Periodic checks of peak flow meter (PFM) stability is essential to ensure meaningful application even when the PFMs are only used to measure the relative changes in patient peak flow rate. Calibration of PFMs becomes necessary, however, when peak flow readings are to be interpreted precisely. Techniques and flow systems which offer ease and accuracy in calibrating and/or checking PFMs were tested on Standard Wright and Mini-Wright PFMs. Individual Wright PFMs were found to be stable over a six-month testing period. The PFM readings varied from actual flow, however, and the variation from actual flow was greatest among the Mini-Wright PFMs.
即使峰值流量计（PFM）仅用于测量患者峰值流速的相对变化，定期检查其稳定性对于确保有意义的应用也是必不可少的。然而，当需要精确解读峰值流量读数时，PFM的校准就变得必要了。在标准赖特（Wright）和迷你赖特PFM上测试了在校准和/或检查PFM时兼具简便性和准确性的技术及流量系统。发现单个赖特PFM在为期六个月的测试期内是稳定的。然而，PFM的读数与实际流量存在差异，且在迷你赖特PFM中，与实际流量的差异最大。
