Introduction. In 2018, another update of the Clinical Practice Guidelines for the Prevention and Management of Pain, Agitation/ Sedation, Delirium, Immobilization and Sleep Disorders in Adult Patients Treated in Intensive Care Units (ICUs) was released. Aim. The study is aimed at presenting current recommendations concerning pain management in patients treated in ICU, and presenting the algorithm of pain assessment and monitoring in patients treated in ICU, using a Polish version of the BPS (Behavioural Pain Scale). The guidelines were prepared based on a systematic review of the literature published in the years 2013-2018. Material and methods. The search for scientific publications was carried out using electronic databases in English and Polish. The following keywords and their combinations were used in the searches: pain, assessment, monitoring, nurse, intensive care, adult patient, unable to communicate. Initially, 758 papers were identified with the use of keywords. After excluding duplicates and preliminary checking and selecting the titles of publications and abstracts, 85 papers were qualified for the analysis of full text. Conclusions. Access to effective pain treatment is a fundamental human right. Recommendations of the Polish Association of Anaesthesia and Intensive Care Nurses, concerning pain monitoring in ICU using a Polish version of the Behavioural Pain Scale (BPS), developed by the Task Force for Practice, are intended to provide a specific guideline for developing effective local pain management strategies in ICU.

“…Mathematically, the ratio of the standard deviation to the mean has another nomenclature in probability theory and statistics, namely the coefficient of variation (CV) which is also known as a relative standard deviation and a standardized measure of dispersion of a probability distribution or frequency distribution. CV was widely used in analytical chemistry to express the precision and repeatability of an assay [ 37 ], and in biology to assess pain or other something [ 38 ]. In addition, CV has been utilized by economists and investors in economic models and in determining the volatility of a security.…”

Railway axle bearings are one of the most important components used in vehicles and their failures probably result in unexpected accidents and economic losses. To realize a condition monitoring and fault diagnosis scheme of railway axle bearings, three dimensionless steadiness indexes in a time domain, a frequency domain, and a shape domain are respectively proposed to measure the steady states of bearing vibration signals. Firstly, vibration data collected from some designed experiments are pre-processed by using ensemble empirical mode decomposition (EEMD). Then, the coefficient of variation is introduced to construct two steady-state indexes from pre-processed vibration data in a time domain and a frequency domain, respectively. A shape function is used to construct a steady-state index in a shape domain. At last, to distinguish normal and abnormal bearing health states, some guideline thresholds are proposed. Further, to identify axle bearings with outer race defects, a pin roller defect, a cage defect, and coupling defects, the boundaries of all steadiness indexes are experimentally established. Experimental results showed that the proposed condition monitoring and fault diagnosis scheme is effective in identifying different bearing health conditions.
