Description
Technical field
The utility model relates to a kind of respiratory effort identification equipment and its sleep apnea monitoring devices of application, especially
It is related to the measurement for wing of nose action signal, respiratory effort is judged whether there is with wing of nose action signal.
Background technique
Sleep apnea syndrome becomes the research hotspot of medical field in recent years, according to " U.S.'s sleep medicine meeting
(AASM) interpretation standard ", sleep apnea event can be divided into obstructive type apnea, maincenter type apnea and mixed type and exhale
Inhale pause；When apnea occurs, there is the respiratory effort for continuing or enhancing during entire air-flow missing, then it is assumed that be
Obstructive type apnea；If respiratory effort is not present during entire respiratory air flow missing, then it is assumed that be maincenter type apnea；If
Breathe no more effort but event latter half respiratory effort of apnea start-up portion restores, then it is assumed that is that mixed type breathing is temporary
Stop.
The goldstandard of monitoring respiratory effort is to be tested by Esophageal Pressure, but Esophageal Pressure test is a kind of intrusive test,
Easily cause subject uncomfortable and is difficult to carry out whole night.Currently, the mode instead of Esophageal Pressure monitoring respiratory effort of extensive utilization is
Impedance caused by thorax abdomen respiratory movement or inductance variation are measured, such as breathing is carried out by chest and abdomen piezo strip or chest electrode piece and is exerted
The monitoring of power.
Currently, sleep analysis monitor (PSG) is the goldstandard for clinically diagnosing sleep apnea syndrome, it is most of
The monitoring still moved by chest and abdomen when PSG is tested is to determine whether there is respiratory effort, and PSG can be same in sleep whole night
When monitoring human body multi-channal physiological and more monitoring result parameter can be calculated.But in practical applications, lead sleep more
