The article presents the results of space experiment “Pneumocard”. The investigation involved all 25 Russian members of the ISS crew. The total of 226 sessions were made including 130 aboard the ISS, 50 prior to launch and 46 on return from mission.
In order to evaluate the vegetative regulation of blood circulation and assess individual health risks under conditions of the 520 day isolation, used was an analysis of the heart rate variability (HRV). The most significant changes in the HRV values against the background data were reported in the second half of the said experiment.
Russian Academician Vasily V. Parin was one of the leading world scientists in the field of physiology of blood circulation. In this article his role in the development of the space cardiology, an important area of space medicine, is considered.
Research methodology and methods used in experiment Mars-500 held at the Institute of Biomedical Problems of the Russian Academy of Sciences in 2009-2011 are considered. 6 volunteers were isolated during 520 days in a sealed ground-based facility simulating space ship.
The paper presents the results of the long-term medical & ecological investigations conducted during the experiment Mars-500. Methodology of conducting the long-term medical & ecological investigations and the applied methods are considered.
The Sonocard experiment purpose was a noninvasive physiological signal recording from sleeping humans. In 2007-2012 the experiment was made by 22 Russian members of 17 missions to the International space station. Of the overall 302 experimental sessions 47 were performed pre, 215 in and 40 after flight.
Monitoring the health of astronauts based on the assessment of the functional state of the body within the realms of norm and pathology. The area of functional states qualifies as the yellow score of health on a notional scale "traffic light of health": Modern medicine is particularly interested in studying the health of the yellow score, because of the preventative measures that could still be taken before making contact with the healthcare system.
Experience of cosmonauts’ health monitoring shows that in the study of healthy subjects clinical approach to the evaluation of various medical and physiological data is almost less effective than the evaluation of organism adaptive abilities. The idea of prenosological diagnosis and the concept of adaptive risks develop in space medicine last years. These new space technologies are being actively tested in terrestrial studies in systems as "home medicine".
The detected phenomena of shunting of blood from large arterial trunks into large venous vessels is considered herein. The Cardiocode device is capable of detailed visual interpreting of a change or a significant reduction of a rheographic wave of the ascending aorta.
Consideration is being given herein to some mechanisms of high heart rate variability (high HRV), which cannot be attributed to sports exercise loading. The mechanism responsible for high HRV is explained as that resulted from the continuous performance (opening and closure) of arteriovenous anastomoses in different organs and systems in a human organism.
The paper is devoted to research and development of a new, based on Multiscale Correlation Analysis method of PVC (premature ventricular complexes) extra beats and SPB (supraventricular premature beats) online detection.
The article presents the main provisions of the methodology for the analysis of heart rate variability (HRV), which is now actively and widely implemented in many fields of medicine and applied physiology.
