WatchPAT™200U System 1 Operation Manual
1 GENERAL INFORMATION
This manual is part of the WatchPAT™200 Unified system.
1.1 Intended Use / Indications for Use
The WatchPAT™200U (WP200U) device is a non-invasive home care device for use with
patients suspected to have sleep related breathing disorders. The WP200U 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 WP200U 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 WP200U's PSTAGES
and SBP provide supplemental information to its PRDI/PAHI. The WP200U'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™200U device is not indicated for children less than 17 years old.
1.2 Restrictions for Use
1. The WP200U 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 WP200U.
3. Qualified medical personnel must instruct the patients how to attach and use the
WP200U 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 WP200U system in whole, or in part, may not be modified in any way.
7. The WP200U 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
WP200U equipment prior to use.
9. The WP200U 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 WP200U 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™200U 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 WP200U is not indicated for children less than 17 years old.
1.3 Exclusion Criteria
The WatchPAT™200U 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 WatchPAT™200U system will not have sufficient valid PAT®signal as required
to generate a sleep report.
1.4 Data Generated by the WatchPAT™200U
The WatchPAT™200U 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™200U 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 WP200U is a Class IIa medical device under MDD 93/42 EEC: 1993 & Amm.
2007/47/EC Annex IX rule 10.

WatchPAT™200U 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 WP200U is worn on the wrist and is utilizing a plethysmographic based finger–
mounted probe that measures 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 same probe measures RED and IR channels used for the measurement of SpO2 signal.
The PAT®and SpO2 signals are recorded continuously and stored on an embedded micro
SD card, together with data from a built-in actigraph (embedded in the WP200U).
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 WP200U 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 WP200U's 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.
