VO2 peak
Pronunciation: V-O-two peak
The highest rate of oxygen consumption achieved during maximal exercise testing in cardiac patients.
Full Definition
VO2 peak represents the maximum oxygen uptake capacity measured during incremental exercise testing in cardiac rehabilitation patients. Unlike VO2 max in healthy individuals, VO2 peak acknowledges that cardiac patients may not achieve true maximal oxygen consumption due to cardiovascular limitations, medications, or early test termination. This measurement is critical for exercise prescription and assessing functional improvement throughout the rehabilitation program.
Usage
Usage note: Always use 'peak' rather than 'max' when referring to cardiac patients to reflect potential cardiovascular limitations.
In Context
- "The patient's VO2 peak improved from 12 ml/kg/min to 18 ml/kg/min following the 12-week cardiac rehabilitation program." — Progress assessment report
- "Exercise intensity was prescribed at 60-70% of the patient's measured VO2 peak." — Exercise prescription documentation
