摘　　要：观察HFTJV和HFJV对用琥珀胆碱阻断了自主呼吸的狗在开胸前、后的通气效率。结果:开胸前,两者通气时的PaO_2均比自主呼吸时高(P<0.05),而PaCO_2均比自主呼吸时低(P<0.01),但HFYJV时PaCO_2水平低于HFJV时(P<0.01),PH高于HFJV时(P<0.05);左胸开放后与开胸前比较,PaO_2降低(P<0.01),但PaCO_2差异不显著,且HFTJV时的PaCO_2和PH水平亦与HFJV时无明显差异。作者对上述血气变化的机制和两种喷射通气的通气效率提出了见解。The ventilation eficiency of HFTJV and HFJV in dogs with apnea induced by succinylcholini chloridum was observed before and after opening the chest. The result showed: Before opening the chest, PaO_2 was higher (P<0.05)and PaCO_2 lower (P<0.01 ) both during HFTJV and HFJV than those during spontaneous respiration, and the level of PaCO_2 was lower (P<0. 01 )and PH was higher (P<0. 05)during HFTJV than those during HFJV. After opening the left chest, as compared to before that, PaO_2 decreased (P<0. 01), but no significant change was found in PaCO_2. There was no fignificant difference in levels of PaCO_2 and PH between HFTJV and HFJV. The mechanism of the above blood-gas changes and ventilation efficiency of the two kinds of jet ventilation have been discussed.
