Abstract:
Objective To compare the CT changes in lungs among mechanically-ventilated dogs before and after a single hyperbaric oxygen exposure,and investigate the effects of HBO on lungs.Methods Forty healthy adult dogs were randomly divided into 4 groups:the hyperbaric oxygen (HBO) group,the normabaric oxygen (NBO) group,the hyperbaric air group and the normabaric air group.All the dogs were mechanically ventilated and CT scan on lungs were taken before and after the session to compare the CT value by Picture Archiving and Communication System on different lung parts.Results There was no significant difference between all the groups of apical and median fields of lung CT values (P ＞ 0.05).In HBO and NBO groups,deficiency of pulmonary aeration developed preferentially in caudal lung fields.Compared with the NBO group,the changes of HBO group were more dramatic.There were significant differences in CT values between HBO and NBO groups(P ＜0.05).Conclusions Compared with NBO,ventilating at 0.2 MPa caused much more significant deficient aerations of the lungs.
