血气分析分型工具 · ABG Acid-Base Classifier

① 核心三项Core values

血气分析仪直接测得 pH 与 PaCO₂；HCO₃⁻ 实际上是仪器按 Henderson-Hasselbalch 公式反算得出的，并非直接测量值——这也是留空可自动计算的原因。 Blood gas analyzers directly measure pH and PaCO₂ by electrode. The reported HCO₃⁻ is actually back-calculated via the Henderson-Hasselbalch equation, not a direct measurement — which is why you can leave it blank and let this tool derive it.

pH *

PaCO₂ * mmHg

HCO₃⁻ mmol/L

病程 (用于判断呼吸性紊乱的代偿公式)Duration (affects the expected-compensation formula for respiratory disorders)

急性 (<12–24h)Acute (<12–24h) 慢性 (>3–5天)Chronic (>3–5d)

② 阴离子间隙参数Anion gap inputs (选填，强烈建议填写optional, strongly recommended)

用于识别高 AG / 正常 AG 代谢性酸中毒，并计算白蛋白校正 AG 与 Delta 比值，揭示被掩盖的混合性紊乱。 Used to distinguish high-AG from normal-AG metabolic acidosis, and to compute the albumin-corrected AG and delta ratio — which can reveal a masked mixed disorder.

Cl⁻ mmol/L

进阶：K⁺ / 剩余碱 / 生理化学(Stewart)视角Advanced: K⁺ / base excess / physicochemical (Stewart) view ▾

K⁺ mmol/L

实际碱剩余 BEBase excess (BE) mmol/L

K⁺ 用于计算"含钾阴离子间隙"(正常约10–20)；BE 仅作为与您常用方法的交叉核对，不参与主判断逻辑。 K⁺ enables a potassium-inclusive anion gap (normal ≈10–20); BE is shown only as a cross-check against your usual method and does not drive the primary classification.

③ 分型结果与推理链Classification & reasoning chain

填写左侧 pH 与 PaCO₂ 后点击"生成分型"，结果会显示在这里。 Enter pH and PaCO₂ on the left and tap "Classify" — results will appear here.

本工具基于波士顿法(Boston approach)代偿公式与 Winter's formula，仅用于辅助梳理判断思路，不能替代动脉血气报告解读的临床判断，极端值、机械通气参数骤变、慢阻肺基础值偏移等情况请结合临床。 Based on the Boston compensation rules and Winter's formula. This is a reasoning aid, not a substitute for clinical judgment — interpret with care in extreme values, acute ventilator changes, or a shifted COPD baseline.
