In a person with emphysema, there is a significant loss of intrinsic elastic recoil in the lung tissue. This loss of elastic recoil occurs as the disease destroys the walls of the alveoli. Airway resistance is also increased as the lung tissue in general becomes more flimsy and exerts less mechanical tethering on the surrounding airways. Thus the lung becomes overly compliant and expands easily. Conversely, a great effort is required to exhale as the lungs can no longer passively recoil and deflate. A noticeable and exhausting muscular effort is required for each exhalation. Thus a person with emphysema exhales slowly. Thus decreasing the tidal volume.

What is the tidal volume of an average 70kg adult?
Tidal volume is the volume of gas inhaled or exhaled during a normal breath. The tidal volume of an average adult is approximately 500 to 600 mL.
What is tidal volume measured in?
The volume of gas inspired or expired during each respiratory cycle.
How does the shape of the shorline affect a tide?
The shape of the coastline affect tides because of resonance. Resonance changes normal tide occilations. (see in the section of resonance, Hydrographic Volume II, Tide and Tidal Stream)
What is the approximate volume of inspiratory reserve volume?
inspiratory reserve volume= expiratory reserve volume + Tidal Volume - Vital capacity
What is the tidal volume in litres for an average adult?
500 millilitres
What is the volume of air inhaled or exhaled per breath?
The amount, called tidal volume, is basally about half a litre/500ml. But it, multiplies upon exertion.
What happened to the tidal volume during hyperventilation?
Tidal volume increased.
What happened to tidal volume during hyperventilation?
Tidal volume increases.
What changes in tidal volume might you see when someone has COPD?
Decrease lung and air volume in the amount of air exchange
What is the amount of air that moves into the respiratory system during a single respiratory cycle?
The amount of air that is inhaled or exhaled in one breath during unforced breathing is the tidal volume.
What is normal tidal volume in dogs?
a Rabbit weighing 2.4kg the tidal volume is 15.8ml
How does living in altitude influence tidal volume?
how does lining in high altitude influence tidal volume
What is tidal volume of the lung?
Tidal volume is the amount of swag in the air and the amount of banter in a toilet
What effects does exercise have on tidal volume?
The effects that exercise have on tidal volume is that they cause an increase to in tidal volume. This is due to the faster breathing in which allows the lungs to bring in more oxygen.
What is the difference between tidal volume and residual volume and pulmonary?
Tidal volume is the volume of air that moves in and goes out in asingle stroke, and is abut 500ml.
How does living in high altitudes influence tidal volume?
how does lining in high altitude influence tidal volume
What is the tidal volume of an average 70kg adult?
Tidal volume is the volume of gas inhaled or exhaled during a normal breath. The tidal volume of an average adult is approximately 500 to 600 mL.
