PEFR may not be able to precisely identify GOLD stage, but earlier studies showed some efficacy of peak flow rate
measurements for daily monitoring in patients with COPD, COPD screening and initial identification of severe cases of COPD and then subsequently confirmed by spirometry.
The data, presented by Mark Rochester, M.D., consultant urological surgeon of Norfolk and Norwich University Hospitals NHS Foundation Trust U.K., demonstrates International Prostate Symptom Score, or IPSS, improvement for patients treated with the UroLift System in a real-world setting, as well as improved quality of life, or QoL, and peak flow rate
, or Qmax, at both the three and six-month follow up timepoints.
Detecting chronic obstructive pulmonary disease using peak flow rate
: Cross sectional survey.
To evaluate the flood peak dependence on the elongation ratio among basins of varying sizes, peak flow rate
in [m.sup.3] [s.sup.-1] was normalized by the drainage area to be converted to mm [h.sup.-1].
The pipeline system will be designed for a peak flow rate
of 7,500 barrels per hour (bph).
The normalized flow distribution factors for the standard fuel assemblies near the follower fuel assemblies are around 0.985, almost 4% lower than the peak flow rate
. The flow rates in the standard fuel assemblies vary by less than 3% from the average.
Lewis, "Expiratory peak flow rate
1: standard values for normal Subjects.
Cumulative volume versus time interval plots tend to start at a real time corresponding to a time of peak flow rate
. While not every time interval on a cumulative volume versus time interval plot follows an adjacent time interval in real time, it is approximately the case that the various increasing time intervals, especially at shorter time intervals, represent periods of peak flow rate
that on average are close to each other in real time, or could be, given day-today variations in flow rates.
3) Peak flow rate
. This is the fastest rate of air that you can blow out of your lungs.
• Has a peak flow rate
of 375 GPMs with gravels and 120 GPMs with heavy clays;
The peak flow rate
over a 24-hour period was approximately 100 barrels of oil per day.
