Diffusing Capacity and Barometric Pressure Adjusted for Altitude
Purpose: | To correct the diffusing capacity seen at high altitudes to that expected at sea level in order to adjust for the increase from the lower inspired oxygen pressure. |
Specialty: | Pulmonology |
Objective: | other testing, dosage calculations, exercise, travel |
ICD-10: | J40-J47, R94.2 |
Description: | Since the composition of inspired air is affected by altitude, the observed diffusing capacity seen at a certain altitude needs to be adjusted to sea level in order to allow accurate interpretation of the results. |
