6. Glossary
Snore Because of the respiratory tract’s airway limitation, sound is made
when respiratory airflow gets through the narrow respiratory tract,
which usually indicates that the patient is likely to have suffered in
years from sleep apnea syndrome along with the increase of age.
Apnea The performance of respiratory intermission during sleep is that the
respiratory airflow drops to lower than 10% of the normal range and
lasts for at least 10 seconds. The recurrent intermission during
sleep is easy to cause severe oxygen-deficit to brain and blood,
form hypoxemia and induce hypertension, brain-heart disease,
arrhythmia, myocardial infarction and angina, which then can induce
multi-system diseases of the human body.
Hypopnea The reduction range of respiratory airflow is more than 50% of the
normal, accompanied with more than 4% of oxyhemoglobin
saturation reduction.
SAHS The SAHS means at least 30 times of apnea in 7 hours of nightly
sleep time of adults and each apnea lasts for more than 10 seconds.
Or the apnea hypopnea index AHI (the number of apneas and
hypopneas per hour) is greater than 5.
OASHS The OSAHS means the sleep apnea hypopnea syndrome caused by
obstruction of the upper respiratory tract (including the collapse of
pharyngeal mucosa).
AI The AI means the number of apneas per hour, which is equal to the
number of times apnea has occurred the whole night divided by the
sleep time of whole night (awakening and invalid time are not
contained). The unit of time is hour.
HI The HI means the number of hypopneas per hour, which is equal to
the number of times hypopnea has occurred the whole night divided
by the sleep time of whole night (awakening and invalid time are not
contained). The unit of time is hour.
AHI The AHI means the number of apneas and hypopneas per hour
which is equal to the total times of apneas and hypopneas during
the whole night divided by the sleep time of whole night (awakening
and invalid time are not contained),and the unit of time is hour.
SNI The SNI means the average number of times the snore has occurred
every hour which is equal to the number of times snore has occurred
the whole night divided by the sleep time of whole night (awakening
and invalid time are not contained). The unit of time is hour.
ODI The ODI means the number of times when the oxyhemoglobin
saturation reduction is more than 3% or 4% every hour.
CPAP The CPAP means feeding continuous positive airflow into air
passage by face mask.

9. System Features
9.1 General Introduction
The performance and functional characteristics of YH-600B Pro include all the user-friendly features of
the predicate device.
YH-600B Pro is powered by one 1.5 V AA battery. Testing was performed to demonstrate that the
performance of YH-600B Pro in its intended environment is as safe and effective as that of the legally
marketed predicate devices. The safety and effectiveness of YH-600B Pro have been verified through
performance-related testing that consisted of Electrical Safety, Electromagnetic Compatibility,
Mechanical and Environment Testing.
The recorded data, such as SpO2, pulse rate, airflow waveform, snore and CPAP pressure, can be
replayed on a computer via the PolyLogic Sleep Analysis Software which is provided with YH-600B Pro.
The device can be used as a standalone unit for recording data. It can also interact with a commercially
available IEC60950-1 compliant computer, which can be used to review data. The device does not have
any audible alarms, and, therefore, should not be used for continuous monitoring.

Note:
①
The pulse oximeter equipment is calibrated to display functional oxygen saturation.
②
The sampling rate of the SpO2 signal is about 50 Hz, and the update rate of the frame is 1 Hz. So
even there are some filtering methods to process the SpO2 data, it will not delay for a relative long
time to the displaying data.
③
The waveform of the signal is non-normalized so that the software can provide to the operator
that the pulse rate value displayed is potentially incorrect. However, YH-600B Pro which does not
store the waveform data just keeps waveform updating to give the implication of the detector in
working state.
④
If the pulse oximeter sensor is in an abnormal state, the value of SpO2 will be blank.
⑤
The value of SpO2 and PR is calculated by the average of the former eight pulse waveforms.
