ABSTRACT
<p><b>OBJECTIVE</b>To improve the method for monitoring sleep state and respiratory rhythm of SD rats, providing a solution for rats' chewing on the wires, signal loss and instability problems in the animal model of sleep apnea syndrome (SAS).</p><p><b>METHODS</b>We improved monitoring electrodes of both electrocorticogram (ECoG) and electromyogram (EMG), signal circuit and animal operation.</p><p><b>RESULTS</b>Operation time was shortened and wound exposure time was reduced, which made it easier for postoperative recovery. The ECoG and EMG signals were more stable with sharp image, and signal circuit lines had better conductivity and material durability, achieving continuous monitoring for a long time and high success rate. We could precisely distinguish the sleep wake state and the sleep apnea events in rats according to these signals.</p><p><b>CONCLUSION</b>The improved method is more reliable and practical to test the small animal model of SAS, and is more easily to operate and the signals are more stable.</p>
