Pulmonary Compliance |
Measure of distensibility of the lungs and thorax |
|
|
Abdominal Breathing |
Visible movements of the abdomen caused by compression of the viscera by the diaphragm |
|
|
Costal Breathing |
Pronounced movement of the rib cage |
|
|
Paradoxical Breathing |
Abdoment is 'sucked' in during inspiration and bulges out during expiration |
|
|
Spirometry |
Versatile test of pulmonary physiology |
|
|
Tidal Volume |
The amount of gas expired per breath |
|
|
Vital Capacity |
Maximal volume of air that can be forcible exhaled
VC= Tidal Volume + IRV + ERV |
|
|
Alveolar Ventilation |
Volume of fresh gas entering the alveoli in each breath |
|
|
Inspiratory Reserve Volume |
Additional volume of air that can be forcibly inhaled following a normal inspiration |
|
|
Expiratory Reserve Volume |
Additional volume of air that can be forcibly exhaled following a normal expiration |
|
|
Residual Volume |
Volume of air remaining in the lungs after maximal expiration |
|
|
Functional Residual Capacity |
Volume of air remaining in the lungs at the end of a normal expiration |
|
|
Total Lung Capacity |
Volume of air in the lungs at the end of a maximal inspiration |
|
|
Minute Volume |
Amount of gas expired per minute |
|
|
Dead Space |
Not all gas entering the respiratory tract is involved in gaseous exchange |
|
|
Anatomical Dead Space |
Volume of the conducting airways |
|
|
Physiological Dead Space |
Volume of gas that is inspired but takes no part in gas exchange |
|
|
Capnographs |
Measure end-tidal carbon dioxide |
|
|
Wright Spirometer |
Measure tidal volume and minute volume |
|
|
Pneumotachograph |
Measures gas flow |
|
|
Pneumothorax |
Presence of air in the pleural cavity |
|
|
Tension Pneumothorax |
When a wound acts as a one way valve, pressure in the thorax continues to rise with each breath (true emergency and life threatening) |
|
|
Cyanosis |
Blue discolouration of the skin and mucous membranes |
|
|
Emphysema |
Gradual damage to the air sacs in the lungs making progressively more short of breath |
|
|
Thoracentesis |
Remove fluid from the pleural cavity |
|
|
Pleural Effusion |
Collection of excess fluid between the visceral and parietal pleura (pleural cavity) |
