Abstract:
Effect of carbon dioxide bath on cardiovascular functions and peripheral circulation were studied using a new system of carbon dioxide bath. The subjects consisted of 13 males and 17 females, ranging from 50 to 84 years old, 67.4±8.3 in average, having the complaints resulting mainly from arteriosclerosis such as coldness on extremities or exertional pains of lower extremities. Each subject took a bath in plain water (PW) on the first experimental day and then a bath in carbon dioxide (CO2) at the same time on the second experimental day. Both baths were done for 10min. at 39°C of water temperature. The results obtained were as follows.
1) Mean blood pressure (MBP) was elevating during bath and lowered below prebath level immediately after bath in both PW and CO2 groups. However, MBP in CO2 group was lower significantly (p<0.05) than in PW group 20 and 30min after bath.
2) Both body and skin temperatures were similarly elevated at all points to be measured directly after bath, and then lowerd gradually thereafter. There was no significance in changes between both groups.
4) An increase in cutaneous blood flow was observed at the same grade in both groups during and after bath, though no showing significant difference between both groups.
5) PO2 in venous blood increased after bath, while PCO2 decreased. However, no significant difference in these changes was observed between both groups.
6) Tendency to increase in CV R-R was observed during and after bath, though no significant difference was showed between both groups.
7) Relating to the feeling to bath, all subjects had the feeling of “warmness” at the beginning of bath and also of comfortableness during and after bath in both PW and CO2 groups. However, there was no difference in the intensity of these feelings between both groups.
8) No side reaction due to an inhalation of carbon dioxide during bath was observed in all subjects.
From these results, it is expected that a new carbon dioxide bath results in benefit for patients with disturbance of peripheral circulation.
