3. General Warnings and Cautions
3.1. Warnings
Portable RF communications equipment (including peripherals such as
antenna cables and external antennas) should be used no closer than 30
cm (12 inches) to any part of the Wesper Lab Patches, including cables
specified by WESPER. Otherwise, the performance of this equipment
could be negatively impacted.
3.2. Cautions
Do not expose the Patches to direct heat or flammable products.
Do not immerse or expose the Patches to water or other liquids.
The Patches are intended for use on adult patients.
Do not use the Patches if they show any sign of damage.
Replace the device if it is not working properly.
Use of the Patches in any way other than that described in this manual is
prohibited.
Do not fully immerse the Patches into alcohol or solvents.
Do not allow the Patches to get wet.
Expired or damaged Patches are to be discarded according to electronic
waste disposal regulations in your region.
Use of Wesper Lab Patches adjacent to or stacked with other monitoring
equipment should be avoided as the presence of other equipment could
result in improper operation. If such use is necessary, the Wesper Lab
Patches and the other equipment should be observed to verify that they
are operating normally.

Use of accessories, transducers, and cables other than those specified or
provided by WESPER could result in increased electromagnetic emissions
or decreased electromagnetic immunity of Wesper Lab Patches and result
in improper operation.
Do not use the Patches if outside the appropriate temperature range, as
specified in Section 7.1.1 Environmental and Storage Conditions.
Do not use the Patches if the casing is damaged.
Do not use the Patches if the lights on the Patch do not light up during
initial pairing.
Do not use the Patches if the lights on the Patch do not change color
during initial pairing.
Do not use the Patches if there is no measurement indication.
Use only authorized pulse oximeters, a list of which can be found at
www.Wesper.co/oximeter.

4. Conditions for Use
4.1. Indications for Use
The Wesper Lab is a digital recording device designed to be used under the
direction of a physician or trained technician but may be applied by a
layperson. Wesper Lab records multiple physiological parameters from a
sleeping patient for the purpose of simultaneous or subsequent display of the
parameters. The displayed data assists in the identification of sleep apnea by
trained personnel. Wesper Lab is intended to be used for adult sleep studies
at home or clinical environment. The device does not monitor or diagnose the
patient and does not issue any alarms.
4.2. Contraindications
Use of this device is contraindicated for pediatric patients, including infants
and neonates.

5. System Overview
5.1. Why WESPER?
Wesper Lab is a digital recording device designed to collect sleep data in adult
patients as prescribed by a healthcare professional.
Wesper Lab uses a set of comfortable adhesive Patches to record physiological
parameters during sleep. The kit is coupled with a compatible pulse oximeter
to collect information about pulse rate and oxygen desaturations. This
information is wirelessly transmitted and stored using the Wesper mobile
application. The data is then forwarded to the WESPER Cloud for use by the
care provider.
Wesper Lab is simple to use. An adhesive layer is used to attach the Patches to
the patient’s skin, and the App is configured to record data in a few simple
steps. The collected data is delivered to the patient’s healthcare provider who
can analyze the information as they normally would for any physiological
recording device.
5.2. WESPER in Brief
Wesper Lab uses an FDA-cleared pulse oximeter and a proprietary set of
flexible, thin, wireless, and wearable adhesive Patches designed to record
sleep disorder data in adult patients.
The Patches consist of a battery-powered physiological recording system
encapsulated in layers of fabric (top layer), silicone (bottom layer), and
medical-grade skin adhesive. The adhesive is safe for adult patient use. It is
strong enough to keep the Patches affixed to the body throughout a single
night.
The Patches collect multiple physiological parameters related to sleep quality,
including sleep position and respiratory effort. The pulse oximeter records
oxygen saturation levels and pulse rate. Data from the Patches and the pulse
oximeter is transmitted via low-energy Bluetooth (BLE) throughout the night
to a companion mobile application installed on the patient’s personal mobile
device. The data is then uploaded to a secure cloud-based server after the
recording has ended.
Clinicians can access this data for interpretation and use it as additional
information to support diagnoses of sleep apnea.
