Introduction
Indications for Use The MediByte® is a portable sleep data recorder used to record physiological signals during sleep while the patient is either at home or in a clinical environment. The data is downloaded after the recording is completed and the assist software enables the trained human professional - typically a Registered Sleep Technologist or Medical Doctor - to review and verify the results of the study and generate a report. Target Population: Children and adult patients who are screened during sleep disorder studies. Environment of Use: The majority of screenings occur either in the home or in a clinical setting. Caution: United States Federal law restricts this device to sale by or on the order of a physician.

Introduction
Overview of the MediByte Screener The MediByte® was designed for quick clinician-to-patient turnaround. The clinician prepares the unit for data collection using the MediByte® Software. After the clinician prepares the MediByte®, the patient sleeps with the device and returns it to the clinician for data download and analysis. The data download and data analysis are performed using the MediByte® Software. After reviewing the data, the clinician generates a report using the software.
Description of the MediByte Screener The MediByte® Screener is a compact ambulatory device designed to efficiently aid in the detection of a number of sleep disorders; such as apnea, upper airway resistance and snoring. Because of its small size and portability, clinicians are no longer limited to recording data in an artificial sleep environment. Data collection can occur in the patient’s natural surroundings, over a more extensive period than might otherwise be practical in a sleep lab. The MediByte® Screener records up to twelve channels of physiological signals, including: audio, flow, snoring (volume), snoring (audio), blood oxygen saturation (SpO2), pulse rate, chest effort, abdominal effort, body position, sum and CPAP pressure. The MediByte® Screener consists of the following major components: •
the MediByte® unit
•
the communication cable
•
BRAEBON sensors
•
MediByte Software.

Introduction
The MediByte Unit ®
The MediByte® unit has a plastic molded case with an Event button and Status LED on the front. On the top portion of the unit, there is an auxiliary (AUX) port for snoring volume or EKG/EMG sensors, a pressure port and an SpO2 port. On the bottom portion of the unit, there is a communication port, a chest effort port, an abdominal effort port and a collection on/off switch. See Figure 1.2 on page 1-9 for port locations. The Event button, located on the front of the unit, permits the patient to record an event by depressing the button. The event marker is defined by the clinician within the software. Common events are lights out, lights on and bathroom break.
Figure 1.1: MediByte
ON/OFF
The Status LED is a small light located on the front of the unit. It flashes green or red to indicate the current state of the unit. For example, the LED flashes green once every six seconds to show that the recorder is waiting to collect; and it flashes green twice every six seconds to show that the recorder is collecting. Continuous red blinking indicates that the battery is too low to record a study, although it may have enough charge remaining to download data. See Table 2-4 on page 2-4 for a complete list of Status LED indicators. The auxiliary (AUX) port, located on the top of the unit, attaches the snoring microphone; the lead wire yoke adapter which accepts EKG lead wires or EMG bruxism lead wires; or the PLM leadwire yoke adapter which accepts PLM lead wires. The cTherm thermistor cannula plugs into the white port located on the snoring microphone or either type of leadwire yoke adapter. The pressure port, located on the top of the unit, attaches the oral/nasal cannula to the recorder. You can also use this port to record CPAP pressure. The SpO2 port, located on the top of the unit, attaches the SpO2 sensor to the recorder. The communication port, located on the bottom of the unit, accepts the BRAEBON communication cable. Use this port to attach the recorder to the computer to configure a study and

Introduction to download the data from the recorder. Never attach the unit to the computer when it is already attached to the patient. The chest effort port attaches the chest effort (RIP) belt to the recorder. The abdominal effort port attaches the abdominal effort (RIP) belt to the recorder. The collection on/off switch sets the unit to record when in the manual mode. To start the recording, push the switch to the right (white dot). This switch only functions when the unit has been preset to manually record within the software. The collection on/off switch is disabled if the unit is preset to automatically record within the software. It is also disabled when the unit is connected to the computer.
For optimized performance and ease-of-use, BRAEBON recommends the automatic mode.

Communication Cable The communication cable connects the MediByte® to the computer. Use the communication cable to program the MediByte® for a study and for data download. A green LED on the communication cable displays when the MediByte® is properly connected to the computer.

Introduction
BRAEBON Sensors The MediByte® Screener uses the following BRAEBON sensors: •
Two respiratory effort belts (Model 8572). The respiratory effort belts, which plug into the chest and abdomen ports on the MediByte®, are used to aid in the diagnosis of sleep apnea.
•
One snore sensor (Model 8541). The snore sensor, which plugs into the AUX port on the MediByte®, detects snore sounds.
•
One optional leadwire yoke adapter (Model 8610). The leadwire yoke adapter, which plugs into the AUX port on the MediByte®, attaches electrodes to the MediByte®. Use this model for EKG studies.
•
One PLM leadwire yoke adapter (Model 8611). The PLM leadwire yoke adapter, which plugs into the AUX port on the MediByte®, attaches electrodes to the MediByte. Use this model for PLM and bruxism studies.
•
One SpO2 finger probe (Model 8897). The SpO2 finger probe, which plugs into the SpO2 port on the MediByte®, measures blood oxygen saturation and pulse. It is used to aid in the diagnosis of sleep apnea.
•
One oral/nasal cannula (Model 8597). The oral/nasal cannula, which plugs into the pressure port on the MediByte®, measures airflow. It is used to aid in the diagnosis of sleep apnea.
•
One cTherm cannula thermistor (Model 8514). The cTherm cannula, which plugs into the white input port on the snoring microphone or either type of leadwire yoke adapter, measures airflow with a thermistor. It is used to aid in the diagnosis of sleep apnea.
MediByte® Software MediByte® Software is the software designed to work exclusively with the MediByte®. The software has a handy configuration wizard to help you quickly configure the MediByte® for a study. All you need to do is enter the patient name, patient ID, patient weight and select the type of study you want to perform. The software sends this information to the recorder, telling it what types of channels are to be recorded and with whom to associate the data. After the patient has completed the study, download the data from the recorder onto the computer. The software will assist with data analysis. After you have reviewed the analysis and made any changes, you can enter more information into the Patient Info window and then generate and print a report.
