Sunset Healthcare Solutions RES052 Pocketpeak

The Sunset Healthcare Solutions RES052 Pocketpeak is a mechanical, Class II medical device engineered for the objective assessment of Peak Expiratory Flow (PEF). Its primary technical advantage is its 'Universal Range' capability, spanning 50 to 720 L/min. This design choice allows the device to serve as a single-unit solution for both pediatric subjects and adult patients, eliminating the need for age-specific models. The device operates using a spring-loaded internal piston mechanism that captures the maximal expiratory velocity during a 'fast blast' maneuver. Clinical evaluation confirms that the RES052 adheres to standard performance requirements for domiciliary respiratory monitoring. The unit features an integrated, easy-to-grip handle to ensure proper hand positioning away from the airflow path, which is critical for measurement accuracy. The high-contrast numeric scale is supplemented by manually adjustable color-coded zone markers (Green, Yellow, Red), facilitating the easy implementation of asthma action plans. While it lacks the digital logging found in electronic monitors, its robust mechanical design and low unit cost make it a staple for large-scale clinical distribution and home-based self-management.
