Introduction This manual is intended for all users of the Embletta Gold Polygraphy (PG) system and applies to RemLogic-E™ and the Embletta Gold recording device. The manual includes information about performing sleep studies with the Embletta Gold, including how to attach the sensors to the patient, initialize the recording, and download the data in the acquisition application. The Embletta Gold is a 9-input, 14-channel polysomnographic recorder used to acquire patient physiological signals including respiratory, electroencephalogram (EEG), electrocardiogram (ECG, EKG), positional, user-triggered event, and oximetry, during sleep-related studies. The recorder allows for the storage of input channel data to an internal memory or a connected computer. When all 9 inputs are in use, the recorder permits a minimum of 24 recording hours. If the device is connected with a subset of these channels, the number of recording hours permitted will be greater. It is assumed that users have a basic knowledge of the Windows environment, working with a mouse, using toolbars, and arranging windows. Sections typically begin with an overview and description of main features, followed by instructions in simple action steps. For more information about any Embla product feature, or for technical support, please contact Embla Technical Support ([email protected]). The Embletta Gold is manufactured in the United Kingdom for Embla Systems.

Warnings, Cautions, and Certifications
Do not use the battery charger when the Embletta Gold is attached to the patient. The Embletta Gold may get warm during charging, and the battery charger cord may present a tripping hazard.
Do not use damaged sensors or accessories.
The conductive part of electrodes and their connectors, including the ground electrode, must not contact other conductive parts including earth.
If the single-use XactTrace® belts are not properly crimped, data may not be recorded. Crimping refers to the process of inserting the cut end of the belt into the catch of the Belt Lock and tightening until the white pin is partly covered.
The single-use XactTrace belt roll may contain junctions where belt parts are joined together with tape. Sections containing junctions should not be used for respiratory measurements. When cutting from the roll to make a belt for a patient, make sure there are no junctions in the belt.
XactTrace belts are intended to be worn over the patient's nightclothes.
As a result of the proliferation of radio-frequency transmitting equipment and other sources of electrical noise in health care and other environments, high levels of interference, due to close proximity or strength of the source, may disrupt the performance of the Embletta Gold. For these reasons, special precaution regarding EMC is needed when the device is installed and put into service.
While the Embletta Gold is recording, it is not advisable to use mobile phones, transmitters, and similar equipment that generate RF fields in close proximity to the device.
The isolated DC cable is required when recording signals from DC devices that are connected to AC power (mains power).
Do not connect DC devices that require AC mains power directly to the Embletta Gold.
The battery life of the Isolated DC cable is 40 hours. When the battery dies or is not present, the circuit stops functioning, and no signals will record. When the cable is not in use, move the on/off switch to the “off” position to conserve battery life.
Always inspect the equipment, particularly the cables and connectors, for evidence of wear before each study. If evidence of wear is found, remove the worn equipment from use and contact Embla Technical Support ([email protected]) for replacement or servicing.
Remove the batteries from the isolated DC cable if the product is not in use for an extended period of time.

Embletta Gold Clinical Manual | Page 15
Performing Studies Selecting the Study Type Preparing an Embletta Gold sleep study involves programming the Embletta Gold and attaching sensors to the patient. The Embletta Gold system assists in the collection of respiratory data along with one channel of LM, EKG, or EEG data. The Embletta Gold can be adapted to a variety of studies. Depending on the type of study selected, different sensors and additional interfaces are used. Below is a description of common study setups. See Working with Sensors for detailed instructions about the use of the sensors listed below and their placement on the patient. The Embletta Gold system offers two main study types: diagnostic and PAP.
Diagnostic Studies During diagnostic studies, data is collected to assist in identifying and diagnosing sleep disordered breathing. One channel of ExG can be recorded to detect PLM. This single channel can also be used to collect EKG or EEG data. The Embletta's sensor input area allows you collect data using a variety of sensors, including XactTrace respiratory effort sensors, an oximeter, a nasal cannula to measure flow and snore pressure, and a thermistor (optional).
PAP Studies PAP studies can be performed with a flow generator to measure the effectiveness of treatment, and to collect respiratory, position, and oxygen saturation information with the Embletta Gold. When performing a PAP study, instead of the nasal cannula, the pressure tube is connected from the luer lock to the PAP mask to record the mask pressure. In addition, a differential pressure sensor can be connected from the corresponding ports on the Embletta Gold to the differential pressure adaptor on the PAP hose. Differential pressure inputs allow the device to record more precise information about flow during the PAP study. The ResMed Therapy Device can also be used to measure the following ResMed Therapy Device signals: RMD Flow, RMD Pressure, RMD Leak, RMD Snore, and RMD Flattening. For more information, see Working with the ResMed Therapy Device.
Checking the Batteries The built-in rechargeable batteries provide a minimum recording duration of 8 hours when charged for 30 minutes from any battery state. To record 3 consecutive studies, charge the batteries for 2 hours and 15 minutes. Ensure the batteries are fully charged before connecting the Embletta Gold to the setup computer.
