Description
Technical field
The present embodiments relate to sleep monitor technical field, more particularly to a kind of appraisal procedure and device.
Background technology
Think that the generation of low blood oxygen saturation event is related to OA and low pass gas event on modern medicine,
Can be to OSAHS (obstructive sleep apnea- by the Correct Analysis to the low blood oxygen saturation event order of severity
Hypopnea syndrome, obstruction sleep apnea-hypopnea syndrome) patient make more effectively judgement.
In prior embodiment, the assessment to the order of severity of oxygen desaturation degree event is mainly entered by following index
Row judges：
1) amplitude index
Amplitude index mainly comprising LSaO2 (lowest arterial oxygen saturation, during sleep most
Low arterial oxygen saturation) and mODD (mean oxyhemoglobin desaturation degree, it is flat during sleep
The fall of equal oxygen desaturation degree event).That is, the order of severity of the amplitude index in assessment oxygen desaturation degree event
When, standard is only estimated with numerical values recited or depth, depth is bigger, it is lower to be worth, oxygen desaturation degree thing then in sleep procedure
Part is more serious, sleep quality is poorer.
2) duration index：
By DCT (cumulative time percentages of oxyhemoglobin desaturation
During events, sleep the oxygen desaturation degree event cumulative time accounts for the percentage of total sleep time), i.e. oxygen desaturation degree event
Cumulative time and the ratio of total sleep time, assess the order of severity of oxygen desaturation degree event, and ratio is bigger, then in sleep procedure
Oxygen desaturation degree event is more serious, sleep quality is poorer.
3) frequency index：
By ODI (oxyhemoglobin desaturation index, oxygen desaturation degree thing in averagely sleeping per hour
The number of times of part), i.e. the frequency of the degree event of oxygen desaturation per hour weighs the order of severity of oxygen desaturation degree event, frequency
Higher, then oxygen desaturation degree event in sleep procedure is more serious, sleep quality is poorer.
The defect that prior art is present is as follows：
1) amplitude index and have ignored the duration of event to serious journey only for the depth of oxygen desaturation degree event
The influence of degree.
2) duration index and have ignored the amplitude of event to the order of severity only for the duration of oxygen desaturation degree event
Influence.
3) frequency index is only for whole sleep cycle, and cannot analyze the serious journey of single oxygen desaturation degree event
