Abstract:
We investigated the effects of hyper- and hypoventilation on gastric ([Formula: see text]) and sublingual (P[Formula: see text] ) tissue[Formula: see text] before, during, and after reversal of hemorrhagic shock. [Formula: see text] was measured with ion-sensitive field-effect transistor sensor and P[Formula: see text] with a CO 2 microelectrode. Under physiological conditions and during hemorrhagic shock, decreases in arterial ([Formula: see text]) and end-tidal ([Formula: see text] )[Formula: see text] induced by hyperventilation produced corresponding decreases in[Formula: see text] and P[Formula: see text]. Hypoventilation produced corresponding increases in[Formula: see text] ,[Formula: see text],[Formula: see text] , and P[Formula: see text]. Accordingly, acute decreases and increases in[Formula: see text] and[Formula: see text] produced statistically similar decreases and increases in[Formula: see text] and P[Formula: see text]. No significant changes in the tissue[Formula: see text] -[Formula: see text]gradients were observed during hemorrhagic shock in the absence or in the presence of hyper- or hypoventilation. Acute changes in[Formula: see text] and P[Formula: see text] should, therefore, be interpreted in relationship with concurrent changes in[Formula: see text] and/or[Formula: see text].
