The paper presents a solution for modeling the dynamics of human gas ex-change indicators in space flight based on a static model of the respiratory sys-tem, taking into account the peculiarities of gas exchange process. The paper also describes a computational experiment which was carried out to simulate indicators during ascent, demonstrating the capabilities of the model to predict the state of the respiratory system. The simulation results show that a decrease in the total barometric pressure leads to the respiratory capacity changes: the volume of the alveolar space decreases and the tidal dead space volume in-creases in the ratio from 4.7 to 0.7. A noncompensated respiratory alkalosis leading to the acid-base disorders develops as well. The computational experi-ment applied under the considered methodological approach allows studying the problems related to the flight safety and risk management under various operating modes of life support systems.

The article proposes a new methodological approach to understanding corruption threats to economic security on a national-state scale, based on the formation of a model for the system of strategic analysis, management and prevention of risks in the sphere of socio-economic development of the state. Underestimation of diagnostics and monitoring of recognition of corruption threats to national economic security in the context of an economic crisis may negatively affect the level of life support of citizens.

The article justifies the need for a theoretical and methodological approach to the study of the life support of rural residents as a system that takes into account social, economic, environmental and institutional specifics. A model of life support of the rural population characterizing the structure of its components is presented. A methodological approach has been proposed and a system of indicators has been defined linking the use of resources to meet the basic needs of rural residents and the quality of their lives. Rural areas of the region were typed according to the level of life support of the population, which allowed to identify the degree of their differentiation.

Mountain Sickness

Field studies of acute mountain sickness (AMS) usually include variations in exercise, diet, and environmental conditions over days and development of clinically apparent edemas. The purpose of this study was to clarify fluid status in persons developing AMS vs. those remaining without symptoms during simulated altitude with controlled fluid intake, diet, temperature, and without exercise. Ninety-nine exposures of 51 men and women to reduced barometric pressure (426 mmHg = 16,000 ft. = 4,880 m) were carried out for 8–12 h. AMS was evaluated by Lake Louise (LL) and AMS-C scores near the end of exposure. Serial measurements included fluid balance, electrolyte excretions, and plasma concentrations, regulating hormones, and free water clearance. Comparison between 16 subjects with the lowest AMS scores near the end of exposure (“non-AMS”: mean LL = 1.0, range = 0–2.5) and 16 others with the highest AMS scores (“AMS”: mean LL = 7.4, range = 5–11) demonstrated significant fluid retention in AMS beginning within the first 3 h, resulting from reduced urine flow. Plasma Na+ decreased significantly after 6 h, indicating dilution throughout the total body water. Excretion of Na+ and K+ trended downward with time in both groups, being lower in AMS after 6 h, and the urine Na+-to-K+ ratio was significantly higher for AMS after 6 h. Renal compensation for respiratory alkalosis, plasma renin activity, aldosterone, and atrial natriuretic peptide were not different between groups, with the latter tending to rise and aldosterone falling with time of exposure. Antidiuretic hormone fell in non-AMS and rose in AMS within 90 min of exposure and continued to rise in AMS, closely associated with severity of symptoms and fluid retention.

The Impact

Preparedness and complete alertness is one of the important elements of activities in reducing the risk and the impact of disaster. The same is true to nurses’ preparedness and complete alertness in providing emergency service in respiratory system which is urgently needed during the disaster immediate responsiveness. Quick and accurate service can help and save victims from physical defect and death Goal: The objective of the research was to know the condition of nurses’ preparedness and complete alertness in providing emergency service in respiratory system, based on the their knowledge, attitude, and skills. Methods: The research method is The research used a descriptive qualitative survey. The population was all 40 nurses who were involved in disaster response team in four Puskesmas working areas of the Health Office in Aceh Tamiang District: Kejuruan Muda Puskesmas, Karang Baru Puskesmas, Kota Kuala Simpang Puskesmas, and Bandar Pusaka Puskemas Result : The result of the research showed that 65% of the respondents had good knowledge, 82.5% of them had positive attitude, 55.0% of them were skillful in conducting the acting procedure of Heimlich maneuver, , and skillful in Lung-Heart Restitution was less Conclusion: The conclusion and the important implication in this research could that the education and the training of Basic Life Support and Basic Traumatic Coronary Life Support highly supported nurses’ alertness in providing emergency service in respiratory system.
