LUNG FUNCTION

You may not think about the importance of your lung health until you experience a breathing problem. Your lungs provide oxygen and keep every other organ functioning by removing carbon dioxide from your body. Genetics, disease, and the environment can affect the health of your lungs and cause respiratory problems.

Airway Resistance RAW

The airway resistance, which in science and medicine is abbreviated as Raw. For air to move into or out of your lungs, it must want to, and it has to overcome friction, the force that stops two things from sliding past each other. Airway resistance is a measure of the resistance to lung airflow caused by friction. The resistance of your lung to airflow is a determinant of how easy it is to breathe; That’s why scientists like to measure it. Knowing the airway resistance helps doctors tell if your lungs are functioning normally. 

The first formula for airway resistance involves figuring out the change in pressure from where air enters (your mouth) to where it ends up, the part of the lung called the alveoli. The pressure of the lung where air enters is the same as the pressure of the atmosphere, while the pressure of the alveoli (Palv) is determined by other factors. The most common unit of pressure used for the lung is centimeters of water (cmH2O). The other part involves flow rate (V dot), or how fast the air flows. Since air isn’t a solid, it’s most often measured by how much volume in liters it occupies, and since it moves so fast, time is usually measured in second. 

  

Arterial Oxygen Content (PaCO2) 

The definition is the amount of oxygen bound to hemoglobin (1.34 * Hb * SaO2) plus the oxygen dissolved in plasma (0.0031 * PaO2). The arterial oxygen content equation: CaO2 = (1.34 * Hb * SaO2) + (0.0031 * PaO2). The normal oxygen combining capacity is 1.39 mls/gram, however due to abnormal forms of hemoglobin such as carboxyhemoglobin and methemoglobin this value is reduced to 1.34 mls/gram. Hb is Hemoglobin, the normal Hb for males is 14-20 g/dl and females 12-15 g/dl. SaO2 is the percentage of available hemoglobin that is saturated with oxygen, this value is from a direct measurement of an arterial blood gas. 0.0031 is the solubility coefficient of oxygen at body temperature. PaO2 is the partial pressure of oxygen in arterial blood not bound to hemoglobin.

  

Total Lung Capacity (TLC)

The inspiratory capacity plus the functional residual capacity; the volume of air contained in the lungs at the end of a maximal inspiration. The average total lung capacity of an adult human male is about 6 litres of air. Tidal breathing is normal, resting breathing; the tidal volume is the volume of air that is inhaled or exhaled in only a single such breath.

  

Vital Capacity (VC)

This is the maximum amount of air a person can expel from the lungs after a maximum inhalation. It is equal to the sum of inspiratory reserve volume, tidal volume, and expiratory reserve volume.
