What are the two factors that reduce lung volume?
smoking
What are the four factors affecting airway resistance in the lungs?
there are four important factors that effecting the lung resistance . 1- lung volume 2- density and viscosity of the air breathed. 3- contraction of smooth muscles of the air way. 4- diameter of the airway.
What does total lung capacity equals?
Total lung volume equals Vital Capacity + Residual Volume.
How is lung capacity measured and what factors can affect it?
Lung capacity is measured using a device called a spirometer, which calculates the volume of air a person can inhale and exhale. Factors that can affect lung capacity include age, gender, height, physical fitness, smoking habits, and certain medical conditions like asthma or COPD.
What are the complications of tidal volume?
Complications of tidal volume include barotrauma (lung damage from high pressures), volutrauma (lung damage from excessive stretch), and ventilator-associated lung injury. Inadequate tidal volume can lead to hypoventilation and hypercapnia, while excessive tidal volume can cause ventilator-induced lung injury. Close monitoring and adjustment of tidal volume is important to avoid these complications.
What is lung capacity meant by?
Your total lung capacity is the total volume of the lung after maximum inspiration. (average 6 litres).
The air remaining in the lung after a maximal expiration is the?
residual volume
What is an anterior and posterior diameter ratio for the lungs with breathing?
The anterior-posterior diameter ratio of the lungs with breathing is typically 1:2. During inspiration, the chest expands leading to an increase in the anterior-posterior diameter of the lungs. This ratio can vary depending on factors like lung volume and individual anatomy.
What are 2 factors that can change the volume of the gas?
pressure and the temperture
What is the lung volume that represents the total volume of exchangeable air?
vital capacity
What does Lung volume reduction do?
These procedures remove 20-30% of severely diseased lung tissue; the remaining parts of the lung are joined together
What units are maximum lung volume measured in?
inches
