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

What is an alveolar dead space?
An alveolar dead space is the volume of air in the alveoli of the lungs which does not partake in gas exchange.
What is difference between anatomical dead space and phyiological 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.
What is the Correct formula to calculate the alveolar minute ventilation?
the dead space must also be factored in, so the equation would be: RR(tidal volume-dead space)
Why respiratory minute volume does not represent all air that reaches the alveolar surface?
Due to the presence of dead space
Physiological dead air space is anatomic dead plus?
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.
How do you get alveolar ventilation rate?
To calculate alveolar ventilation rate, you need to multiply the tidal volume (the amount of air moved in and out of the lungs during normal breathing) by the respiratory rate (number of breaths per minute), and then subtract the dead space volume (the portion of inspired air that does not reach the alveoli). This gives you the amount of fresh air reaching the alveoli per minute.
What is alveolar ventilation refers to?
Alveolar volume is lung capacity. Alveoli are the air sacs in the bronchioles. How much air the lungs hold during both inspiration and expiration is lung capacity which is alveolar volume. Hope this helps
The respiratory disease that causes abnormal dilation of the alveolar space is?
emphysema
What respiratory disease causes abnormal dilation of the alveolar space?
emphysema
In which layer of the alveolar membrane are the cleanup cells located?
The cleanup cells, also known as alveolar macrophages, are located in the alveolar space within the alveolar membrane. They play a crucial role in clearing debris, bacteria, and other particles from the lungs to maintain respiratory health.
What does Alveolar Ventalation Rate mean?
Alveolar ventilation rate refers to the volume of air per minute that reaches the alveoli in the lungs for gas exchange. It is calculated by multiplying the tidal volume by the respiratory rate and subtracting the dead space volume. This measurement is important for assessing the efficiency of gas exchange in the lungs.
What is an alveolar rupture?
An alveolar rapture refers to a situation where the alveolus raptures as a result of increased trans alveolar pressure with less pressure in the adjacent intestinal space. The rapture is dangerous because the amount of pulmonary congestion or obstruction that prevents the expansion of the lung is immeasurable, thereby leaving no criteria for safe pressures.
