## Airway Resistance Solution

STEP 0: Pre-Calculation Summary
Formula Used
Airway Resistance = (Atmospheric Pressure-Alveolar Pressure)/Volumetric Airflow
RAW = (Patm-PA)/
This formula uses 4 Variables
Variables Used
Airway Resistance - Airway Resistance is the change in transpulmonary pressure needed to produce a unit flow of gas through the airways of the lung.
Atmospheric Pressure - (Measured in Pascal) - Atmospheric pressure, also known as barometric pressure, is the pressure within the atmosphere of Earth.
Alveolar Pressure - (Measured in Pascal) - Alveolar Pressure is the pressure of air inside the lung alveoli.
Volumetric Airflow - (Measured in Meter³ per Second) - Volumetric Airflow is the volumetric flow rate (also known as volume flow rate, rate of fluid flow, or volume velocity) is the volume of fluid which passes per unit time.
STEP 1: Convert Input(s) to Base Unit
Atmospheric Pressure: 101325 Pascal --> 101325 Pascal No Conversion Required
Alveolar Pressure: 10 Centimeter Water (4°C) --> 980.665 Pascal (Check conversion here)
Volumetric Airflow: 10 Centimeter³ per Second --> 1E-05 Meter³ per Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
RAW = (Patm-PA)/v̇ --> (101325-980.665)/1E-05
Evaluating ... ...
RAW = 10034433500
STEP 3: Convert Result to Output's Unit
10034433500 --> No Conversion Required
10034433500 <-- Airway Resistance

## What is airway resistance?

The definition of airway resistance is the change in transpulmonary pressure needed to produce a unit flow of gas through the airways of the lung. More simply put, it is the pressure difference between the mouth and alveoli of the lung, divided by airflow.

## How to Calculate Airway Resistance?

Airway Resistance calculator uses Airway Resistance = (Atmospheric Pressure-Alveolar Pressure)/Volumetric Airflow to calculate the Airway Resistance, The Airway Resistance formula is defined as the resistance of the respiratory tract to airflow during inhalation and exhalation. Airway resistance can be measured using plethysmography. Airway Resistance is denoted by RAW symbol.

How to calculate Airway Resistance using this online calculator? To use this online calculator for Airway Resistance, enter Atmospheric Pressure (Patm), Alveolar Pressure (PA) & Volumetric Airflow (v̇) and hit the calculate button. Here is how the Airway Resistance calculation can be explained with given input values -> 1.003E+10 = (101325-980.665)/1E-05.
