Enter ventilation (VE) and oxygen uptake (VO2) at graded incremental loads to compute the VE/VO2 ventilatory equivalent, auto-detect the ventilatory threshold (VT) and assess the aerobic-anaerobic transition.
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Ventilatory equivalent | equivalent = ventilation / carbon dioxide output, normally under 30 | ATS/ACCP CPET statement |
| Slope method | regress ventilation on carbon dioxide output to gauge efficiency | ATS/ACCP CPET statement |
| Abnormal flag | a high slope flags reduced ventilatory efficiency needing clinical review | ATS/ACCP CPET statement |
通气比值分析工具,输入递增负荷测试中各强度的通气量(VE)与摄氧量(VO2),计算 VE/VO2 通气当量序列,自动识别通气阈(VT)拐点,帮助判定有氧—无氧过渡区间与有氧训练有效强度。
