Sleep
Studies
What is the purpose of a sleep
study?
Could snoring kill you? The answer could be in your
finger
tip!
A revolutionary high tech device makes sleep
study available to millions of snorers at the convenience
of their home.
Snoring is one of the signs of a deadly
condition known as sleep apnea. For millions of individuals suffering from yet
undiagnosed apnea going to a sleep lab or a hospital is uncomfortable and in
some cases not practical.
Now a new and unique technology is available to
address many issues of screening and diagnosing sleep apnea to rest. The device
manufactured by Itamar Medical Ltd. Caesarea, Israel is marketed as Watch-PAT
100. Convenience, accuracy and ease of analysis put this device far apart from
others according to Dr. Mansoor Madani, a pioneering surgeon who has done
extensive research on snoring and obstructive sleep apnea. “We have found this
device to be patient friendly as well as physician friendly” Madani adds. It is
so simple to use by our patients and so easy to read. In fact the analysis and
reporting is done automatically. The digital signals are processed
algorithmically and automatic scoring are presented in a comprehensive report
within few minutes from the physicians own computer.
“We have found this device to interfere far less
with patients sleep pattern resulting in much higher sleep efficiency” explains
Dr. Madani who is the chairman of oral and maxillofacial surgery at the Capital
Health System in Trenton N.J. and director of Center for Corrective Surgery in
Bala Cynwyd PA. One of the main problems he has heard repeatedly from thousands
of patients during the last 2 decayed is patient’s reluctance to have a sleep
study in a hospital setting or a laboratory. “Now we can check patient’s apnea
problems in the comfort of their home.
Watch-PAT 100 records and stores data on
removable flashcard media just like your digital camera. The flash card is then
placed in a special portal connected to the doctor’s computer and upon insertion
of the card is auto read and calibrated. The results will be available to
patient the following day.
The automatic algorithm of this special software
detects respiratory events based on the PAT signal amplitude, pulse rate changes
(derived from the PAT signal), and oxygen saturation. The Actigraph together
with additional signals is used for sleep wake staging. The software issues a
detailed report with sleep-wake and respiratory events statistics.
The Watch-PAT 100 is a
self-contained device that is worn on the wrist and uses a non-invasive finger
mounted pneu-optical probe to measure the PAT signal. The recorded signals are
stored in a removable memory card in the device to be downloaded to a computer
for automatic analysis utilizing proprietary algorithms. In addition to the PAT
Signal, the Watch-PAT 100 records oxygen saturation and actigraphy. A fourth
channel, pulse rate, is derived from the PAT Signal.
Snoring is associated with sleep apnea and unfortunately is
not taken seriously in most cases; it is one of the first signs of sleep apnea.
“If with a push of a bottom we can screen our patients for obstructive sleep
apnea we may in fact be able to diagnose and potentially save their life” Says
Dr. Madani who has done laser surgery on thousands of patients and is reporting
on his findings at the upcoming American College of Oral and Maxillofacial
Surgeons annual meeting in Las Vegas Nevada.

Watch-PAT100
The Watch-PAT Sleep study
report consists of two pages. The first page is the patient information,
referring physician and medical evaluation. The second page is the patient’s
sleep study indices and graphic report of the sleep study.
PAT RDI:
PRDI- The PAT detected
Respiratory Disturbance Index, expresses the number of PAT respiratory events
per hour of actual sleep which has been shown to be an accurate estimate of RDI.
The RDI is the recommended
measurement for the severity of Obstructive Sleep Apnea, by the American Academy
of Sleep Medicine (ASSM). The index includes the following respiratory events as
measured by polysomnography:
Apnea: Is cessation of
respiration, during sleep for 10 seconds or more.
Hypopnea: Reduction of
respiration followed by a desaturation of at least 3% or an arousal.
RERA: Obstructive event that
does not meet the criteria for apnea or hypopnea but causes arousal from sleep
(typically seen as flow limitation terminated by an arousal).
PAT AHI:
This Index includes the number of Apnea and Hypopnea events per hour of
actual sleep. The AHI provides additional information about the severity of OSA,
the characteristics of the respiratory events and can contribute to the
treatment decision.
ODI
This index expresses the
number of oxygen desaturation events during an hour of sleep. Desaturation event
is determined as reduction of 4% or more of the oxygen saturation baseline
level. The index includes the events that occurred during sleep time, and it
does not includes events occurred during wake periods.
Snoring is one of the signs of
sleep apnea, a serious & potentially life-threatening condition. Sleep study
can rule that out!
A sleep study (Polysomnography) is a method of
determining the quality of sleep while monitoring changes in oxygen level.
Monitoring your sleep during an overnight visit to the sleep center could
determine whether you just snore or suffer from sleep apnea. A sleep study logs
how your heart, lungs and other parts of your body function while you sleep. The
test may be conducted in a sleep lab or in the privacy of your own home
depending on several factors. For extremely overweight individuals with signs
and symptoms of sleep apnea, a sleep study is normally recommended prior to
surgery. However, sleep studies could be performed following surgery on patients
who do not have symptoms of sleep apnea and their body weight does not exceed
more than 25% of the average.
We will discus
the importance of sleep study during our consultation meeting and you could choose
the timing of it. We recommend all patients have a sleep study done at some
point during their treatment. You must understand that sleep study is only a
diagnostic tool and not a treatment . Once you are diagnosed for having sleep
apnea the most effective way to correct your apnea is weight loss and CPAP.
