In patients with respiratory compromise, it is important to look at the respiratory components of the blood gas to determine both oxygenation ability and adequacy of ventilation. To assess oxygenation, the partial pressure of arterial oxygen (PaO2) to fraction of inspired oxygen (FiO2) ratio, and alveolar-arterial gradient (A-a gradient) can be used. Conversely, the partial…
