Question

what are the physiological response of the body systems to the condition as it attempts to restore homeostasis in COPD patient?

(include all body systems involved)

Answer 1

The major physiological response of respiratory system is hyper capnea.

In the healthy patient, about 16,000–20,000?mmol/day of carbon dioxide (CO2), derived from oxidation of nutrients containing carbon, are produced. Under normal conditions, the production of CO2 is removed by pulmonary ventilation. However, an alteration in respiratory exchanges, as occurs in advanced phase of COPD, results in retention of CO2. Carbon dioxide is then hydrated with the formation of carbonic acid that subsequently dissociates with release of hydrogen ions (H+) in the body fluids. Thus, the consequence of hypercapnia due to alteration of gas exchange in COPD patients mainly consists in increase of H+concentration and development of respiratory acidosis, also called hypercapnic acidosis.

Also excessive fluid deficit leads to metabolic alkalosis in COPD patient.

Thus it maintaining an equilibrium in such Patients.
