Root Cause

Normal respiratory rates vary by age: infants 30-60, toddlers 24-40, school-age 18-30, adults 12-20; applying adult thresholds (e.g., >20) to a 2-year-old fails to detect tachypnea (typically >40) indicating pneumonia or distress.

正常呼吸频率因年龄而异：婴儿30-60，幼儿24-40，学龄儿童18-30，成人12-20；将成人阈值（如>20）应用于2岁儿童无法检测到呼吸急促（通常>40），提示肺炎或窘迫。

Workarounds

  1. 95% success Use age-specific RR reference table: `python -c "t={'0-1mo':[30,60],'1-12mo':[24,40],'1-3yr':[24,40],'3-6yr':[22,34],'6-12yr':[18,30],'12+yr':[12,20]}; age='2yr'; print(f'RR range: {t["1-3yr"]}')"`

Dead Ends

Common approaches that don't work:

  1. 95% fail

    Infants normally breathe 30-60; threshold >20 misses tachypnea; conversely, >40 in adults is extreme but normal in infants

  2. 80% fail

    This overestimates upper limit for young children (e.g., 24 for 2-year-old vs actual 40) and underestimates for infants

  3. 85% fail

    Tachypnea can precede desaturation; early detection of increased work of breathing is critical for intervention
