The following points highlight the four main tests for determination of gastric function. The tests are: 1. Examination of Resting Contents 2. Fractional Gastric Analysis using Test Meals 3. Examination of Contents after Stimulation 4. Tubeless Gastric Analysis. Tests for Determining Gastric Function: Examination of Resting Contents Fractional Gastric Analysis using Test Meals Examination of Contents after Stimulation Tubeless Gastric [...]
In this article we will discuss about the Acid-base Balance and Acid-base Imbalance. Acid-base Balance in Normal Health: An acid may be defined as substance that produces H+ (protons) in solution, and a base is a particle that combines with hydrogen ions (H+). Example: Carbonic acid is an acid which is dissociated into H+ and HCO3− and its anionic component [...]
The upcoming discussion will update you about the difference between Metabolic Alkalosis and Respiratory Alkalosis. Difference # Metabolic Alkalosis: 1. HCO3- excess. 2. pH increased. 3. Disproportionate increase in [HCO3- ], [H2CO3], PCO2, pH. 4. Depression of respiratory centre and hyperventilation leading to retention of CO2. 5. In renal mechanism, there is increased NH3 formation and H+ - Na+ exchange, [...]
