Abstract
Acid–base homeostasis of the body requires the lungs, kidneys, and a complex system of buffers. The maintenance of a normal pH of 7.35–7.45 of arterial blood is ideal for optimal organ function. This chapter will describe the role of the lungs, kidneys, and complex buffers in acid–base balance. The chapter will review the diagnosis, sources, and treatment of metabolic and respiratory acidosis and alkalosis. Mixed disorders and compensatory mechanisms will be discussed in this text. The chapter will conclude with the influence of nutrition on acid–base balance (Roberts 2013; Ayers and Dixon 2012; Madias 2002).
