Lung Volume & Capacity FRITZ

What is the inspiratory reserve volume?

How much forced inhale you can take in/how much inhale you can go past your normal breathing aka tidal volume. Can go up to 3 liters however, on average, it's 2 liters for humans.

What is tidal volume?

Is the amount of air that is exhaled and inhaled normally . Is not forced. Takes place when you're sleeping, eating, and doing daily task without forcing an exhale or inhaling. You're just doing it automatically/ naturally without giving it thought.

Can everyone hold 6 liters of air? Why or why not?

Not everyone can hold the same amount of air in their lungs because it differs from person to person. Age, size, fitness, and overall health can be factors that determine how much air a human can hold in their lungs.

What is the Residual Volume?

Since you can never completely exhale/get rid of ALL the air in your lungs, there's some air left over in there. That air left over in there is called the residual volume. This is about 1.2 liters.

When a person is giving a distressed person CPR, what are they trying to do to the lungs?

They are trying to help the distressed person use that residual volume of air to be used in their lungs to be used.

What does the Inspiratory Capacity consist of?

This contains the Inspiratory reserve volume and and tidal volume

What does the Functional Residual Capacity consist of?

This contains the expiratory reserve volume and the residual volume

What is the Functional Residual Capacity?

This is all of the air that you PUSH OUT/EXHALE naturally AND forcefully.

What is the Inspiratory Capacity?

This is all of the air that you TAKE IN naturally AND forcefully.

What is Total Lung Capacity?

This is all of the total air in your lungs! Consist of the expiratory reserve, inspiratory reserve, tidal volume, and residual volume.

What is the Expiratory Reserve Volume?

This is how much you can typically exhale past what you normally would aka tidal volume. It's approximately 2 liters however, on average, it's 1 liter for humans.

What is the Vital Capacity?

Vital Capacity is everything but the residual volume. This is the amount of air that a human can inhale and exhale , forcefully AND naturally.

The maximum amount of air that can be exhaled past tidal volume refers to __.

expiratory reserve volume

Functional residual capacity includes __.

expiratory reserve volume and residual volume

All of the air that stays in the lungs after tidal breathing is __. It would include the air from forced exhalation and air that is always there.

functional residual capacity

All of the air that can be inhaled is __, and it includes normal breathing as well as all the air to pull in past that point.

inspiratory capacity

Before diving in the water to swim, we often take a deep breath. In this case, we inhale past the normal breathing level and that extra inhaled air refers to the __.

inspiratory reserve volume

The amount of air that can never be truly exhaled refers to the __.

residual volume

While we sleep, we breath normally in and out at a traditional relaxed pace; this amount of normal in and out air refers to the __.

tidal volume

Inspiratory capacity includes __.

tidal volume and inspiratory reserve volume

Totaling about 6 liters, __ refers to the maximum amount of air to be held within the lungs.

total lung capacity

Accounting for 80% of lung capacity, __ is the maximum amount of air that can be inhaled or exhaled.

vital capacity

How many liters of air can the average person hold in their lungs?

6 liters

How much does vital capacity account for in the total lung capacity?

80%

How big is the tidal volume?

Approximately half a liter or 500 ml.

Lung capacity is built to help accommodate your unique _______ type.
