Even the mature clinician may have found that his understanding of the blood gases and their relationship to acid-base balance and to the manifestations of clinical disease has grown a bit rusty from disuse. For all these people, Ayers has provided a relatively painless way to review fundamentals by means of 42 slides illustrating partial pressure of gases, oxygen saturation, the oxygen paradox, alveolar ventilation, arterial and venous PCO2, acidosis, alkalosis, mixed syndromes or respiratory and metabolic acid-base disturbance, and the potassium balance.
