which physiologic principle will result in an increase in alveolar/alveoli dead space?

It is defined as VD=Dead Space Volume×Respiratory RateVD=Dead Space Volume×Respiratory Rate.Īdditionally, minute ventilation can be described as the sum of alveolar and dead space ventilation, provided that the respiratory rate used to derive them is in terms of breaths per minute.

Dead space ventilation (VD): The amount of air per unit of time that is not involved in gas exchange, such as the air that remains in the conducting zones.

It is defined as VA=(Tidal Volume−Dead Space Volume)×Respiratory RateVA=(Tidal Volume−Dead Space Volume)×Respiratory Rate

Alveolar ventilation (VA): The amount of gas per unit of time that reaches the alveoli and becomes involved in gas exchange.

It can be defined as VE=Tidal Volume×Breaths Per MinuteVE=Tidal Volume×Breaths Per Minute

Minute ventilation (VE): The amount of air entering the lungs per minute.

The three main types of ventilation rates used in respiratory physiology are: The volume of air can refer to tidal volume (the amount inhaled in an average breath) or something more specific, such as the volume of dead space in the airways.

Ventilation is generally expressed as volume of air times a respiratory rate.

In respiratory physiology, the ventilation rate is the rate at which gas enters or leaves the lung.
