Abstract Introduction: Sleep breathing disorders occur in 45% of patients with heart failure, with 36%-50% manifesting Cheyne-Stokes respiration with central sleep apnea and 12% exhibiting obstructive sleep apnea. Several studies have shown that sleep pathophysiology may negatively affect the cardiovascular system and that cardiac dysfunction alters sleep and respiration. Objective: The aim of this study was to examine oxyhemoglobin desaturation during sleep in patients with congestive heart failure (CHF) using overnight pulse oximetry. Methods: Overnight pulse oximetry was conducted in the patients' homes with wrist pulse oximeters and finger probes that were placed around the forefingers of 15 patients with CHF and ejection fractions less than 50%, who were classified as New York Heart Association functional classes II and III. Results: The patients were divided into two groups. The first group consisted of seven patients with oxyhemoglobin desaturation indices of over 5 events/h, and the second group contained eight patients with oxyhemoglobin desaturation indices of 5 or less events/h. Student's t-tests did not show any significant differences between the groups. The patients' body mass indices correlated positively with the total desaturation episodes and desaturation time less than 90% and correlated negatively with the arterial oxygen saturation nadir. Conclusion: Pulse oximetry monitoring during sleep can be used to detect sleep breathing disorders in stable patients with CHF.

Safety Monitoring System

Coal mine is important and basic industries in the country, and it is very important to establish a sound, reliable coal mine safety monitoring system for the safety production of coal mine. The demand analysis was made for the development of coal mine safety monitoring system. It contains to build up the layout model of the standard coal mine underground production environment and set all kinds of underground transducers especially methane transducer. On this basis, the general design scheme of coal mine safety monitoring system was determined. Demand analysis and scheme design provided for coal mine safety monitoring system can meet the needs of practical application and establish the foundation for the subsequent system development.

Abstract Background: It is not well-known if diagnosing and treating sleep breathing disorders among individuals with idiopathic pulmonary fibrosis (IPF) improves health outcomes. We evaluated the association between receipt of laboratory-based polysomnography (which is the first step in the diagnosis and treatment of sleep breathing disorders in Ontario, Canada) and respiratory-related hospitalization and all-cause mortality among individuals with IPF.Methods: We used a retrospective, population-based, cohort study design, analyzing health administrative data from Ontario, Canada, from 2007-2019. Individuals with IPF were identified using an algorithm based on health administrative codes previously developed by IPF experts. Propensity score matching was used to account for potential differences in 41 relevant covariates between individuals that underwent polysomnography (exposed) and individuals that did not undergo polysomnography (controls), in order minimize potential confounding. Respiratory-related hospitalization and all-cause mortality were evaluated up to 12 months after the index date. Results: Out of 5044 individuals with IPF identified, 201 (4.0%) received polysomnography, and 189 (94.0%) were matched to an equal number of controls. Compared to controls, exposed individuals had significantly reduced rates of respiratory-related hospitalization (hazard ratio [HR] 0.43, 95% confidence interval [CI] 0.24-0.75), p=0.003) and all-cause mortality (HR 0.49, 95% CI 0.30-0.80), p=0.004). Significantly reduced rate of respiratory-related hospitalization (but not all-cause mortality) was also observed among those with >=1 respiratory-related hospitalization (HR 0.38, 95% CI 0.15-0.99) and systemic corticosteroid receipt (HR 0.37, 95% CI 0.19-0.94) in the year prior to the index date, which reflect sicker subgroups of persons. Conclusions: Undergoing polysomnography was associated with significantly improved clinically-important health outcomes among individuals with IPF, highlighting the potential importance of incorporating this testing in IPF disease management.

Introduction. Sleep disorders in children with nervous system pathology are more pronounced than in the general population. One of the most common causes of sleep disorders in children is sleep-disordered breathing. The aim of our study was to create an algorithm for the diagnosis of sleep breathing disorders in children with neurological pathology. Materials and methods. The results of night studies (160 polysomnographies, 98 cardiorespiratory monitorings) carried out in the department of instrumental diagnostics at the National Medical Research Center for Children’s Health in 258 children (154 boys and 104 girls, aged one month to 17 years) with neurological pathology were analyzed. Questionnaires were used to assess the quality of sleep. An essential criterion for dividing children into groups was the presence of maxillofacial anomalies (MFA). The results were compared with complaints according to questionnaires, age, BMI and ENT-status of patients. Results. In the general sample, a significant (p < 0.001) relationship between respiratory disorders and complaints and the presence of ENT pathology was obtained. The most severe breathing disorders were recorded in children with MFA (p < 0.001). The result was the creation of an algorithm for examining children with neurological pathology. Conclusion. Children with neurological pathology in sleep-breathing disorders require a personalized approach to correcting the causes of these disturbances, depending on the nosology. Chronic pathology of the ENT organs aggravates respiratory disorders during sleep. Regular monitoring of sleep disorders using questionnaires should be included in the algorithm for managing children with neurological diseases of all ages for early detection of these disorders.
