Abstract
The aim of this study was to analyze physiological changes, clinical and subjective symptoms by different $N_2O$ concentrations and administration method. This study surveyed 65 men and women ages 19 to 35 and all subjects were healthy volunteers, with no contraindication for use of $N_2O$ sedation. The $N_2O$ sedation was carried out in a way that increases by 10 percent to one-minute interval or increases at once the desired level. Each method was required to reach 30 or 50 percent $N_2O$ concentration. The way to gradually raise the $N_2O$ concentration can reduce the risk by decreasing the pulse reduction rate at the same $N_2O$ concentration. $SpO_2$ has no statistical significance according to $N_2O$ concentration and method of administration. Pulse rate reduced significantly when 50% $N_2O$ increase at once during sedation and 100% $O_2$ after 5 minutes. The way to gradually raise the $N_2O$ concentration is safe for reducing pulse rate.
