WebSep 7, 2024 · A normal A–a gradient for a young adult non-smoker breathing air, is between 5–10 mmHg. Normally, the A–a gradient increases with age. For every decade a person has lived, their A–a gradient is expected to increase by 1 mmHg. A conservative estimate of normal A–a gradient is less than [age in years/4] + 4. Thus, a 40-year-old should ... Web0.21. This is the fraction of oxygen considered in natural air as 21%. Patient age. This is used to determine a conservative estimate of a normal A-a gradient based on the following formula: (Age + 4) / 4. The alveolar – arterial gradient formula is: A-a gradient = [FiO2 (Patm – PH20) – PaCO2 /0.8] – PaO2.
