base imbalences. Vomiting and diarrhea may also cause acid base imbalance.The kidneys are an essential buffer system for acids and in the older adults the kidneys are less able to compensate for an acid load. The older adult also has decreased respiratory function leading to impaired compensation for acid base imbalences. In addition tissue hypoxia from any cause may alter acid base balance. The must always consider the possibility of acid base imbalence in patients with serious illnesses. pH and

These conditions are not rare or uncommon in clinical practice‚ but everyday occurrences on the ward or in critical care. Conditions such as asthma‚ chronic

Acid-Base Balance and Fluids and Electrolytes Student’s Name Institutional Affiliation Date Due Respiratory Acidosis Respiratory acidosis refers to a medical defect in which hypoventilation occurs leading to increased concentration of carbon dioxide in the blood and decreased level of pH. Decreased pH in the blood is generally known as acidosis. The body cells continuously respire and release carbon dioxide. The lungs may fail to efficiently expel the CO2. This condition is known as alveolar

arterial line. The ABG analysis is mainly used to evaluate gas exchange in the lungs. It is also used to assess integrity of the ventilatory control system and to determine the acid-bas level of the blood. The ABG analysis is also used for monitoring respiratory therapy (again by evaluating the gas exchange in the lungs). Nursing considerations: Your first look at an ABG result might prove to be confusing. Any patient who is critically ill might be given this test at regular intervals. Arterial blood gas
