Speech Breathing Flashcards
Ratio of air required in quiet breathing in a cycle
inspiration: expiration
40:60
Ratio of air required during speech in a cycle
inspiration: expiration
10: 90
Spirometer used to….
used to measure the volume of air inspired and expired
Spirometer produce measures of …..
- respiratory lung volume
- respiratory capacities
Respiratory Lung volumes are….
volume of air associated with a specific phase of the respiratory cycle
Respiratory capacities refers to
combined volumes that express physiological limits
Tidal volume (TV)
the volume of air exchanged in one cycle of respiration
Inspiratory reserve volume (IRV)
the volume of air that can be inhaled after a tidal inspiration
Expiratory reserve volume (ERV)
the vol of air expiredfollowing tidal expiration
Residual volume (RV)
the vol of air remaining in the lungs after a maximum exhalation
Manometer used for
measuring respiratory pressure
design of manometer
to lift a column of liquid
How many mL of air in each cycle during quiet breathing?
500 mL
600 for males & 450 for females
1 minute how much air?
6,000 - 8,000 mL
minute volume
air involved in 1 minute of respiration
tidal volume
vol of air inspired and expired during each quiet breathing cycle
How many respiratory cycles in one minute?
Adults 12-18 cycles/min
where is the respiratory center that responds to these blood gasse and trigger contraction of your diaphragm to maintain quiet breathing?
Medulla oblongata
Which organ monitors CO2 and O2 in your body?
brainstem
3 passive expiration forces
- Elastic recoil
- Torque
- Gravity
elastic recoil causes….
The recoil cause the structures to return to their coupled equilibrium
Torque ….
of twisted rib cartilage connecting the ribs to the sternum
Gravity
contributes lowering the ribs > depending somewhat on body position
TLC
Total lung capacity
