Three-Zone Management for Structured Asthma Monitoring
The PF120A features a built-in adjustable three-zone indicator system ? green (good), yellow (caution), and red (danger) ? that can be set to each patient’s personal best reading. This colour-coded zoning approach aligns directly with standard asthma action plan protocols, enabling patients and clinicians to make consistent, objective decisions about medication and escalation without interpretation ambiguity. Easy-to-read graduated numbers across the 60?800 L/min scale ensure accurate reading at a glance, even during respiratory distress.
EN ISO 23747:2009 Compliant with Accuracy Assurance
The PF120A is manufactured to EN ISO 23747:2009 ? the international standard governing the performance requirements for peak expiratory flow meters ? and carries CE approval. Compliance with this standard confirms accuracy and repeatability across the full measurement range, providing clinicians with confidence in serial measurements used to monitor asthma severity, assess bronchodilator response, and identify early deterioration before symptoms become severe.
Washable and Compatible with Disposable Mouthpieces
The PF120A body is washable for infection control and accepts disposable mouthpieces, making it suitable for individual patient use and multi-patient clinical settings. Its compact, lightweight form factor requires no batteries or electronic components ? eliminating device failure due to power, making it reliable in any care environment including home use, outpatient clinics, emergency departments, and occupational health screening. Storage is rated for 10?C?35?C at 30?75% relative humidity.
