The value of Residual volume is found to be $1200$ ml in the case of males and $960$ ml in the case of females.ĭead space is a part of the respiratory tract, containing a part of inspired air not participating in a gaseous exchange with blood capillaries and the amount of air present in the dead space is known as the dead space air. Residual volume is the amount of air found in both the lungs after a forceful expiration. Various lung diseases are diagnosed by the physiological dead space volume.
Residual volume is a normal phenomenon but the dead space volume(physiological dead space) occurs due to lack of the blood supply into the alveoli resulting in the improper gaseous exchange of the alveoli. Hint: No, residual volume and dead space volume are not synonymous.
