Quality
The instrument's ability to reproduce a measurement.
What is precision?
A device for measuring flows and volume changes.
What is spirometer?
The most accurate when gas flow is laminar but turbulent flows can affect the accuracy of the measurement.
What is Fleish pneumotachograph?
Operates on the principal of thermal conductivity using Wheatstone bridge.
What is an electrical analyzer?
Shared device used to measure the CO2 with 10 to 12 patients.
What is mass spectrometer?
Regular and accurate calibrations is performed
What is daily or before each testing session?
What is flow-sensing devices?
Estimated airflow projected by pulsed sound waves along the flowmeter.
What is a Non-vortex ultrasonic flowmeter?
The presence of gases other than oxygen and nitrogen?
What is erroneous results?
Portable devices used for single patient use to measure the concentration of CO2 at the airway opening.
What is Infrared (IR) and Raman spectroscopy?
The volume tolerance limits for an acceptable calibration.
What is + or - 3%
Testing speeds of 32, 160 and 1920
What is a Collins (Water-Sealed) Spirometer?
A bi-directional flow-measuring devices that uses a flexible obstruction for measuring flow.
What is a variable pneumotachograph?
Analyzers that are used for intermittent or continuous monitoring of FIO2 or flammable gases during anesthesia.
What are electrochemical analyzer?
What is the galvanic and polargraphic analyzer?
A sampling device that are not good with high respiratory rates and is prone to getting clogged.
What is side stream (IR) spectroscopy?
Linearity, frequency response, sensitivity to environmental conditions and calibrations.
What is accuracy?
Measurement of flows between 3-300L/min
What is a turbine flowmeter?
A series of fine-mesh stainless steel screen to create a resistance.
What is a screen pneumotachograph?
It consists of 3 electrodes: sensing, counter and reference immersed in a electrolyte solution that contains a highly conductive acid or alkali solution.
What is electrochemical monitoring?
Determined by the metabolic rate and elimination based on the V/Q ratio of the lungs
What is production?
Regular cleaning, calibration checks, equipment maintenance and regular review of ongoing test quality.
What is quality assurance/ preventative maintenance?
Measurement of flows between 60-1000 L/min
What is a peak flow meter?
Parallel brass capillary tubes that monitors pressures and convert it into a flow signal.
What is Fleish pneumotachograph?
Nitrogen dioxide levels are obtained by converting NO2 to NO with a catalytic and chemical converter.
What is chemiluminescence monitoring?
Elevated after mouth-to-mouth or ingestion of carbonated beverages
What is gastric PCO2?
