<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">Ventilation of the lungs involves the exchange of gases during inhalation and exhalation causing the movement of respiratory gases between alveolars and the atmosphere as a result of a pressure drop between alveolars and the atmosphere. During artificial ventilation what is most important is to keep specific mechanical parameters of the lungs such as total compliance of the respiratory system <italic>Cp</italic> (consisting of the lung and the thorax compliances) and the airway resistance <italic>Rp</italic> when the patient is ventilated. Therefore, as the main goal of this work and as the first step to use our earlier method of added lung compliance in clinical practice was: 1) to carry out computer simulations to compare the application of this method during different expiratory phases, and 2) to compare this method with the standard method for its accuracy.The primary tests of the added-compliance method of the main lung parameters measurement have been made using the RC mechanical model of the lungs.</abstract>
