WebJul 18, 2024 · A buffer is a solution which consists of a weak acid and its conjugate base, that can resist a change in pH when a stronger acid or base is added. B u f f e r + H + ⇔ H. B u f f e r. Buffering: Is a key part of acid-base homeostasis. Allows compensation for large changes in acid or alkali load with minimal change in hydrogen ion concentration. WebPulmonary shunt. A pulmonary shunt is the passage of deoxygenated blood from the right side of the heart to the left without participation in gas exchange in the pulmonary …

WebAlveolar Gas Equation. The alveolar gas equation is a formula used to approximate the partial pressure of oxygen in the alveolus (PAO2):PAO2= (PB−PH2O)FiO2− (PaCO2÷R)where PB is the barometric pressure, PH2O is the water vapor pressure (usually 47mmHg), FiO2 is the fractional concentration of inspired oxygen, and R is the gas … WebCollapse Lt Lung – processes contributing to hypoxia – V/Q, shunt, PVR, Pulse oximetry: VIVA 2009 A 07: Patient with PE.
