|
accessory muscles of expiration (4) |
rectus abdominis external oblique internal oblique transverses abdominis |
|
|
tidal volume (TV) |
volume of air inhaled and exhaled during one cycle of respiration, approx. 500 mL |
|
|
inspiratory reserve volume (IRV) |
volume of air that can be inhaled above tidal volume |
|
|
expiratory reserve volume (ERV) |
volume of air that can be exhaled below tidal volume |
|
|
residual volume (RV) |
volume of air remaining in lungs after maximum exhalation; cannot be voluntarily expired |
|
|
vital capacity (VC) |
volume of air that can be exhaled following a maximum inhalation (TV + IRV + ERV); approx. 5,000mL |
|
|
inspiratory capacity (IC) |
volume of air that can be inhaled from end-expiratory level (TV + IRV) |
|
|
functional residual capacity (FRC) |
volume of air remaining in the lungs and airways at the end-expiratory level (ERV + RV) |
|
|
total lung capacity (TLC) |
total amount of air that can be held in the lungs (TV + IRV + ERV + RV) |
|
|
end-expiratory level (EEL) |
the endpoint of a quiet expiration |
|
|
resting expiratory level (REL) |
state of equilibrium in the respiratory system in which alveolar and atmospheric pressures are equalized |
|
|
five changes that occur when switching from life breathing to speech breathing |
location of air intake (life = nasal, speech = oral) ratio of time for inhalation vs. exhalation (life = 40:60, speech = 10:90) volume of air inspired (life = 500mL, 10% VC, speech = variable, 20-25%) muscle activity for exhalation (see notes) abdominal displacement (life = outward, speech = inward) |
