The Analysis and Design of a Pressure - Measuring Syringe Utilizing
Endotracheal tube insertion requires the measurement of very low pressure. Currently, there exists no reliable method or device that is integral with the inflation syringe for measuring this pressure. Thus, a device for quickly and easily reading the pressure was created within the syringe currently used to pressurize the tube. This device takes the form of elastomeric bellows. These bellows we...
متن کاملSafety of pressure-volume curve measurement in acute lung injury and ARDS using a syringe technique.
STUDY OBJECTIVES To assess the safety of frequent pressure-volume (PV) curve measurement in patients with acute lung injury (ALI)/ARDS. DESIGN Prospective observational study. SETTING Academic medical-surgical critical care unit. PATIENTS Consecutive patients with ALI or ARDS. INTERVENTIONS Static inspiratory PV curves of the respiratory system were determined twice on day 1, then once ...
متن کاملCalibration of pneumotachographs using a calibrated syringe.
Pneumotachograph require frequent calibration. Constant-flow methods allow polynomial calibration curves to be derived but are time consuming. The iterative syringe stroke technique is moderately efficient but results in discontinuous conductance arrays. This study investigated the derivation of first-, second-, and third-order polynomial calibration curves from 6 to 50 strokes of a calibration...
متن کاملDesign and Analysis of Pressure Vessel Subjected to Pressure-temperature Variation (TECHNICAL NOTE)
Pressure vessel is a container used to store fluids under pressure and temperature. The fluids can be air, water, chemicals, fuel, gases etc. are most commonly used in food and chemical industries, oil refineries and so on. Pressure vessel is subjected to thermal and structural loads for power plant applications. Since the pressure vessel are subjected to both structural and thermal loads stres...
متن کاملLow-cost feedback-controlled syringe pressure pumps for microfluidics applications
Microfluidics are widely used in research ranging from bioengineering and biomedical disciplines to chemistry and nanotechnology. As such, there are a large number of options for the devices used to drive and control flow through microfluidic channels. Commercially available syringe pumps are probably the most commonly used instruments for this purpose, but are relatively high-cost and have inh...
