Anxiety respiratory alkalosis

Respiratory alkalosis is the rise in pH associated with excessive respiration. Hyperventilation, which can result from anxiety or high fever, is a common cause. The body may control blood pH during hyperventilation by fainting, which results in slower respiration. An intervention that may prevent fainting is to have a hyperventilating person breathe into a paper bag, which allows much of the respired CX)2 to be taken up again. [Pg.573]

Respiratory alkalosis is characterized by an increased arterial pH, a primary decrease in the arterial PaC02 and, when present for sufficient time, a compensatory fall in the HCOf concentration. Respiratory alkalosis represents hyperventilation and is remarkably common. The most common etiologies of respiratory acidosis are listed in Table 25-7 and range from benign (anxiety) to life-threatening (pulmonary embolism). Some causes of hyperventilation and respiratory acidosis are remarkably common (hypoxemia or anemia). [Pg.428]

This client is in respiratory alkalosis, which is caused by hyperventilating and could be the result of anxiety, elevated temperature, or pain. The nurse should assess the cause and administer the appropriate medication. [Pg.99]

Respiratory alkalosis is caused by hyperventilating—breathing rapidly and deeply. Hysteria, anxiety, or prolonged crying may result in hyperventilation in which too much carbon dioxide is exhaled, which disturbs the blood s normal carbon dioxide/carbonic acid ratio. According to Le Chatelier s principle, Reaction 15.6 (written again below) shifts to the right as it attempts to restore the equilibrium ... [Pg.485]

Respiratory alkalosis is associated with many illnesses. Hyperventilation has several causes. The CNS respiratory centre is stimulated by many factors including anxiety, psychosis, pain and fever. Overdosage of salicylates can initially stimulate ventilation causing respiratory alkalosis which may be followed by metabolic acidosis. Stimulation of the chest receptors by conditions such as pneumothorax, pulmonary embolism and pulmonary oedema can cause hyperventilation and hypocapnia. Other causes include mechanical ventilation, hepatic failure and sepsis... [Pg.18]

Any situation that causes an increase in respiration can result in respiratory alkalosis if the situation persists long enough. Anxiety, if extreme, can cause hyperventilation and loss of CO. Low oxygen levels in the blood (i.e., hypoxemia), such as is caused by lung disease or high altitudes (which have lower oxygen levels in the air), can stimulate a patient to breathe faster. [Pg.173]

Formally, alkalosis is a significant increase in the pH of extracellrdar fluid.ii Both respiratory alkalosis and metabohc alkalosis are known. Respiratory alkalosis results from h5q)erventilation, which produces lowered Pco2 and higher pH of extracellular fluids.ii Anxiety is the usual cause of hyperventilation. Metabohc alkalosis can result from the loss of gastric juices that are rich in HCl fi um excessive sodium bicarbonate ingestion, and it is associated with potassium ion deficiency. ... [Pg.38]
