Arterial blood-gas interpretations in the respiratory intensive-care unit
Abstract:
The role of the nurse in the respiratory intensive-care unit requires increased sophistication as our knowledge of the patient becomes more complex. This expanded role should include a thorough understanding of disturbances in acid-base balance, the relationship of PaCO2 to ventilation, the difference in acute and chronic respiratory problems, and the causes and treatment of hypoxemia. The ability to analyze and evaluate blood-gas determinations is simply one more important tool the nurse may utilize in the care and treatment of the critically ill patient.

The Role of Diffusion in Respiration
Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. In the respiratory system, this principle...
Diagnosing Acidosis and Alkalosis
First, the pH level is assessed to determine whether the blood pH is normal (7.35–7.45), low (acidosis), or high (alkalosis).
Next, the PCO2 and HCO3− values are examined to...
