Respiration Physiology
|May 1, 1979
Summary
This study developed a synthetic model to understand mammalian blood acid-base properties across temperatures. The model integrates various factors, improving predictions for blood acid-base status under different conditions.
Area of Science:
- Physiological chemistry
- Biophysics
Background:
- Existing models for blood acid-base balance often simplify temperature effects or use different compartment analyses.
- Reconciling these approaches is crucial for a comprehensive understanding of blood physiology.
Purpose of the Study:
- To develop a synthetic physicochemical model for oxygenated mammalian blood acid-base properties.
- To integrate constant and variable temperature effects into a unified model.
- To reconcile single-compartment and dual-compartment analyses of blood acid-base behavior.
Main Methods:
- Compiled literature data on blood constituents and buffer constants.
- Developed a physicochemical model simulating steady-state distribution of CO2, electrolytes, and water between plasma and red cells.
- Incorporated experimental values into a set of governing equations.
Main Results:
- The model successfully predicted blood acid-base relationships and quantities not initially included.
- Demonstrated good agreement between model predictions and experimental data.
- Validated the model's ability to simulate acid-base transformations.
Conclusions:
- The synthetic model provides a robust framework for analyzing mammalian blood acid-base properties.
- Highlights the importance of considering temperature and blood composition variations.
- Challenges current assumptions in blood acid-base state presentations that neglect these variables.

01:20Compartment Models: Two-Compartment Model
The two-compartment model divides the body into central and peripheral compartments to account for varying blood perfusion rates among organs and tissues, affecting drug distribution. The central compartment includes blood and highly perfused tissues with rapid drug distribution, while the peripheral compartment contains tissues with slower drug distribution. After a single IV bolus dose, the drug concentration is high in plasma and low in tissues. The drug distribution between compartments...
01:25Acid-Base Balance
The human body maintains a narrow pH range regulated through acid-base balance. This balance is crucial as changes in the hydrogen ion concentration can disrupt cell membrane stability, alter protein structures, and change enzyme activities. The normal pH of arterial blood is 7.4, venous blood and interstitial fluid is 7.35, and intracellular fluid averages 7.0.
When the pH of arterial blood rises above 7.45, it results in a condition called alkalosis. Conversely, a drop below 7.35 leads to...

01:18Respiratory Regulation of Acid-Base Balance
Respiratory compensation is a vital physiological process that stabilizes blood plasma pH by regulating the partial pressure of carbon dioxide (PCO2), a key determinant of pH levels. Most carbon dioxide in the blood dissolves and converts into carbonic acid (H2CO3). It dissociates into hydrogen ions (H+) and bicarbonate ions (HCO3⁻). There is also an inverse relationship between PCO2 and pH.
When carbon dioxide levels increase in the blood, more H+ and HCO3⁻ are produced, leading to a...

01:05Two-Compartment Open Model: Overview
Multicompartmental models are crucial tools in pharmacokinetics, providing a framework to understand how drugs move within the body. The two-compartment model is a crucial subtype, segmenting the body into central and peripheral compartments. The central compartment represents areas with high blood flow, such as plasma and highly perfused organs like the kidneys and liver, while the peripheral compartment signifies tissues with lower blood flow, like adipose tissue and muscle tissue.

01:15Two-Compartment Open Model: IV Infusion
A two-compartment model is a vital tool in pharmacokinetics, providing an essential understanding of drug behavior, especially for those administered via zero-order intravenous infusion. This model outlines two compartments: the central compartment, where elimination occurs, and the peripheral compartment.
The model illustrates the decrease in plasma drug concentration from the central compartment with a specific equation. It shows that under steady-state conditions, the drug's input rate...

01:06Three-Compartment Open Model
The three-compartment open model is a pharmacokinetic model used to describe the distribution and elimination of drugs following extravascular administration. It comprises a central compartment representing the plasma and two peripheral compartments. The highly perfused peripheral compartment represents organs and tissues with a rich blood supply, such as the liver, kidneys, and lungs. The scarcely perfused peripheral compartment represents tissues with lower blood supply, such as adipose...
