  2. Hypoxia (medicine) - Wikipedia

    en.wikipedia.org/wiki/Hypoxia_(medicine)

    A special case of hypoxic breathing gas is encountered in deep freediving where the partial pressure of the oxygen in the lung gas is depleted during the dive, but remains sufficient at depth, and when it drops during ascent, it becomes too hypoxic to maintain consciousness, and the diver loses consciousness before reaching the surface. [15] [10]

  3. Generalized hypoxia - Wikipedia

    en.wikipedia.org/wiki/Generalized_hypoxia

    Generalized hypoxia is a medical condition in which the tissues of the body are deprived of the necessary levels of oxygen due to an insufficient supply of oxygen, which may be due to the composition or pressure of the breathing gas, decreased lung ventilation, or respiratory disease, any of which may cause a lower than normal oxygen content in the arterial blood, and consequently a reduced ...

  4. Pulmonary heart disease - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_heart_disease

    The symptoms/signs of pulmonary heart disease (cor pulmonale) can be non-specific and depend on the stage of the disorder, and can include blood backing up into the systemic venous system, including the hepatic vein. [7] [8] As pulmonary heart disease progresses, most individuals will develop symptoms like: [1] Shortness of breath; Wheezing ...

  5. Hypoxemia - Wikipedia

    en.wikipedia.org/wiki/Hypoxemia

    Tissue hypoxia refers to low levels of oxygen in the tissues of the body and the term hypoxia is a general term for low levels of oxygen. [2] Hypoxemia is usually caused by pulmonary disease whereas tissue oxygenation requires additionally adequate circulation of blood and perfusion of tissue to meet metabolic demands. [4]

  6. Respiratory failure - Wikipedia

    en.wikipedia.org/wiki/Respiratory_failure

    Respiratory failure is classified as either Type 1 or Type 2, based on whether there is a high carbon dioxide level, and can be acute or chronic. In clinical trials, the definition of respiratory failure usually includes increased respiratory rate, abnormal blood gases (hypoxemia, hypercapnia, or both), and evidence of increased work of breathing.

  7. Respiratory arrest - Wikipedia

    en.wikipedia.org/wiki/Respiratory_arrest

    There is maintenance of a minimum respiratory rate. In the pressure support ventilation, the minimum rate is not set. Instead, all breaths are triggered by the patient. The way that the pressure support ventilation works is by assisting the patient with a constant pressure until the patient's inspiratory flow falls below a threshold.

    “Simple breathing techniques like deep exhalations can help stimulate the parasympathetic nervous system, which will decrease the heart rate.” Breathing in through the nose for the count of 4 ...

    en.wikipedia.org/wiki/Hs_and_Ts

    Acidosis (hydrogen cation excess) is an abnormal pH in the body as a result of lactic acidosis which occurs in prolonged hypoxia and in severe infection, diabetic ketoacidosis, kidney failure causing uremia, or ingestion of toxic agents or overdose of pharmacological agents, such as aspirin and other salicylates, ethanol, ethylene glycol and other alcohols, tricyclic antidepressants, isoniazid ...
