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

Hypopnea
The reduction range of respiratory airflow is more than 50% of the
normal, accompanied with more than 4% of oxyhemoglobin
saturation reduction.
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.
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).
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.
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.
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.
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.
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.
saturation reduction is more than 3% or 4% every hour.
CPAP
The CPAP means feeding continuous positive airflow into air
passage by face mask.
