Peak Expiratory Flow
Also written as PEF.
| Peak expiratory flow (PEF) diary | Is there diurnal variability indicating uncontrolled disease? | >20 % variation between morning and evening readings over 2 weeks → characteristic of asthma |
What our notes say
- | Peak expiratory flow (PEF) diary | Is there diurnal variability indicating uncontrolled disease? | >20 % variation between morning and evening readings over 2 weeks → characteristic of asthma | (Asthma)
- Peak expiratory flow: diurnal variability above 20% over 2 weeks; low early morning "dips". (Asthma)
- Peak expiratory flow monitoring (diurnal variation above 20%). (Internal Medicine Respiratory CAT 1: 30 MCQs and 5 short answer questions)
- | Peak expiratory flow | Severity of large airway obstruction | <50% predicted/personal best shows severe attack | (Approach to respiratory symptoms and the chest examination)
- Serial Assessment: Continually reassess respiratory rate, work of breathing, pulse oximetry, and repeat peak expiratory flow rate (PEFR) post-bronchodilator. (Approach to respiratory symptoms and the chest examination)
- Monitor peak expiratory flow, oxygen saturation, arterial blood gases (Medical MCQs: Chemical Pathology & Haematology Exam Review)
