Summary
This document describes how to calculate the work that a person's respiratory muscles must do with and without the external breathing difficulties imposed by all types of RPD, except diving devices. This document describes the limits of additional hardship that people can tolerate and contains values that can be used to assess the acceptability of an APR. NOTE A few works dealing with respiratory physiology explain these calculations (in the absence of an APR), but most of them do not mention them or provide incomplete explanations.
