2. Oxygen toxicity - Wikipedia

   en.wikipedia.org/wiki/Oxygen_toxicity

   Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen (O 2) at increased partial pressures.Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs, and eyes.

3. Effect of oxygen on chronic obstructive pulmonary disease

   en.wikipedia.org/wiki/Effect_of_oxygen_on...

   Treatment with supplemental oxygen may improve their well-being; alternatively, in some this can lead to the adverse effect of elevating the carbon dioxide content in the blood (hypercapnia) to levels that may become toxic. [3] [4] With normal lung function, a stimulation to take another breath occurs when a patient has a slight rise in PaCO 2.

4. Hyperoxia - Wikipedia

   en.wikipedia.org/wiki/Hyperoxia

   Partial pressures of inhaled oxygen exceeding 0.6 bar (FIO2 >0.6 at normal atmospheric pressure), administered for extended periods in the order of days, are toxic to the lungs. This is known as low-pressure oxygen poisoning, pulmonary toxicity, or the Lorrain Smith effect.

   A recent study found that smoking an e-cigarette decreased the amount of oxygen being taken in by the lungs, regardless of whether it contained nicotine

   In effect, ARDS impairs the lungs' ability to exchange oxygen and carbon dioxide. [1] Adult diagnosis is based on a PaO 2 /FiO 2 ratio (ratio of partial pressure arterial oxygen and fraction of inspired oxygen) of less than 300 mm Hg despite a positive end-expiratory pressure (PEEP) of more than 5 cm H 2 O. [ 1 ] Cardiogenic pulmonary edema ...

7. Hypoxic pulmonary vasoconstriction - Wikipedia

   en.wikipedia.org/wiki/Hypoxic_pulmonary...

   For this reason, some climbers carry supplemental oxygen to prevent hypoxia, edema, and HAPE. The standard drug treatment of dexamethasone does not alter the hypoxia or the consequent vasoconstriction, but stimulates fluid reabsorption in the lungs to reverse the edema. Additionally, several studies on native populations remaining at high ...
