Abstract

A study of the accuracy of the tpH electrode was performed in 10 cats. Hypoxia and acidosis were produced by ventilatory means and bicarbonate infusions were used to elevate the pH . Tissue pH correlated well with arterial (r = 0.9) within the physiological rates of change of pH. Prolonged tissue acidosis lead to eventual death. The correct and stable mechanical fixation of the pH electrode is a critical factor in assuring accurate results. The ROCHE tpH electrode accurately reflects arterial pH, and a correlation coefficient of at least 0.85 should be attainable in the human fetus.

摘要

对10只猫进行了tpH电极准确性的研究。通过通气方法造成缺氧和酸中毒，并使用碳酸氢盐输注来提高pH值。在pH值的生理变化率范围内，组织pH与动脉pH相关性良好（r = 0.9）。长期的组织酸中毒最终导致死亡。pH电极正确且稳定的机械固定是确保获得准确结果的关键因素。罗氏tpH电极能准确反映动脉pH值，在人类胎儿中应能获得至少0.85的相关系数。
