Function Residual Capacity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Function Residual Capacity = Residual Volume of Lung+Expiratory Reserve Volume
FRC = RV+ERV
This formula uses 3 Variables

Variables Used

Function Residual Capacity - (Measured in Cubic Meter) - Function Residual Capacity is It is the amount of air remaining in the lungs at the end of a normal exhalation.
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).
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.

STEP 1: Convert Input(s) to Base Unit

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

STEP 2: Evaluate Formula

Substituting Input Values in Formula

FRC = RV+ERV --> 1E-05+1.2E-05

Evaluating ... ...

FRC = 2.2E-05

STEP 3: Convert Result to Output's Unit

2.2E-05 Cubic Meter -->22 Milliliter (Check conversion here)

FINAL ANSWER

22 Milliliter <-- Function Residual Capacity

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. The average total lung capacity of an adult human male is about 6 litres of air.

How to Calculate Function Residual Capacity?

Function Residual Capacity calculator uses Function Residual Capacity = Residual Volume of Lung+Expiratory Reserve Volume to calculate the Function Residual Capacity, The Function Residual Capacity formula is defined as the amount of air remaining in the lungs at the end of a normal exhalation. It is calculated by adding together residual and expiratory reserve volumes. The normal value is about 1800 – 2200 mL. Function Residual Capacity is denoted by FRC symbol.

How to calculate Function Residual Capacity using this online calculator? To use this online calculator for Function Residual Capacity, enter Residual Volume of Lung (RV) & Expiratory Reserve Volume (ERV) and hit the calculate button. Here is how the Function Residual Capacity calculation can be explained with given input values -> 2.2E+7 = 1E-05+1.2E-05.

FAQ

What is Function Residual Capacity?

The Function Residual Capacity formula is defined as the amount of air remaining in the lungs at the end of a normal exhalation. It is calculated by adding together residual and expiratory reserve volumes. The normal value is about 1800 – 2200 mL and is represented as FRC = RV+ERV or Function Residual Capacity = Residual Volume of Lung+Expiratory Reserve Volume. 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) & 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.

How to calculate Function Residual Capacity?

The Function Residual Capacity formula is defined as the amount of air remaining in the lungs at the end of a normal exhalation. It is calculated by adding together residual and expiratory reserve volumes. The normal value is about 1800 – 2200 mL is calculated using Function Residual Capacity = Residual Volume of Lung+Expiratory Reserve Volume. To calculate Function Residual Capacity, you need Residual Volume of Lung (RV) & Expiratory Reserve Volume (ERV). With our tool, you need to enter the respective value for Residual Volume of Lung & Expiratory Reserve Volume and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
