One of the most widespread circumstances of exposure to hypoxic breathing gas is ascent to altitudes where the ambient pressure drops sufficiently to reduce the partial pressure of oxygen to hypoxic levels. [70] Gases with as little as 2% oxygen by volume in a helium diluent are used for deep diving operations.

FILE - A health worker uses a pulse oximeter to check the oxygen saturation level of another after administering COVID-19 vaccine at a hospital in Gauhati, India, Jan. 21, 2021.
Additionally, oxygen in a confined space can be consumed if carbon dioxide scrubbers are used without sufficient attention to supplementing the oxygen which has been consumed. Hypoxic or anoxic breathing gas mixtures, and exposure to a vacuum or other extreme low pressure environment will remove oxygen from the blood in the alveoli.
One of those vital signs is blood oxygen level, and in the hospital, it’s measured with a pulse oximeter. Patients with Covid-19 can sometimes have relatively mild symptoms and seem to be ...

Respiratory failure results from inadequate gas exchange by the respiratory system, meaning that the arterial oxygen, carbon dioxide, or both cannot be kept at normal levels. A drop in the oxygen carried in the blood is known as hypoxemia; a rise in arterial carbon dioxide levels is called hypercapnia. Respiratory failure is classified as ...
Cyanide antidote kit is a widely used method in treating cyanide induced histotoxic hypoxia. It consists of three different parts that are administered one after the other. The three parts are amyl nitrite, sodium nitrite, and sodium thiosulfate. [3] The nitrites act with hemoglobin to form methemoglobin which binds cyanide.
