Breath-by-breath CO2 and O2 gas analysis
Online and offline analysis: respiration rate, peak flow, minimum flow, volume, compliance, and resistance
AcqKnowledge efficiently collects all data necessary for precise lung volume measurements and detailed respiratory airflow analysis for in lab and MRI applications. Investigate breathing mechanics by examining pressure/flow and pressure/volume relationships. Analyze respiratory gas consumption and production in real time and perform calculations for a complete metabolic analysis. All recorded data is clearly displayed in dedicated graph channels with breath-by-breath values and trends, and for X/Y plotting. Following data collection, use the powerful automated analysis tools to quickly extract advanced respiratory measures such as compliance and resistance, Penh analysis and pulmonary airflow.

Metabolic Analysis Script
This automated script, with the companion graph template, is used to measure metabolic parameters from a subject: air flow, CO2 & %CO2. This script requires an active AcqKnowledge Basic Scripting license and is available via download from BIOPAC (Script 052).
Use the bundled Automated Analysis tools to quickly obtain specific advanced Respiration measures. AcqKnowledge will score the waveform and export the results to a journal or spreadsheet file, or display them as new channels.

View AllThe Mobita 32-Channel EEG recording system was used in research examining if physiological data can be used to predict truly random events that correspond to perceptual stimuli. Baumgart, et al. from the University of California Santa Barbara utilized a quantum random number generator (qRNG) to choose from three randomized conditions: light, sound, and no stimulus. […]
BIOPAC provides software and hardware that allow for research teams to record and analyze respiration activity in physiological experimentation. Here are a few notable studies in monitoring respiration and cardiovascular activity. The coupling between peripheral microcirculation and slow breathing: The purpose of this study was to investigate the coupling of breathing movements and microcirculatory blood […]
