The husband of a patient who is critically ill asks, "Why do they keep checking my wife's pH? Isn't knowing her oxygen level enough?" What is the best response?
"As long as her oxygen levels are good, her pH really isn't that important."
"Many of her body's systems only work properly when her pH is within a narrow range, so we monitor it carefully."
"We want to make sure that she isn't running out of buffers to keep her pH just right."
"Yes, her oxygen levels are what's most important, but the lab always sends up all those numbers as a set."

Many of her body's systems only work properly when her pH is within a narrow range, so we monitor it carefully. In living organisms, maintaining a constant pH is crucial for optimal functioning, as chemical reactions rely on specific pH levels. The blood's pH balance is maintained by a buffer system involving carbonic acid and bicarbonate ions, essential for preventing pH fluctuations that could endanger survival.
