This document provides errata for chapters in a spirometry certification book. It makes corrections to a table noting the right main bronchus is wider than the left, changes a figure label from FVC to VC, replaces a figure with two new figures on interpreting spirometry results using fixed cut-off values and lower limit normal values, and removes two subfigures.

1. BASIC LUNG FUNCTION TESTS, SECOND EDITION, 2019
FOR MTS SPIROMETRY CERTIFICATION
ERRATUM, MAY 2022
CHAPTER 1:
Table 1
Bronchus * The right main bronchus is more wider and shorter compared to the
left main bronchus (erratum)
They subsequently divide into secondary and tertiary bronchi, bronchioles
and terminal bronchioles. (Figure 5)
CHAPTER 3:
Figure 2: Spirogram; lung volumes and capacities
Change FVC to VC
CHAPTER 7:
Replace Figure 5 with this two figures.
Addendum- Figure (i): Spirometry results interpretation with fixed cut-of values
(Predicted values).

2. Addendum- Figure (ii): Spirometry results interpretation with Lower Limit Normal values (LLN).
