Peak expiratory flow at increased barometric pressure: comparison of peak flow meters and volumetric spirometer.
Increasing numbers of patients are receiving hyperbaric oxygen therapy as an intensive care treatment, some of whom have pre-existing airway obstruction. Spirometers are the ideal instruments for measuring airway obstruction, but peak flow meters are useful and versatile devices. The behaviour of both types of device was therefore studied in a hyperbaric unit under conditions of increased press...
متن کاملPrecision and accuracy of oxygen flow meters used at hospital settings.
BACKGROUND Oxygen therapy is an important therapeutic resource for patients with hypoxemia. When changing oxygen flow meters, we have observed that sometimes, even with the same oxygen flow setting as before, a different S(pO(2)) is obtained. OBJECTIVE To analyze the precision and accuracy of flow meters used in hospital settings. METHODS An experimental study was performed to test oxygen ...
متن کاملCompact Mass Flow Meter Based on a Micro Coriolis Flow Sensor
In this paper we demonstrate a compact ready-to-use micro Coriolis mass flow meter. The full scale flow is 1 g/h (for water at a pressure drop < 1 bar). It has a zero stability of 2 mg/h and an accuracy of 0.5% reading for both liquids and gases. The temperature drift between 10 and 50 °C is below 1 mg/h/°C. The meter is robust, has standard fluidic connections and can be read out by means of a...
متن کاملMicro Coriolis Mass Flow Sensor for Chemical Micropropulsion Systems
We have designed a micromachined micro Coriolis flow sensor for the measurement of hydrazine (N2H4, High Purity Grade) propellant flow in micro chemical propulsion systems [1]. The sensor measures mass flow up to 6 mg/s for a single thruster or up to 24 mg/s for four thrusters. The sensor will first be used for measurement and characterization of the micro thruster system in a simulated space v...
متن کاملA critical evaluation of thermal mass flow meters
Many semiconductor processes require that stable and known flows of gas be delivered to the processing chamber. The thermal mass flow meter ~TMFM! is used almost exclusively in the semiconductor industry for the admission of process gases. While TMFM’s have been used in the semiconductor industry for over twenty years, much still remains to be understood about their behavior. The abundance of T...
