      "description": "计算肺泡-动脉氧分压差（A-a gradient）以鉴别低氧血症原因。肺泡气方程：PAO₂ = FiO₂ × (P_atm − 47) − PaCO₂ / 0.8（RQ 呼吸商默认 0.8）；A-a = PAO₂ − PaO₂。正常 A-a ≈ (年龄 + 10) / 4（室内空气，青年 <15 mmHg，每 10 年增约 3 mmHg）。正常 A-a 提示低通气或高海拔（PaCO₂ 常升高）；升高提示 V/Q 失衡（肺炎/哮喘/COPD/PE/肺水肿）、分流（ARDS/肝肺综合征/右向左心内分流）、弥散障碍（间质性肺病）或混合静脉氧低。P_atm 默认 760 mmHg 可按海拔调整。来源 StatPearls NBK545153、LITFL、Cornell PICU。不构成医疗建议。",
