WatchPAT™200 System 1 Operation Manual
1 GENERAL INFORMATION
This manual is part of the WatchPAT™200 system.
1.1 Intended use / Indications for Use
The WatchPAT™200 (WP200) device is a non-invasive home care device for use with
patients suspected to have sleep related breathing disorders. The WP200 is a diagnostic
aid for the detection of sleep related breathing disorders, sleep staging (Rapid Eye
Movement (REM) Sleep, Light Sleep, Deep Sleep and Wake), snoring level and body
position. The WP200 generates a peripheral arterial tonometry ("PAT®") Respiratory
Disturbance Index ("PRDI"), Apnea-Hypopnea index ("PAHI"), PAT sleep staging
identification (PSTAGES) and optional snoring level and body position discrete states
from an external integrated snoring and body position (SBP) sensor. The WP200’s
PSTAGES and SBP provide supplemental information to its PRDI/PAHI. The
WP200’s PSTAGES and SBP are not intended to be used as the sole or primary basis
for diagnosing any sleep related breathing disorder, prescribing treatment, or
determining whether additional diagnostic assessment is warranted.
The WatchPAT™200 device is not indicated for children less than 17 years old.
1.2 Restrictions for Use
1. The WP200 should be used only in accordance with physician’s instructions. For
exclusion criteria see Section 1.3.
2. Only qualified medical personnel may authorize the use of the WP200.
3. Qualified medical personnel must instruct the patients how to attach and use the
WP200 prior to use.
4. In the event of equipment malfunction all repairs should be executed by authorized
Itamar Medical Ltd. personnel or licensed service agents.
5. The eligibility of a patient for a PAT®study is entirely at the discretion of a
physician, and is generally based upon the patient’s medical status.
6. The WP200 system in whole, or in part, may not be modified in any way.
7. The WP200 is used as an aid for diagnostic purposes only, and should not be used
for monitoring.
8. Only suitably trained and qualified personnel should be authorized to prepare the
WP200 equipment prior to use.
9. The WP200 Operation Manual should be carefully studied by the authorized
operators, and kept where it is easily accessible. Periodic review of the Manual is
recommended.
10. Itamar Medical Ltd. makes no representation whatsoever, that the act of reading the
Manual renders the reader qualified to operate, test or calibrate the system.
11. The tracings and calculations provided by the WP200 system are intended as tools
for the competent diagnostician. They are explicitly not to be regarded as a sole
incontrovertible basis for clinical diagnosis.

WatchPAT™200 System 2 Operation Manual
12. In the event that the system does not operate properly, or if it fails to respond to the
controls in the manner described in this Manual, the operator should refer to the
Troubleshooting section. If necessary, contact our service office to report the
incident, and to receive further instructions.
13. The step by step instructions for the patient should be carefully followed when
attaching the unit to the patient.
14. The WP200 device is not indicated for children less than 17 years old.
1.3 Exclusion Criteria
The WatchPAT™200 device should not be used in the following cases:
1. Use of one of the following medications: alpha blockers, short acting nitrates (less
than 3 hours before the study).
2. Permanent pacemaker: atrial pacing or VVI without sinus rhythm.
3. Sustained* non-sinus cardiac arrhythmias.
* In cases of patient having accumulative time of regular R-R intervals of less than 1.5
hours, the WP200 will not have sufficient valid PAT®signal as required to generate a sleep
report.
1.4 Data Generated by the WatchPAT™200 Device
The WatchPAT™200 device generates a PAT®respiratory disturbance index (“PRDI”)
and its derivative, the PAT®Apnea-Hypopnea Index (“PAHI”) and PAT®sleep staging
identification ("PSTAGES"). The PAHI and PRDI are estimates of conventional RDI
and AHI values and REM, DEEP SLEEP, LIGHT SLEEP, and WAKE stages
identification that are produced by polysomnography (“PSG”). The WatchPAT™200
device also generates optional acoustic decibel detector used for snoring level and
body position discrete states from an external integrated snoring and body position
(SBP) sensor.
1.5 Equipment Classification
The WatchPAT™200 device is a Class IIa medical device under MDD 93/42/EEC,
2007/47/EC Annex IX rule 10.

WatchPAT™200 System 9 Operation Manual
2 OVERVIEW
Obstructive sleep apnea syndrome (OSAS) is considered a major public health
problem. The prevalence of the syndrome is estimated at 2% to 5% in the adult
population. It is characterized by recurrent events of complete or partial obstruction of
the upper airways during sleep, often leading to hypoxemia, and/or arousals associated
with sympathetic nervous system activation. The diagnosis and assessment of the sleep
apnea patient is based on the Respiratory Disturbance Index (RDI), the number of
Apneas, Hypopneas and Respiratory Effort Related Arousals (RERA) per hour of
sleep, along with sleep architecture. The common consequences of this sleep disruption
are daytime sleepiness, poor daytime performance and increased vulnerability to
accidents. Cardiovascular complications such as systemic/pulmonary hypertension,
ischemic heart disease and arrhythmias are the major sequel of OSAS in the adult
population.
The WatchPAT™ device is worn on the wrist and is utilizing a plethysmographic
based finger–mounted probe, to measure the PAT®(Peripheral Arterial Tone) signal.
The PAT®signal is a measurement of the pulsatile volume changes in the fingertip
arteries which reflects the relative state of the arterial vasomotor activity, and thus
indirectly the level of sympathetic activation. Peripheral arterial vasoconstriction,
which mirrors sympathetic activation, is shown as attenuation in the PAT®signal
amplitude. The PAT®signal is recorded continuously and stored on an embedded
micro SD card, together with data from a built-in pulse-oximetry sensor (mounted on
an adjacent finger) and an actigraph (embedded in the WatchPAT™200 device).
Following the sleep study, the recordings are automatically downloaded and analyzed
in an offline procedure using the proprietary zzzPAT software.
The zzzPAT algorithms use the four WatchPAT™ channels (PAT®, Pulse Rate,
Oxygen saturation and actigraphy) for the detection of sleep related breathing disorders
and sleep staging (Rapid Eye Movement (REM), Light Sleep, Deep Sleep and Wake).
The zzzPAT uses WatchPAT™device snoring and body position channels (SBP) to
generate snoring level and body position discrete states. The use of SBP is optional and
according to physician preference.
The software issues comprehensive reports of the study, with statistics and graphic
presentation of the results. The whole night data can be viewed and the automatically
detected events can be revised manually.
