Hypercapnic

The approach to adult patients with suspected hypercapnia, as well as the diagnosis and treatment of acute hypercapnic respiratory failure are discussed in this topic. For the most part, this topic discusses the approach in patients who are spontaneously breathing, although many of the same principles can be applied to patients who are receiving invasive or noninvasive ventilatory support. The mechanisms, etiologies, and end-organ effects associated with hypercapnia are discussed more extensively separately. The presenting features of acute hypercapnia are variable with no signs or symptoms that are sensitive or specific for the diagnosis. Patients can present with the manifestations of hypercapnia itself as well as with the manifestations associated with the underlying disorder, both of which are discussed in detail in the sections below. It is important to remember that tachypnea does not always equate to increased alveolar ventilation; patients with increased dead space and mechanical abnormalities of the respiratory system may have elevated respiratory rate and accessory muscle use, yet still be hypercapnic.

Hypercapnia, also known as hypercarbia, is a condition that occurs when a person has too much carbon dioxide CO 2 in their bloodstream. It can cause dizziness, fatigue, and shortness of breath. In mild hypercapnia, the body can often regulate itself, temporarily altering breathing by gasping or taking deeper breaths. Chronic cases, however, usually require medical intervention. Consistently increased levels of CO 2 in the bloodstream can be harmful over time, increasing the pH of your blood and affecting the health of the lungs, respiratory system , and other major systems in the body.

Hypercapnia is the increase in partial pressure of carbon dioxide PaCO 2 above 45 mm Hg. Carbon dioxide is a metabolic product of the many cellular processes within the body, and there are several physiological mechanisms that the body has to moderate carbon dioxide levels. These include the acid-base buffering system that involves a balance between bicarbonate and carbon dioxide. Consequently, hypercapnia leads to acid-base imbalance. This activity describes the evaluation, diagnosis, and management of hypercapnia and stresses the role of team-based interprofessional care for affected patients.

Two large series can guide the impact of hypercapnia on mortality. Normal respiration in divers results in alveolar hypoventilation resulting in inadequate CO 2 elimination or hypercapnia. On the other hand, restoring normocapnia after sustained hypocapnia can result in normocapnic acidosis due to relative bicarbonate deficiency due to no compensation at the renal level [ 35 ]. Effect of a protective-ventilation strategy on mortality in the acute respiratory distress syndrome. Hypercapnia happens when breathing problems make it difficult to take in oxygen and breathe out carbon dioxide.
