Respiratory Acidosis

Respiratory acidosis can arise from a break in any one of these links. For example, it can be caused from depression of the respiratory center through drugs or metabolic disease, or from limitations in chest wall expansion due to neuromuscular disorders or trauma (Table 90-1). It can also arise from pulmonary disease, card iog en ic pu lmon a ryedema, a spira tion of a foreign body or vomitus, pneumothorax and pleural space disease, or through mechanical hypoventilation. Unless there is a superimposed or secondary metabolic acidosis, the plasma anion gap will usually be normal in respiratory acidosis. Introduction Respiratory acidosis is characterized by an increased arterial blood PCO2 and H+ ion concentration. The major cause of respiratory acidosis is alveolar hypoventilation. The expected physiologic response is an increased PHCO3. The increase in concentration of bicarbonate ions (HCO3) in plasma (PHCO3) is tiny in patients with acute respiratory acidosis, but is much larger in patients with chronic respiratory acidosis. Respiratory alkalosis is caused by hyperventilation and is characterized by a low arterial blood PCO2 and H+ ion concentration. The expected physiologic respo Continue reading >>

    Can I do keto and still eat fruits?

    I know fruits have carbs but the keto diet has really grown on me and helped me shed body fat. But I really can't live without fruits and vegetables. Do I have to let go of fruits completely from the keto diet? Or can I still have them even if it makes it a low-carb diet?
