What is the difference between pulmonary and alveolar ventilation?

nothing


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.


In COPD the PaCO2 will increase but the ventilation will not increase why?

ecause of air trapping and ineffective alveolar ventilation


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


What is the best indication of the adequacy of alveolar ventilation?

The best indication of the adequacy of alveolar ventilation is the partial pressure of carbon dioxide (PaCO2) in arterial blood. This measurement reflects how effectively the lungs are removing carbon dioxide from the body, which is a waste product of metabolism. Proper alveolar ventilation ensures that PaCO2 levels remain within the normal range.


What is the volume of gas that reaches the respiratory zone of the lungs called?

alveolar ventilation


What is the ventilation rate of Industrial Ventilation?

The ventilation rate of industrial ventilation should exceed the supply rate by 10%. There is a detailed description of these rates in the Lab Ventilation ACH Rates Standards and Guidelines manual.


What is function of ventilation?

The main function of the pulmonary vein is to carry oxygenated blood from the lungs to the left atrium. Then it is transferred to the aorta, which takes the blood to the head and arms.


What is contributing to the decreased alveolar ventilation?

Decreased alveolar ventilation can be caused by factors such as respiratory muscle weakness, lung diseases like chronic obstructive pulmonary disease (COPD), airway obstruction, or reduced respiratory drive from the brain. It can also be influenced by environmental factors such as high altitudes or poor air quality.


The volume of air available for gas exchange per minute is called what?

The volume of air available for gas exchange per minute is called the minute ventilation. It is calculated by multiplying the tidal volume (amount of air inhaled or exhaled during normal breathing) by the respiratory rate (number of breaths per minute).


Is alveolar ventilation the same as alveolar respiration?

If we think of the lungs as trees branching out, the alveoli are at the end. They are made of up clusters of small delicate sacs. This is where the oxygen you breathe in seeps across into the blood and the carbon dioxide (a "waste product" of all the things the body makes and does) comes out of the blood (and is then breathed out). It is the delicate structure and nearness to the blood vessels that allow this passage of oxygen in and carbon dioxide out. Pretty cool!


How does increased ventilation rate affect arterial blood?

It will induce a respiratory alkalosis, as carbon dioxide is washed out of the blood by the increased ventilation rate.
