Study Notes

Respiratory System Diagnostics

Pulmonary Function Analyzers are used to measure different aspects of respiratory function, including volumes and flow rates.
ERV (Expiratory Reserve Volume): The maximum amount of air that can be exhaled after a normal breath.
FEV1 (Forced Expiratory Volume in 1 second): The volume of air exhaled in the first second of a forced vital capacity (FVC) test.
FEV1/FVC: The ratio of FEV1 to FVC, expressed as a percentage.
FRC (Functional Residual Capacity): The amount of air remaining in the lungs after a normal breath.
FVC (Forced Vital Capacity): The maximum amount of air that can be exhaled after a full inhalation.
IC (Inspiratory Capacity): The maximum volume of air that can be inhaled after a normal breath.
IRV (Inspiratory Reserve Volume): The maximum amount of air that can be inhaled after a full inhalation.
MV (Minute Ventilation): The total volume of air exhaled per minute.
MVV (Maximum Voluntary Ventilation): The maximum volume of air that can be breathed per minute by voluntary effort.
RV (Residual Volume): The amount of air remaining in the lungs after a maximal exhalation.
TLC (Total Lung Capacity): The total amount of air the lungs can hold after a maximal inhalation.
VC (Vital Capacity): The volume of air that can be expelled from the lungs after a maximal inhalation.
VT (Tidal Volume): The volume of air inhaled and exhaled during a single breathing cycle.
Incentive Spirometer: A simple device that helps patients to keep up breathing exercises.
Graphing Spirometer: A more complex spirometer that measures volume, pressure, and flow rates.
Pulmonary Function Analyzer (PFA): Uses flow transducers and a computer system to analyze respiratory function.
Respiration Monitors: Used to detect variations in impedance of the chest, which can be used to monitor respiration.
Impedance Pneumography: Uses a weak electrical current to measure changes in impedance across the chest, which can be used to monitor respiration.
Capnography Monitors: Measure the levels of carbon dioxide in exhaled breath.
Capnograph: Uses an infrared sensor to measure CO2 levels in exhaled breath.
Oxygen Analyzers: Measure the levels of oxygen in gases or liquids.
Bronchoscopy Systems: Allows for visual examination of the upper respiratory system using a bronchoscope.
Bronchoscope: A tube-like instrument with optical channels, hollow sections, and a camera sensor to view and perform procedures within the respiratory system.

Bronchoscope Types

Flexible bronchoscopes: Thinner and more flexible, allowing them to reach further into the bronchial passages.
Rigid bronchoscopes: Allow for the introduction of instruments for biopsies, dilations, or burning of small growths.
Distal imaging: Some new bronchoscopes have imaging chips mounted on the distal end, eliminating some transmission problems associated with traditional fiber optics.
