| Objective: We try to answer the question of “How much will (Co2) of blood change if we keep the amount of fresh gases constant” the subject of the present study on patients in Tajrish hospital in winter 1998. Methods: This research was done on 80 adults in the age group of 15-65, who were undergoing a surgical operation of lung. This was clinical trial using double blind sequential method subjects in control group were giner inspirations (12/min) and 12 times in the first 30 minutes for those in test group and in both groups the PaCo2 of blood was measured by the AVL system during the first 30 and 60 minutes. The amount of drug used before anesthesia and also the amount of anesthetic gases has been equal in both groups. Findings: The research outcome has shown that the amount of PaCo2 was not changed at all in control group where as it has increased among the experimental subjects from 28.74±3.38 in the first half hour to 34.32±3.65 in the first hour. While paired T test showed that this 20% increase can be noticeable, statistics (P<0.001) and the changes of PaCo2 in both groups also revealed to be clear and meaningful (P<0.001). Conclusion: The results have shown that increased respiratory rate increases the level of PaCo2, although such increments would be considered normal. |
