“…Entropy consists of two parameters, namely SE, which reflects the degree of hypnosis in the patient, and RE, which reflects the electromyographic response of the facial muscles to noxious stimulation [17]. Both parameters can distinguish between the awake and unconscious states [18]. In the present study, escalating doses of aminophylline both significantly increased the entropy values and shortened the recovery times.…”

“…This concept presents the advantages of multi-resolution analysis and complexity evaluation for timevarying signals, which means that the macro and micro aspects of some special signals could be researched in the time-frequency domain [48]. For this reason, wavelet entropy has gradually been adopted for a great variety of applications in medicine, machinery vibration detection, and system fault diagnosis [35,36,40,41]. The wavelet packet component signal f i j (t) can be expressed by a linear combination of wavelet packet functions ψ i j,k (t) as follows…”

“…These computations are useful clinically in patients under anaesthesia 16,17 ; or unable to communicate distress as in sleep apnea 18 or dyspnea [19][20][21] and the potential risk associated with diabetes mellitus 14 and obesity 15 has been studied previously using these methods. This study aimed to assess the risk of dynamical disease by novel chaotic globals to HRV in subjects with malnutrition.…”
