ABG interpretation uses pH, PaCO2, and HCO3 to diagnose acid-base disturbances. It's essential for critical care management.
Пошаговое руководство
- 1Check pH: <7.35 acidemia, >7.45 alkalemia
- 2Identify primary problem from PaCO2 and HCO3
- 3Assess appropriate respiratory compensation for metabolic disorders
Решённые примеры
Ввод
pH 7.25, PaCO2 55, HCO3 24
Результат
Primary respiratory acidosis with metabolic compensation inadequate
Requires ventilatory support
Распространённые ошибки
- ✕Assuming PaCO2 direction matches pH (opposite for respiratory)
- ✕Neglecting appropriate compensation rules
Часто задаваемые вопросы
What's the A-a gradient used for?
Assessing lung oxygenation function; elevated gap indicates intrinsic lung disease.
How do you know if compensation is appropriate?
Use Winter's formula for metabolic acidosis or expected PaCO2 formulas for metabolic alkalosis.
