Respiratory 2 Flashcards
In horses, 02 increases in a _______ manner with speed
Linear
__________ animals have higher surface area/body weight ratio and consume more oxygen per kg of body weight
Smaller
What ventilation is the amount of oxygen required to reach the lungs?
Minute ventilation
What is the sum of the air volume that enters the perused alveoli and volume that remains the physiological dead space?
VT (tidal volume)
What ventilation is the fresh air available for gas exchange?
Alveolar ventilation
Vd/Tt (dead space/tidal volume) ratio tells the fraction of each breath that ventilates ___________ dead space?
Physiological
What percent of VD/VT do dogs have?
~33%
What percent Vd/Vt do cattle and horses have?
50-70%
Changes in tidal volume, ___________ frequency, or both, can alter the amount of air ventilating the alveoli per min
Respiratory
DeltaP determines whether air enters or leaves the _______
