Respiratory Gas Analysis

Respiratory Gas Analysis

Respiratory Gas Analysis is the study of the mixture of gases being inspired or expired by an animal or human subject. The primary gases of interest are typically oxygen and carbon dioxide. The changes in this gas mixture between inhalation and exhalation, combined with a measurement of respiratory flow, can be used to estimate metabolic rate.

Respiratory Gas Analysis

Signal Overview

Gas exchange occurs via simple diffusion in unicellular organisms. However, complex multicellular organisms require a respiratory system for effective gas exchange, which is integrated with the circulatory system to carry gases to and from the tissues. In humans, this system consists of the airways, the lungs, and the respiratory muscles that control the movement of air in and out of the body.
Respiration serves as a means for the body to exchange gases with the atmosphere via blood. Each inhalation transports clean oxygenated air into the lungs, where molecules of oxygen diffuse into the blood. Carbon dioxide molecules simultaneously diffuse from the blood and are transported out of the lungs during exhalation.

All your Respiratory Gas Analysis analysis in one place

LabChart software is designed specifically for life science data and provides up to 32 channels for data display and analysis options that are powerful and easy to use. With auto-recognition of ADI and LabChart Compatible hardware, multi-window views, one touch recording, simultaneous recording from multiple devices, specialized preconfigured settings, easy sharing options and an interface that can be customized to show only the features you want to use.

Adjusting flow rate in respiratory gas analysis

ADInstruments’ Gas Analyzer allows the flow rate of gas being drawn into the instrument to be adjusted. For human studies this flow rate should be set at maximum (200ml/min) to ensure the fastest possible response time. For studies on small animals the flow rate can be decreased to work with the much smaller gas volumes.
