Özet
Objective: The aim of the study is to investigate the relationships between temperature, blood viscosity and blood flow rate, heart rate, blood pressure and pulse pressure by using temperature stress of cooling and warming on the blood circulatory system. Material and Methods: The volunteer and healthy 36 cases were selected using the Simple Random Sampling Method. The study group remained in a cooled room (15 degrees C) for one hour and then were allowed to warm up with an electric blanked (100-watt) in the next period of one-hour. At the end of these two periods, temperatures of arm, leg and axilla, blood pressures, heart rates and blood viscosities of the subjects were measured immediately. Results: The results showed that there were clinically and statistically important relationships among blood pressure, heart rate, blood viscosity and pulse pressures during temperature stress of cooling and warming (p=0.001). However, the pulse pressures of healthy individuals remained constant despite temperature stress related systolic and diastolic pressures changed at rest position, which may resulted from circulatory compensation. Conclusion: The system analysis of the data and relationship between the parameters provided explanations for mechanisms of cold angina, tachycardia of fever, heat shock, hypertension and circulatory burden based on temperature stress and blood viscosity.
