C. B. McKerrow coauthored the 1959 primary report with Basil Martin Wright on maximum forced expiratory flow and a portable instrument for measuring it. The primary record retains the initials C. B.; no fuller name is established here. The scientific contribution links a compact flow measurement to quantitative assessment of ventilatory performance.^[ref]

Peak expiratory flow is the maximum of the expiratory volume-flow curve, whereas expired volume is its time integral:A maximum and an integral preserve different information. Their distinction motivates a flowmeter even when a volume measurement is also available.

For two original triangular flow pulses, let one have height 8 L/s and base duration 0.25 s, and the other height 4 L/s and duration 0.50 s. Both enclose 1 L, but their peak flows are 480 and 240 L/min. Equal expired volumes therefore do not imply equal peak flow. These stipulated traces are not human reference values or results assigned to McKerrow's experiment.

The surviving Wright instrument is documented by a primary museum collection record, including its portable construction and a dial graduated in litres per minute.^[ref] Such an instrument supplies a specific observable. It does not, from one peak alone, reconstruct the entire expiratory curve or distinguish every possible cause of an altered measurement.

J. Bartels is the first named author of the 1954 primary study comparing respiratory dead space measurements using single-breath analysis of oxygen, carbon dioxide, nitrogen or helium. The journal supplies the initial-only byline; it does not establish a fuller personal name. The measurement contribution concerns the relationship between expired gas composition and expired volume.^[ref]

A single expired breath is not compositionally uniform. Conducting-airway gas appears before gas from exchanging regions, with a transition that depends on mixing and measurement response. Pairing mouth-flow recording with gas-fraction recording allows elapsed time to be converted into an expired-volume coordinate. Synchronization matters because a gas analyser can respond later than the flow sensor.

An original idealized washout curve makes the volume interpretation concrete. Suppose a tracer fraction is zero over the first 100 mL, rises linearly to its plateau over the next 100 mL, and then stays at a plateau value $F_A$. The equivalent sharp-boundary volume under this flat-plateau model isThe transition contributes half its width. This synthetic equal-area construction explains a measurement principle; it is not a reported observation from Bartels's subjects.

A sloping plateau, incomplete tracer equilibration or analyser delay can change the inferred boundary. Comparing tracers therefore tests a physiological measurement model as well as an instrument. Bartels's verified authorship belongs to that gas-analysis experiment, without claiming that the initial-only name identifies a particular namesake or that every definition of respiratory dead space gives an identical volume.
