|
Vital capacity
|
Maximum amount of air that can be exhaled after a maximum inhalation.
|
|
|
Visceral pleura
|
Membrane covering the outer surface of each lung.
|
|
|
Total lung capacity
|
Total amount of air that the lungs are capable of holding, including residual volume.
|
|
|
Tidal volume
|
Volume of air breathed in and out during a cycle of respiration.
|
|
|
Thoracic cavity
|
Chest cavity bounded by the ribs, sternum, vertebral column, and diaphragm, in which the lungs are housed.
|
|
|
Spirometer
|
Instrument that measures lung volumes; can be wet or dry.
|
|
|
Resting expiratory level
|
State of equilibrium in the respiratory system when Palv equals Patmos.
|
|
|
Respiratory kinematic analysis
|
Methods of estimating lung volumes from rib cage and abdominal movements.
|
|
|
Residual volume
|
Volume of air remaining in the lungs after a maximum exhalation that can-not be voluntarily expelled.
|
|
|
Relaxation pressures
|
Air pressures generated by the recoil forces of the respiratory system.
|
|
|
Pulmonary system
|
Part of the respiratory system that includes the lungs and airways.
|
|
|
Prephonatory chest wall movements
|
Positioning of the chest wall that facilitates the generation of pressures for speech production.
|
|
|
Pneumotachograph (pneumotachometer)
|
Instrument used to measure airflows during respiration.
|
|
|
Pleural linkage
|
The mechanism by which the lungs and thoracic cavity are linked together to function as a unit.
|
|
|
Pleural fluid
|
Fluid within the pleural space, having a negative pressure.
|
|
|
Plethysmograph
|
Instrument used to measure changes in the cross- sectional areas of the chest wall.
|
|
|
Parietal pleura
|
Membrane that lines the inner surface of the thoracic cavity.
|
|
|
Linearized magnetometers
|
Instrument used to measure movements of the chest wall.
|
|
|
Intercostals muscles
|
Made up of internal and external sets of muscles running between the ribs on both sides.
|
|
|
Inspiratory reserve volume
|
Amount of air that can be inhaled above tidal volume.
|
|
|
Functional residual capacity
|
Amount of air in the lungs and airways at the end of a normal quiet exhalation.
|
|
|
Expiratory reserve volume
|
Amount of air that can be exhaled below tidal volume.
|
|
|
Diaphragm
|
Muscle that makes up the floor of the thoracic cavity and is instrumental in respiration.
|
|
|
Dead air
|
Small amount of air not involved in oxygen– carbon dioxide exchange.
|
|
|
Chest-wall system
|
Part of the respiratory system that includes the rib cage, abdomen, and diaphragm.
|
|
|
Alveolar pressure
|
Pressure of the air within the alveoli of the lungs.
