我们研究了失血性休克逆转之前、期间和之后过度通气和通气不足对胃（）和舌下（P）组织的影响。用离子敏感场效应晶体管传感器和CO2微电极测量P。在生理条件下和失血性休克期间，过度换气引起的动脉（）和潮气末（）的降低导致相应的、和P的降低。换气不足导致相应的、、和P的增加。因此，急性减少和增加在统计学上产生了类似的减少和增加在和P。没有显着变化的组织-在失血性休克期间，在不存在或存在换气过度或换气不足的情况下观察到梯度。因此，和P的急性变化应与和/或的同时变化联系起来解释。
We investigated the effects of hyper- and hypoventilation on gastric () and sublingual (P) tissuebefore, during, and after reversal of hemorrhagic shock.was measured with ion-sensitive field-effect transistor sensor and Pwith a CO2microelectrode. Under physiological conditions and during hemorrhagic shock, decreases in arterial () and end-tidal ()induced by hyperventilation produced corresponding decreases inand P. Hypoventilation produced corresponding increases in,,, and P. Accordingly, acute decreases and increases inandproduced statistically similar decreases and increases inand P. No significant changes in the tissue-gradients were observed during hemorrhagic shock in the absence or in the presence of hyper- or hypoventilation. Acute changes inand Pshould, therefore, be interpreted in relationship with concurrent changes inand/or.
