Abstract

We planned a study to research the relations among blood pressure (BP), viscosity, and temperature in healthy subjects and among BP, viscosity, and glucose in diabetics. With simple random sampling method, 53 healthy and 29 diabetes mellitus (DM) type II subjects were selected. Parameters were determined with capillary viscometer and glucometer at 22°C, 36.5°C, and 39.5°C in healthy subjects, and at 22°C on diabetic patients during OGTT with 75 g of glucose. Statistical evaluations of the data were made with regression analysis, Student t test, Spearman’s correlation, and analysis of variance. When temperature decreased from 36.5°C to 22°C, blood viscosity increased %. This increase resulted in a % decrease in blood flow rate. According to the Hagen-Poiseuille equation, the required BP increase for compensation of the resulting tissue ischemia was %. Also, a % decrease in erythrocyte deformability and % increase in plasma viscosity were seen. When temperature increased from 36.5° to 39.5°C, blood viscosity decreased %. This caused % decrease in blood flow rate, and % decrease in BP, according to the equation. Erythrocyte deformability increase of 9.92% and plasma viscosity decrease of 4.99% arose from the temperature rise. There is a correlation between total data for temperatures and viscosities (r = ?0.84, P < .001). Continue Reading
