Let us learn about respiratory volumes
Respiratory volumes are those volumes of air which are exchanged during breathing; they are important indicators of the functioning of the respiratory system & can be measured through the use of a spirometer. We have 2 styles of spirometer: 1st has a turbine which rotates as air passes through it & this rotation is geared down to drives the movement of a needle which indicates the volume of air. The 2nd secure or captures air in an inverted chamber the volume being indicated by the increase of the chamber in a bath of water.
Different degrees of effort in breathing result in different volumes of air being moved in of the lungs or out of the lungs. The measurement of such air volumes is said to be as spirometry, & these measurements reveal the presence of 4 distinct respiratory volumes. Example: 1) the amount of air that enters the lungs during a normal 2) quiet inspiration is about 500 cubic centimeters. 3) Approximately the same amount leaves during a normal expiration. 4) This volume is termed the tidal volume.
In our next blog we shall learn about true solutions I hope the above explanation was useful.Keep reading and leave your comments.
