Total Lung Capacity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Lung Capacity = Inspiratory Reserve Volume+Tidal Volume+Expiratory Reserve Volume+Residual Volume of Lung
TLC = IRV+TV+ERV+RV
This formula uses 5 Variables

Variables Used

Total Lung Capacity - (Measured in Cubic Meter) - Total Lung Capacity is the maximum volume of air the lungs can accommodate or sum of all volume compartments or volume of air in lungs after maximum inspiration.
Inspiratory Reserve Volume - (Measured in Cubic Meter) - Inspiratory Reserve Volume is the additional volume of air that can be inspired at the end of a normal or tidal inspiration.
Tidal Volume - (Measured in Cubic Meter) - Tidal Volume is the amount of air that moves in or out of the lungs with each respiratory cycle.
Expiratory Reserve Volume - (Measured in Cubic Meter) - Expiratory Reserve Volume is the volume of air that can be exhaled forcibly after exhalation of normal tidal volume. The normal adult value is 700-1200ml.
Residual Volume of Lung - (Measured in Cubic Meter) - Residual Volume of Lung is the volume of air remaining in the lungs after maximal exhalation. Normal adult value is averaged at 1200ml(20‐25 ml/kg).

STEP 1: Convert Input(s) to Base Unit

Inspiratory Reserve Volume: 10 Milliliter --> 1E-05 Cubic Meter (Check conversion here)
Tidal Volume: 10 Milliliter --> 1E-05 Cubic Meter (Check conversion here)
Expiratory Reserve Volume: 12 Milliliter --> 1.2E-05 Cubic Meter (Check conversion here)
Residual Volume of Lung: 10 Milliliter --> 1E-05 Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

TLC = IRV+TV+ERV+RV --> 1E-05+1E-05+1.2E-05+1E-05

Evaluating ... ...

TLC = 4.2E-05

STEP 3: Convert Result to Output's Unit

4.2E-05 Cubic Meter -->42 Milliliter (Check conversion here)

FINAL ANSWER

42 Milliliter <-- Total Lung Capacity

Total Lung Capacity

Go Total Lung Capacity = Inspiratory Reserve Volume+Tidal Volume+Expiratory Reserve Volume+Residual Volume of Lung

Vital Capacity of Lung

Go Vital Capacity of Lung = Tidal Volume+Inspiratory Reserve Volume+Expiratory Reserve Volume

Airway Resistance

Go Airway Resistance = (Atmospheric Pressure-Alveolar Pressure)/Volumetric Airflow

Function Residual Capacity

Go Function Residual Capacity = Residual Volume of Lung+Expiratory Reserve Volume

Inspiratory capacity of Lung

Go Inspiratory Capacity = Tidal Volume+Inspiratory Reserve Volume

Airway Conductance

Go Airway Conductance = 1/Airway Resistance

Total Lung Capacity Formula

Total Lung Capacity = Inspiratory Reserve Volume+Tidal Volume+Expiratory Reserve Volume+Residual Volume of Lung
TLC = IRV+TV+ERV+RV

What is Lung Volume?

Lung volumes are also known as respiratory volumes. It refers to the volume of gas in the lungs at a given time during the respiratory cycle. Lung capacities are derived from a summation of different lung volumes. Lung volumes measurement is an integral part of pulmonary function test. These volumes tend to vary, depending on the depth of respiration, ethnicity, gender, age, body composition and in certain respiratory diseases.

How to Calculate Total Lung Capacity?

Total Lung Capacity calculator uses Total Lung Capacity = Inspiratory Reserve Volume+Tidal Volume+Expiratory Reserve Volume+Residual Volume of Lung to calculate the Total Lung Capacity, The Total Lung Capacity formula is defined as the maximum volume of air the lungs can accommodate or sum of all volume compartments or volume of air in lungs after maximum inspiration. Total Lung Capacity is denoted by TLC symbol.

How to calculate Total Lung Capacity using this online calculator? To use this online calculator for Total Lung Capacity, enter Inspiratory Reserve Volume (IRV), Tidal Volume (TV), Expiratory Reserve Volume (ERV) & Residual Volume of Lung (RV) and hit the calculate button. Here is how the Total Lung Capacity calculation can be explained with given input values -> 4.2E+7 = 1E-05+1E-05+1.2E-05+1E-05.

FAQ

What is Total Lung Capacity?

The Total Lung Capacity formula is defined as the maximum volume of air the lungs can accommodate or sum of all volume compartments or volume of air in lungs after maximum inspiration and is represented as TLC = IRV+TV+ERV+RV or Total Lung Capacity = Inspiratory Reserve Volume+Tidal Volume+Expiratory Reserve Volume+Residual Volume of Lung. Inspiratory Reserve Volume is the additional volume of air that can be inspired at the end of a normal or tidal inspiration, Tidal Volume is the amount of air that moves in or out of the lungs with each respiratory cycle, Expiratory Reserve Volume is the volume of air that can be exhaled forcibly after exhalation of normal tidal volume. The normal adult value is 700-1200ml & Residual Volume of Lung is the volume of air remaining in the lungs after maximal exhalation. Normal adult value is averaged at 1200ml(20‐25 ml/kg).

How to calculate Total Lung Capacity?

The Total Lung Capacity formula is defined as the maximum volume of air the lungs can accommodate or sum of all volume compartments or volume of air in lungs after maximum inspiration is calculated using Total Lung Capacity = Inspiratory Reserve Volume+Tidal Volume+Expiratory Reserve Volume+Residual Volume of Lung. To calculate Total Lung Capacity, you need Inspiratory Reserve Volume (IRV), Tidal Volume (TV), Expiratory Reserve Volume (ERV) & Residual Volume of Lung (RV). With our tool, you need to enter the respective value for Inspiratory Reserve Volume, Tidal Volume, Expiratory Reserve Volume & Residual Volume of Lung and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
