The current paper talks about the biomedical monitoring system
and the technological advancements in them. Pulse oximetry
monitoring devices are used in general care units to record oxygen
saturation levels in the blood of the patient. Significant
postoperative complications are also monitored using oxygen
desaturation index of 4 percent. Certain physiological signals are
predicted by the monitoring techniques to understand the state of
the patient after the operation. This study has considered a
physiological signal to investigate the better model for predicting
the abnormal events that occur before any medical complication that
comes out after surgery.
Apart from several other models, the data-driven autoregressive
model was frequently used to build the dynamic models from the
physiological data. The authors mentioned that recently they have
developed AR-10 model to collect the signals regarding the dynamics
of oxygen desaturation levels and they seem to have used this model
to predict abnormal as well as critical oxygen desaturation
events.
The results section is explained by the authors that their AR-10
model did work well in predicting the signals regarding the
dynamics of oxygen desaturation levels. They have constructed a
dynamic model that could predict 20sec ahead of the abnormal event
and compared the results with that of the standard AR-10 model
anomaly. The rootmeansquareerror (RMSE) values computed for 20sec
ahead prediction were also compared with that of the standard AR-10
model.
Although the RMSE was found to be increasing in the proposed model
compared to that of the standard model, the proposed AR-10 model
was observed to have better ability to capture the abnormal events
of the oxygen desaturation of the patient's blood before any
complication. The AR-10 model prediction sensitivity was found to
have enhanced from 69.7% to 98.9%, which says that this model has
the higher capacity to predict the clinically relevant
events.
In conclusion, this paper talked about modeling and predicting the
dynamics of the blood oxygenation signals. A new performance
measurement technique has been used to identify the novel
predictive model of the oxygen desaturation signals by optimizing
the measurement.
