- portable peak flow meter
We therefore tested five portable peak flow meters of three types in an altitude chamber (sea level to 5,500 m) and in a climate chamber at sea level (7-37 degrees C) to determine the influence of :Customer reviews:Digital Peak Flow Meter This digital peak flow meter measuring peak flow and is very easy to use. Just turn it on and when you see go in the display, put your mouth over the mouthpiece and blow as fast and as hard as you can. Immediately thereafter it will display your peak flow in Liters/minute and FEV1 in Liters. Press the button again and you can repeat the process.
Sep 01, 1982 · The Armstrong units measure peak flow from 60-800 liters per minute (Lpm), while the Vitalograph scale ranges from 150 to 700 Lpm, though higher flows can also be recorded following the removal of two plastic plugs. The HealthScan instrument is, in effect, a rotameter, with air flow directed through a precisely-drilled orifice. Development of an accurate portable recording peak-flow Development of an accurate portable recording peak-flow meter for the diagnosis of asthma J Biomed Eng. 1993 May;15(3):188-92. doi:10.1016/0141-5425(93)90114-e.

Affiliation 1 School of Engineering, Staffordshire Peak Flow Meters - Medical Clinical Policy Bulletins AetnaA standard peak flow meter allows for simple measurements of peak expiratory flow. It consists of a spring-loaded pivoted vane which rotates inside a drum; a forced expiration through the inlet rotates the vane to an extent proportional to the maximum flow developed. The
May 01, 1994 · Little is known about the linearity of portable peak flow meters, or about physical gas factors affecting peak expiratory flow (PEF) readings. We therefore tested five portable peak flow meters of three types in an altitude chamber (sea level to 5,500 m) and in a climate chamber at sea level (7-37 degrees C) to determine the influence of the physical conditions of the gas on the reading of the :MABIS Portable Personal Peak Flow Meter for MABIS Portable Personal Peak Flow Meter for Asthma with Built-in Handle, 6 Zone Markers and Daily Record Chart, for Children and Adults, Blue Brand:Mabis. 4.3 out of 5 stars 12 ratings 3 answered questions Currently unavailable.
