Asthma
Asthma is a common long-term inflammatory disease of the airways of the lungs.

Atmosphere of Earth
The atmosphere of Earth is the layer of gases, commonly known as air, that surrounds the planet Earth and is retained by Earth's gravity.

Base of lung
The base of the lung is broad, concave, and rests upon the convex surface of the diaphragm, which separates the right lung from the right lobe of the liver, and the left lung from the left lobe of the liver, the stomach, and the spleen.

Blood
Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.
New!!: Ventilation/perfusion ratio and Blood · See more »
Breathing
Breathing (or respiration, or ventilation) is the process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly by bringing in oxygen and flushing out carbon dioxide.
New!!: Ventilation/perfusion ratio and Breathing · See more »
Chronic obstructive pulmonary disease
Chronic obstructive pulmonary disease (COPD) is a type of obstructive lung disease characterized by long-term breathing problems and poor airflow.

Compliance (physiology)
Compliance is the ability of a hollow organ (vessel) to distend and increase volume with increasing transmural pressure or the tendency of a hollow organ to resist recoil toward its original dimensions on application of a distending or compressing force.
New!!: Ventilation/perfusion ratio and Compliance (physiology) · See more »
Dead space (physiology)
In physiology, dead space is the volume of air which is inhaled that does not take part in the gas exchange, either because it (1) remains in the conducting airways, or (2) reaches alveoli that are not perfused or poorly perfused.

Fick's laws of diffusion
Fick's laws of diffusion describe diffusion and were derived by Adolf Fick in 1855.
New!!: Ventilation/perfusion ratio and Fick's laws of diffusion · See more »
Gravity
Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward (or gravitate toward) one another.
New!!: Ventilation/perfusion ratio and Gravity · See more »
Heart
The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system.
New!!: Ventilation/perfusion ratio and Heart · See more »
Hepatopulmonary syndrome
In medicine, hepatopulmonary syndrome is a syndrome of shortness of breath and hypoxemia (low oxygen levels in the blood of the arteries) caused by vasodilation (broadening of the blood vessels) in the lungs of patients with liver disease.

Hydrostatics
Fluid statics or hydrostatics is the branch of fluid mechanics that studies fluids at rest.
New!!: Ventilation/perfusion ratio and Hydrostatics · See more »
Lung
The lungs are the primary organs of the respiratory system in humans and many other animals including a few fish and some snails.
New!!: Ventilation/perfusion ratio and Lung · See more »
Perfusion
Perfusion is the passage of fluid through the circulatory system or lymphatic system to an organ or a tissue, usually referring to the delivery of blood to a capillary bed in tissue.
New!!: Ventilation/perfusion ratio and Perfusion · See more »
Pulmonary alveolus
A pulmonary alveolus (plural: alveoli, from Latin alveolus, "little cavity") is a hollow cavity found in the lung parenchyma, and is the basic unit of ventilation.
New!!: Ventilation/perfusion ratio and Pulmonary alveolus · See more »
Pulmonary edema
Pulmonary edema is fluid accumulation in the tissue and air spaces of the lungs.
New!!: Ventilation/perfusion ratio and Pulmonary edema · See more »
Pulmonary embolism
Pulmonary embolism (PE) is a blockage of an artery in the lungs by a substance that has moved from elsewhere in the body through the bloodstream (embolism).
New!!: Ventilation/perfusion ratio and Pulmonary embolism · See more »
Pulmonary shunt
A pulmonary shunt is a pathological condition which results when the alveoli of the lungs are perfused with blood as normal, but ventilation (the supply of air) fails to supply the perfused region.
New!!: Ventilation/perfusion ratio and Pulmonary shunt · See more »
Ratio
In mathematics, a ratio is a relationship between two numbers indicating how many times the first number contains the second.
New!!: Ventilation/perfusion ratio and Ratio · See more »
Respiration (physiology)
In physiology, respiration is defined as the movement of oxygen from the outside environment to the cells within tissues, and the transport of carbon dioxide in the opposite direction.
New!!: Ventilation/perfusion ratio and Respiration (physiology) · See more »
Respiratory failure
Respiratory failure results from inadequate gas exchange by the respiratory system, meaning that the arterial oxygen, carbon dioxide or both cannot be kept at normal levels.
New!!: Ventilation/perfusion ratio and Respiratory failure · See more »
Ventilation perfusion mismatch
Ventilation Perfusion mismatch or "V/Q defects" are defects in total lung ventilation perfusion ratio.
New!!: Ventilation/perfusion ratio and Ventilation perfusion mismatch · See more »
Ventilation/perfusion scan
A ventilation/perfusion lung scan, also called a V/Q lung scan, is a type of medical imaging using scintigraphy and medical isotopes to evaluate the circulation of air and blood within a patient's lungs, in order to determine the ventilation/perfusion ratio.
New!!: Ventilation/perfusion ratio and Ventilation/perfusion scan · See more »
Volumetric flow rate
In physics and engineering, in particular fluid dynamics and hydrometry, the volumetric flow rate (also known as volume flow rate, rate of fluid flow or volume velocity) is the volume of fluid which passes per unit time; usually represented by the symbol (sometimes). The SI unit is m3/s (cubic metres per second).
