Equilibrio ácido base en el adulto mayor

Aging is a physiological process characterized by progressive deterioration of organ functions, where the ability to adapt and respond to a stressful situation is reduced. The alterations in the acid-base balance represent a milestone little understood in the elderly. Being associated with polypharmacy, the effects per se of advanced age in organs such as liver, lung and kidney are the cause of these alterations. A non-systematic review of literature was carried out through the PubMed database and the SciELO and SpringerLink portals. To integrate these review and analysis, we identified those scientific studies that proposed an explanation of renal and pulmonary changes associated with age and having an effect on acid-base homeostasis.
