Airway resistance is not constant. As shown above airway resistance is markedly affected by changes in the diameter of the airways. Therefore, diseases affecting the respiratory tract can increase airway resistance. Airway resistance can also change over time. During an asthma attack the airways constrict causing an increase in airway resistance.

Impulse oscillometry (IOS), also known as respiratory oscillometry, forced oscillatory technique (FOT), or just oscillometry, is a non-invasive lung function test that measures the mechanical properties of the respiratory system, particularly the upper and intrathoracic airways, lung tissue and chest wall, usually during the patient's tidal breathing (the way someone breathes when they are ...
Continuous positive airway pressure (CPAP) is a form of positive airway pressure (PAP) ventilation in which a constant level of pressure greater than atmospheric pressure is continuously applied to the upper respiratory tract of a person. The application of positive pressure may be intended to prevent upper airway collapse, as occurs in ...
Obstructive lung disease is a category of respiratory disease characterized by airway obstruction. Many obstructive diseases of the lung result from narrowing (obstruction) of the smaller bronchi and larger bronchioles, often because of excessive contraction of the smooth muscle itself. It is generally characterized by inflamed and easily ...
Pendelluft. Pendelluft (Derived from the German words for pendulum and air. [1]) refers to the movement of gas between two regions of the lung, usually between regions of differing compliance or airway resistance. Pendelluft is an important physiological concept to take into account during mechanical ventilation, particularly in patients with ...
Airway management includes a set of maneuvers and medical procedures performed to prevent and relieve airway obstruction. This ensures an open pathway for gas exchange between a patient's lungs and the atmosphere. [1] This is accomplished by either clearing a previously obstructed airway; or by preventing airway obstruction in cases such as ...
Inspired air is humidified, improving the quality of airway mucus. [2] In humans, about a third of every resting breath has no change in O 2 and CO 2 levels. In adults, it is usually in the range of 150 mL. [3] Dead space can be increased (and better envisioned) by breathing through a long tube, such as a snorkel. Although one end of the ...
