Dead space volume is when some of the inspired air fills the conducting respiratory passageways and never contributes to gas exchange in the alveoli.

An anatomic dead space is a volume of conducting airways of the lung, as measured by a cast of the airways.
An alveolar dead space is the volume of air in the alveoli of the lungs which does not partake in gas exchange.

Dead space volume
the dead space must also be factored in, so the equation would be: RR(tidal volume-dead space)
ANATOMICAL DEAD SPACEThe volume of the conducting airways of the nose,mouth,trachea down to the level of alveoli representing dead portion of inspired gas unavailable of exchange of gases with pulmonary capilary blood. PHYSIOLOGICAL DEAD SPACEIt is the combination of anatomical dead space and alveolar dead space.where as alveolar dead space is the space occupied by gas which is transported to the alveoli but does not meet blood across the alveolar capillary membrane.
no you can't. Just turn down the volume
Due to the presence of dead space
Physiological dead space includes both anatomical dead space (air that fills the conducting airways where no gas exchange occurs) and alveolar dead space (alveoli that receive inadequate blood supply for gas exchange). It represents the total volume of the respiratory system that does not participate in gas exchange.
the air that enters the respiratory tract remaining in the conducting zone pasageways and never reaches the alveoli.
Alveolar dead space is the difference between anatomical and physiologic dead space, representing the space of alveoli occupied by air that does not participate in alveolar ventillation (oxygen-carbon di oxide exchange). Anatomical dead space: the Airways of mouth, nose, pharynx, larynx, trachea, bronchi, and the broncheoles. Equipment dead space is the volume of equipment that occurs in rebreathing of gases. Physiologic dead space is the sum of the anatomic and alveolar dead spaces Its volume VD is determined by measuring the partial pressure of carbon di oxide in a sample of exhaled gas (PE) and with tidal volum e(VT) using the formula VD/VT =[ (PCo2-PECo2)/PaCo2
