Lee Health's Sleep Medicine specialists provide diagnisis and treatment for a wide variety of sleep disorders, including:
People who suffer sleep apnea stop breathing while
they sleep. This can occur several hundred times
a night. Because of sleep apnea, major organs are
deprived of oxygen and can be seriously damaged
over time. Blood pressure can soar between each
breath and the heart may beat irregularly or even stop.
A single apneic episode may last up to 90 seconds and
is manifested in the following three ways:
Obstructive sleep apnea is characterized by very loud
snoring and is intensified by chronic nasal congestion,
enlarged tonsils or obesity. In addition, infants can
experience obstructive sleep apnea because of
physical problems present at birth.
Central sleep apnea occurs when air flow and chest wall
movement stop because of lack of respiratory stimulus
from the brain.
Mixed sleep apnea is a combination of both.
Some symptoms of sleep apnea are excessive snoring,
high blood pressure, excessive daytime sleepiness,
fatigue or poor school or job performance.
Sleep apnea has been targeted as a potential cause of
Sudden Infant Death Syndrome (SIDS). For this reason,
infants considered at risk for SIDS are recommended for
clinical evaluation. Babies may also experience respiratory
problems, which include central and/or obstructive
sleep apnea, and/or esophageal reflux. If the sleep study
reveals the need for home monitoring, parents can receive
information on rental arrangements as well as home
monitoring instruction through the hospital.
An adult family member is allowed to stay at the Sleep
Disorders Center with pediatric patients during evaluation.
Insomnia is a symptom that can be caused by many factors
such as psychological (chronic depression or temporary
stress), environmental (noise) or physiological (chronic
breathing disorder or temporary pain) conditions. Another
common cause of insomnia is misuse and overuse of
When the regular pattern of sleeping or waking is
disrupted, some individuals find that it is difficult to resume
a sleep-wake schedule that fits their needs. This may be
caused by shift work or other changes in schedule. Some
complaints of insomnia or daytime sleepiness may be due
to undiscovered changes in the sleep-wake rhythm
People who have nocturnal myoclonus (periodic leg
movements or muscle spasms) during sleep may not get
proper rest, causing insomnia or excessive sleepiness.
Individuals who are too sleepy during the day and feel
muscular weakness when they are angry, surprised or
amused may have narcolepsy. Sometimes narcoleptics
experience dreams or hallucinations just as they fall
asleep. Narcolepsy often emerges in adolescence and is a
Multiple-Sleep Latency Test (MSLT) is a series of 20-minute naps given every two hours the day following
the sleep study, if indicated, to confirm the diagnosis.
When people have chronic breathing problems or lung
disease, their symptoms often worsen during sleep.
Complete evaluation of such respiratory diseases
sometimes requires measurement of blood oxygenation
In conjunction with the routine overnight sleep
study, patients (predominately children) may also
have esophageal pH monitored for esophageal reflux
