients. “Many patients have told me it’s <strong>the</strong>best thing that has ever happened to <strong>the</strong>m,” he says. “They can onceagain function throughout <strong>the</strong> day without taking naps or falling asleepat inappropriate times.”<strong>MGH</strong>’s warm and inviting sleep study rooms have been designed foryour comfort, complete with queen-size beds; flat-screen televisionswith remote; large, puffy pillows; fans; private bathrooms; and hotel-likedecor—all <strong>the</strong> comforts of home when away from home.• A technician will run a short check on <strong>the</strong> quality of <strong>the</strong>signals prior to starting <strong>the</strong> study. The lights are <strong>the</strong>n turnedout and you will be asked to try to fall asleep. An infraredvideo camera allows a technologist to see you and recordyour activity from a nearby room during <strong>the</strong> test, which usuallytakes place overnight. Daytime studies are available forshift workers.• If your initial results show a significant amount of sleepdisordered breathing, you will be asked to return for a secondstudy where continuous positive airwaypressure, or CPAP, will be used. During thisphase, you will wear a nasal mask that deliversincreased air pressure into your airway in anattempt to open <strong>the</strong> airway and alleviate yourproblematic breathing.Can you remember <strong>the</strong> last time you feltfully rested?
