Hypoxia: Causes, Symptoms, Tests, Diagnosis & Treatment
2022年5月12日 · This is called circulatory hypoxia (also called stagnant hypoxia or ischemic hypoxia). Congestive heart failure and blood clots can increase your risk of circulatory hypoxia. Anemic hypoxia. Anemic hypoxia happens when you don’t have enough red blood cells to carry oxygen from your lungs to other tissues.
Oxygen Transport in Normal and Pathological Situations: Defects …
Stagnant hypoxia, as its name implies, refers to situations in which blood flow is abnormally low as occurs in shock, syncope or other “low-flow” states. In terms of oxygen transport, decreased blood flow (hypoperfusion) is the primary limitation, and thus, the problem resides with the cardiovascular system.

2022年10月22日 · Stagnant/circulatory hypoxia: Poor blood flow leads to less oxygen available to the tissues. This may occur in one specific area or throughout the whole body. Histiotoxic hypoxia: Enough oxygen is taken in through the lungs and delivered to the tissues, but the body has difficulty using it.

2023年7月2日 · Stagnant (circulatory) hypoxia occurs when poor blood circulation impairs oxygen delivery to tissues. Causes of stagnant hypoxia include: Histotoxic hypoxia occurs when the blood has sufficient...

First, hypoxaemic hypoxia is where oxygen transport to and/or across the alveolus may become impaired. Second, circulatory or stagnant hypoxia exists where blood may be sufficiently oxygenated but transport to the tissues is prevented.
Hypoxic Hypoxia - an overview | ScienceDirect Topics
Stagnant hypoxia occurs when blood flow to the lung is abnormally low, such as during shock states, cardiac arrest, severe congestive heart failure, or abdominal compartment syndrome. The primary disturbance lies within the cardiovascular system.
Hypoxia | Definition, Types, & Physiological Effects | Britannica
2024年10月30日 · Stagnant hypoxia, in which blood flow through the capillaries is insufficient to supply the tissues, may be general or local. If general, it may result from heart disease that impairs the circulation, impairment of veinous return of blood, or trauma that induces shock. Local stagnant hypoxia may be due to any condition that reduces or prevents ...

2022年2月3日 · Examples of fast-changing normoxic to hypoxic environments are fast ascended on the mountain summits during mountaineering, military and rescue services and travels with fast transportation to altitude. Acute mountain sickness is well-known to occur due to extensive and fast decreases in P b, normally beginning at an altitude of above 2500 m.
Mechanisms of hypoxaemia and the interpretation of
2012年10月1日 · For example a healthy young adult breathing room air would be considered hypoxaemic with a PaO 2 under 12 kPa, whilst a healthy elderly person may have a PaO 2 of 10 kPa under the same conditions. Therefore, deciding what are abnormal results requires an understanding of the clinical context.
Mechanisms of hypoxaemia and the interpretation of arterial …
2021年10月1日 · Stagnant hypoxia This describes an inadequate delivery of oxygenated blood to the tissues. Oxygen delivery (DO 2 ) is the rate at which oxygen is transported from the lungs to the microcirculation and is the product of the cardiac output (Q) and the total oxygen content of …
