tidal volume

The amount, called tidal volume, is basally about half a litre/500ml. But it, multiplies upon exertion.
What happens to residual volume, tidal volume, inspiratory reserve volume and expiratory reserve volume just after exercise while breathing deeply and rapidly? Do they increase, decrease or stay the same?
Earth's atmosphere has roughly a 0.04% of CO2 (by volume), that's about the percentage we inhale.

The Nitrogen Washout technique, also known as Fowler's method, is used to determine the anatomical dead space in the lungs. It does this by measuring the volume of gas that is in the conducting airways. An individual inhales 100% Oxygen, and then exhales into a Nitrogen Sampler. This Nitrogen Sampler does two things: it measures the percentage of Nitrogen in the exhaled air, and it also measures the volume of air that is exhaled. By taking the halfway point in the % of Nitrogen exhaled (the transitional phase) one can figure out the amount of Nitrogen expelled, as therefore the volume of dead space in the lungs.
The amount of air that is inhaled or exhaled in one breath during unforced breathing is the tidal volume.
the depth of respiration

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.
Respiratory volume or respiratory minute volume is the volume of air which can be inhaled or exhaled from a person's lung in one minute.It is normally consider when a person on a ventilator for breathing problem due to sickness or injury. It is calculated by taking the tidal volume( or lung volume ) and multiplying it by the respiratory rate( the number of breaths per minute a person is taking).
spirometry
- I'm not sure I understand what you are asking. A tidal volume is what we use to measure how many liters a person can hold in their lungs. It's normally about 10-15mls/kg of ideal body weight. That number can be used to identify certain respiratory diseases. Its also what most ventilators are set on when a person needs ventilatory support.
The residual volume is the portion of air in the respiratory tract that cannot be exhaled.
Inhaled air contains a greater volume of oxygen than carbon dioxide. Exhaled air is the opposite, since after the exchange of gases in the lungs the carbon dioxide in the blood is transferred into the lungs. Exhaled air contains a greater volume of carbon dioxide than oxygen. Also, there is more water vapour in exhaled air than inhaled air.
The ERV is the expiratory reserve volume, which is the amount of air that can be forcefully exhaled after a normal tidal volume exhalation.
The amount, called tidal volume, is basally about half a litre/500ml. But it, multiplies upon exertion.
Having a common cold usually creates swelling in your airways resulting hyperinflation in the lungs, making it hard to get a full breathe. Prolonged hyperinflation can cause auto peeps in the tidal volume, which mean that the air exhaled is much less then the air inhaled creating a buildup of carbon dioxide and eventually leading to respiratory failure. Your minute volume can decrease as well this is what makes you feel fatigued.
