Abstract
A cost-effective instrument for the self-monitoring of peak expiratory flow (PEF) was used to map the time structure or chronome of this variable, with circadian to circadecennian rhythms. Self-measurements may detect changes in PEF associated with changes in personal health and/or air quality. For basic and applied purposes, a reduction in size of the measurement tool will be important until automatic instrumentation is developed.
