  2. Decompression sickness - Wikipedia

    en.wikipedia.org/wiki/Decompression_sickness

    One of the more frequently used treatment schedules is the US Navy Table 6, which provides hyperbaric oxygen therapy with a maximum pressure equivalent to 60 feet (18 m) of seawater (2.8 bar P O 2) for a total time under pressure of 288 minutes, of which 240 minutes are on oxygen and the balance are air breaks to minimise the possibility of ...

  3. Oxygen saturation (medicine) - Wikipedia

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

    At 1,600 meters' altitude (about one mile high) oxygen saturation should be above 92%. [11] An SaO 2 (arterial oxygen saturation) value below 90% causes hypoxia (which can also be caused by anemia). Hypoxia due to low SaO 2 is indicated by cyanosis, but oxygen saturation does not directly reflect tissue oxygenation. The affinity of hemoglobin ...

  4. Hyperbaric medicine - Wikipedia

    en.wikipedia.org/wiki/Hyperbaric_medicine

    Hyperbaric medicine includes hyperbaric oxygen treatment, which is the medical use of oxygen at greater than atmospheric pressure to increase the availability of oxygen in the body; [8] and therapeutic recompression, which involves increasing the ambient pressure on a person, usually a diver, to treat decompression sickness or an air embolism by reducing the volume and more rapidly eliminating ...

  5. Oxygen saturation - Wikipedia

    en.wikipedia.org/wiki/Oxygen_saturation

    Dissolved oxygen levels required by various species in the Chesapeake Bay (US). In aquatic environments, oxygen saturation is a ratio of the concentration of "dissolved oxygen" (DO, O 2), to the maximum amount of oxygen that will dissolve in that water body, at the temperature and pressure which constitute stable equilibrium conditions.

  6. Acute respiratory distress syndrome - Wikipedia

    en.wikipedia.org/wiki/Acute_respiratory_distress...

    Acute respiratory distress syndrome (ARDS) is a type of respiratory failure characterized by rapid onset of widespread inflammation in the lungs. [1] Symptoms include shortness of breath (dyspnea), rapid breathing (tachypnea), and bluish skin coloration (cyanosis). [ 1 ]

  7. Cerebral hypoxia - Wikipedia

    en.wikipedia.org/wiki/Cerebral_hypoxia

    Cerebral hypoxia is a form of hypoxia (reduced supply of oxygen), specifically involving the brain; when the brain is completely deprived of oxygen, it is called cerebral anoxia. There are four categories of cerebral hypoxia; they are, in order of increasing severity: diffuse cerebral hypoxia (DCH), focal cerebral ischemia , cerebral infarction ...

  8. Pulse oximetry - Wikipedia

    en.wikipedia.org/wiki/Pulse_oximetry

    A pulse oximeter probe applied to a person's finger. A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram that may be further processed into other measurements. [4]

  9. Respiratory failure - Wikipedia

    en.wikipedia.org/wiki/Respiratory_failure

    Type 1 respiratory failure may require oxygen therapy to achieve adequate oxygen saturation. [14] Lack of oxygen response may indicate other modalities such as heated humidified high-flow therapy, continuous positive airway pressure or (if severe) endotracheal intubation and mechanical ventilation. .
