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"), Central Apnea-Hypopnea index ("PAHIc"),
PAT sleep staging identification (PSTAGES) and optional snoring level and body position
discrete states from an external integrated snoring and body position sensor. The WP200U's
PSTAGES and snoring level and body position provide supplemental information to its
PRDI/PAHI/PAHIc. The WP200U's PSTAGES and snoring level and body position 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.
PAHIc is indicated for use in patients 17 years and older. All other parameters are indicated
for 12 years and older.
1.2 Restrictions for Use
1. The WP200U should be used only in accordance with physician’s instructions. For
precautions see Section 1.3.
2. Only qualified medical personnel may authorize the use of the WP200U.
3. Qualified medical personnel must instruct the patients (and accompanying individual
if needed) 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.

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 the setting of sustained arrhythmia the WatchPAT’s automated algorithm might
exclude some periods of time, resulting in a reduced valid sleep time. A minimum
valid sleep time of 90 minutes is required for an automated report generation.
4. The WP200U is not indicated for children who weigh less than 65 lbs.
1.4 Additional Precautions specific to pediatric use
The WatchPAT™200U is indicated for use in patients 12 years and above.
The following Precautions and Notes are referring to pediatric aged 12-17 years.
Precautions:
1. Pediatric patients with severe comorbidities such as Down syndrome, neuromuscular
disease, underlying lung disease or obesity hypoventilation should be considered for
sleep study in a laboratory polysomnograph (PSG) rather than a home sleep testing
(HST).
2. It is recommended that the physician makes sure that the patient and his/her guardian
are aware that the use of specific drugs and other substances used to treat ADHA,
antidepressants, corticosteroids, anticonvulsants, use of caffeine, nicotine, alcohol
and other stimulants might interfere with sleep and affect the sleep study's conditions.
Notes:
1. PAT Respiratory Disturbance Index (PRDI) is indicated for patients 17 years of age
or greater

WatchPAT™200U System 3 Operation Manual
2. The snoring and body position safety and effectiveness was not validated on pediatric
patients
3. Special attention on training the pediatric patient and / or his accompanying
individual on use and placement of the device prior to initiating a sleep study with
the WatchPAT™ device (for further details see section 7 and section 8)
1.5 Data Generated by the WatchPAT™200U
The WatchPAT™200U generates a PAT respiratory disturbance index (“PRDI”) , PAT Apnea-
Hypopnea Index (“PAHI”), PAT central Apnea-Hypopnea Index (pAHIc), percentage of total
sleep time with Cheyne-Stokes Respiration pattern (%CSR) and PAT sleep staging identification
("PSTAGES"). The WP200U respiratory indices and sleep stages are estimates of conventional
values and 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/RESBP) sensor.

WatchPAT™200U System 10 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). Snoring
and Body Position signals are generated from the SBP/RESBP integrated sensor (optional).
The RESBP (Respiratory Effort Snoring and Body Position) sensor records the subject’s
chest movement signal in addition to the snoring and body position signals that are
included with the SBP sensor.
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). In WP200U
only, for further identification of central apnea the respiratory movement channel generated
from the RESBP sensor is used in the zzzPAT algorithm in addition to the other channels.
The zzzPAT uses WP200U's snoring and body position channels to generate snoring level
and body position discrete states. The use of SBP/RESBP 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.
