In such cases, the pulmonary parenchyma ruptures and air enters both the pleural cavity and/or the lumen of ruptured blood vessels located in the alveolar septa. The result is permanent disruption of the pulmonary parenchyma. The aim of the study was to assess the influence of post-PB lesions on the heart muscle and the importance of hyperbaric treatment on the exacerbation of such lesions in the heart. The hearts of 35 rabbits were used in the study. In animals of the experimental group, PB was induced in the pressure chamber using the proprietary method described in previous publications. Part of the animals in this group were treated with air hyperbaria. The comparison group consisted of animals, which did not undergo PB during a simulated dive. All animals were weighed, observed for four weeks and then put to death following the experiment. In autopsy, among others, whole hearts were collected and weighed after fixation. Subsequently, the C/S ratio, i.e. the body to heart weight ratio, was calculated. The measurement results were subject to statistical analysis. A statistically significant increase in the C/S ratio was found, indicating an increase in the share of heart weight in the total body weight in the group of animals with PB not treated with air hyperbaria as compared to the control group.","PeriodicalId":40385,"journal":{"name":"Polish Hyperbaric Research","volume":"69 1","pages":"63 - 70"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49408032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article discusses the subject of validation of a selected measuring system for on-line control of the breathing gas production process and describes the application of multidimensional sensory systems to control critical parameters of the production process in production systems intended for intensive use away from supply facilities. In this case, the on-line contamination measurement option should be considered2. Monitoring of the analysed process from the point of view of its ability to minimise its variability should be oriented towards measuring the input or process values in such a way as to prevent the occurrence of potential defects already at the production stage. The assessment of the CCS - Carbon Dioxide Control System3 selected for testing, designed to control the carbon dioxide content, was performed in DUWT PNA4 for the DGKN - 120 complex compressed air supply system5. The system evaluation was conducted using MSA6 procedures and methods of SPC7.","PeriodicalId":40385,"journal":{"name":"Polish Hyperbaric Research","volume":"69 1","pages":"32 - 7"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45994145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Continuous electrocardiographic (ECG) Holter monitoring was conducted in a group of 50 divers (age 36,8 ± 8,7). The recorded data included the duration of the dive, including a period of 60 minutes before the dive and 60 minutes after the dive. Moreover, divers filled in a questionnaire that had been prepared for the purpose of the study and the psychological tests State-Trait Anxiety Inventory (STAI). The ECG recordings were synchronised with dive computers to correlate the ECG changes with diving events and analysed for the heart rate, arrhythmias and conduction disorders. The average heart rate was the highest (M=107.34 beats/minute) before diving, and the lowest after diving (M = 102.00 beats/minute). Supraventricular arrhythmias were recorded in nineteen (38%) of the participants of the study. The number of arrhythmias during diving (M = 14,45) is significantly higher than before (M = 9,93, p < 0,01) and after dive (M = 6,02, p < 0,05). All results were obtained from the continuous ECG Holter monitoring. It seems that using continuous ECG monitoring in conditions similar to diving (physical and psychological stress), brings more benefits than traditional, resting electrocardiogram.","PeriodicalId":40385,"journal":{"name":"Polish Hyperbaric Research","volume":"69 1","pages":"71 - 80"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45783429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To the model of professional underwater human activity underwater served the conditions of full saturation in compressed air or nitrogen-oxygen gas mixtures. Technical devices were presented by a number of underwater laboratories, mounted at the bottom (Ikhtiander-66, 67 and 68), hyperbaric chambers, submersible drilling rigs (Bur-1 and 2), and an autonomous diving Ikhtiander-2 for a long stay in the water. Studies of respiratory gases mass transport conditions in man showed than within the pressure range of 0.25-1.1 MPa at density of moderate hyperoxic and nitrogen-helio-oxygen environment up to 14 kg/m3 oxygen and carbon dioxide regimes of the organism come to a new functional level which provides the adaptation to the extremal conditions. It is determined that an increase of physiological dead breathing space, a decrease of the rate of the O2 diffusion through the alveole-capillary barrier, intensification of unevenness of ventilator-perfusional relations in lungs and an increase of blood shunting in lungs are the main respiratory mechanisms which regulate mass transfer of O2 and CO2 in man under hyperbaria. The leading hemodynamic mechanism is the retention of volume blood circulation and cardiac output. It is studied how the compression rate, high partial pressures of oxygen and nitrogen, microclimate parameters in inhabited hypebaric chambers influence changes of functional breathing system. Absence of hypoxic state is proved in man (full saturation of man with nitrogen) under normoxia in nitrogen-oxygen environment with the density 6.34 kg/m3. These are also the data about accelerated rehabilitation of divers using the method of active adaptation o high altitudes. Basic directions in physiological studies of functional breathing system under increased pressure of gas and water environment are described.","PeriodicalId":40385,"journal":{"name":"Polish Hyperbaric Research","volume":"68 1","pages":"118 - 93"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45862901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
