effect of pH on the oxygen equilibria of the different hemoglobins varied greatly, from Root effect to reverse Bohr effect, the effect of CO2 on the oxygen affinity was very similar for all but that of the catfish, Brachyplatystoma sp., for which the effect was somewhat larger.4.The ...

Hyperventilation will ___ (increase / decrease / have little effect on) the pH of blood plasma. (Hint: Think about what effect hyperventilation will have have on PCO2 in the alveoli and therefor on the blood and then think about...

Inhaling high concentrations of CO2suppresses the removal of metabolic waste CO2. The increase in CO2metabolic waste results in high arterial PaCO2(hypercapnia), decreasing blood pH (acidosis; pH < 7.2)22. Since acid–base and PaCO2balance are important for survival, mammals possess mechanisms...

1co2气腹对呼吸系统的影响co2对呼吸系统的影响主要表现在肺通气、血ph值、paco2等方面。co2气腹使腹腔内压力增加,膈肌上抬,气道压力上升,胸腔内压力升高,呼吸系统顺应性下降,呼吸潮气量及肺泡通气量减少,继而影响肺通气功能。leighton等1研究表明膈肌每上抬1cm,肺的通气量减少300ml。体位变化可引起膈肌运动改变,影响...
