Oxygen toxicity; Other names: Oxygen toxicity syndrome, oxygen intoxication, oxygen poisoning: In 1942–43 the UK Government carried out extensive testing for oxygen toxicity in divers. The chamber is pressurised with air to 3.7 bar. The subject in the centre is breathing 100% oxygen from a mask. [1] Specialty
Excessive exposure to oxygen can lead to oxygen toxicity, also known as oxygen toxicity syndrome, oxygen intoxication, and oxygen poisoning.There are two main ways in which oxygen toxicity can occur: exposure to significantly elevated partial pressures of oxygen for a short period of time (acute oxygen toxicity), or exposure to more modest elevations in oxygen partial pressures but for a ...
Methods to decrease surgical site infections in spine surgery include the application of antiseptic skin preparation (a.g. Chlorhexidine gluconate in alcohol which is twice as effective as any other antiseptic for reducing the risk of infection [9]), judicious use of surgical drains, prophylactic antibiotics, and vancomycin.

Oxygen measurement: Almost all circuits have an alarm in case oxygen delivery to the patient is compromised. The alarm goes off if the fraction of inspired oxygen drops below a set threshold. A circuit disconnect alarm or low pressure alarm indicates failure of the circuit to achieve a given pressure during mechanical ventilation.
Pretreatment includes 100% oxygen, lidocaine, and atropine. 100% oxygen should be administered for 3 to 5 minutes. The time depends on pulse rate, pulmonary function, RBC count, and other metabolic factors. Lidocaine can be given in 1.5 mg/kg IV a few minutes before sedation and paralysis. The purpose of administering lidocaine is to blunt the ...
March 11, 2020: Zachary Sabin, an 11-year-old child, died after being forced to drink almost three liters of water in just four hours by his parents. They thought his urine was too dark, so they made him drink water until he threw up. [26] A 2022 study proposed that martial-arts actor Bruce Lee's death in 1973 was due to water poisoning. [27]
Many people with chronic obstructive pulmonary disease have a low partial pressure of oxygen in the blood and high partial pressure of carbon dioxide.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.
If the cause of the cyanosis is poor oxygen saturation by the lungs, allowing the patient to breathe 100% oxygen will augment the lungs' ability to saturate the blood with oxygen, and the partial pressure of oxygen in the arterial blood will rise (usually above 150 mmHg [3]).
