Ultimately, why does a patient who is hyperventilating have difficulty breathing?

Question

Quizplus · Accepted Answer

Hyperventilation causes a decrease in carbon dioxide levels in the blood, which causes a respiratory alkalosis (increased pH) that reduces the urge to breathe. This results in a decrease in the depth and rate of breathing, leading to a feeling of breathlessness. The patient may also experience lightheadedness, tingling in the hands and feet, and muscle spasms. The body compensates for the alkalosis by decreasing blood flow to the brain, which leads to fainting if the hyperventilation continues. Therefore, the patient has difficulty breathing due to the lack of carbon dioxide, which impairs their ability to effectively inhale and exhale.
