Maximal respiratory pressure reference values for Navajo children ages 6-14

Background Since anthropometric variables are critical to the creation of pulmonary nomograms for FVC, FEV1, and other volumes and capacities, it is logical that anthropometric variables also influence the values of the maximal respiratory pressures (MRPs). Since nomograms are race-specific, it is important that tribe-specific tables of normal maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) be developed. To date normal tables for MRPs do not exist for Navajo children. Objective Therefore the purpose of this study was to derive MRP normative reference values for Navajo children in the age range of 6–14 years. Methods—Participants and Measurements A cross-sectional st…
