Occurrences of cellulitis may also be associated with the rare condition hidradenitis suppurativa or dissecting cellulitis. [14] The appearance of the skin assists a doctor in determining a diagnosis. A doctor may also suggest blood tests, a wound culture, or other tests to help rule out a blood clot deep in the veins of the legs.
The rapidly diffusing gas is transported into the tissue faster than the slower diffusing gas is transported out of the tissue. [42] This can occur as divers switch from a nitrogen mixture to a helium mixture (diffusivity of helium is 2.65 times faster than nitrogen), [42] or when saturation divers breathing hydreliox switch to a heliox mixture ...
Gas is breathed at ambient pressure, and some of this gas dissolves into the blood and other fluids. Inert gas continues to be taken up until the gas dissolved in the tissues is in a state of equilibrium with the gas in the lungs (see saturation diving), or the ambient pressure is reduced until the inert gases dissolved in the tissues are at a higher concentration than the equilibrium state ...
Anaerobic bacteria can be divided into strict anaerobes that can not grow in the presence of more than 0.5% oxygen and moderate anaerobic bacteria that are able of growing between 2 and 8% oxygen. [1] Anaerobic bacteria usually do not possess catalase, but some can generate superoxide dismutase which protects them from oxygen.

The amount of gas dissolved in a liquid is described by Henry's Law, which indicates that when the pressure of a gas in contact with a liquid is decreased, the amount of that gas dissolved in the liquid will also decrease proportionately. On ascent from a dive, inert gas comes out of solution in a process called "outgassing" or
However, if they have blood in the stool, high fevers, shortness of breath or other unusual symptoms, they should consider consulting a medical professional — since what they have may not be ...
Livedo racemosa or, less commonly, livedo reticularis are symptoms of such thrombosis, which causes blood and pressure to build up in the dermal superficial veins. [8] The oxygen partial pressure in the skin decreases as a result of the blood flow obstruction, triggering a cutaneous response that presents as pruritus with itchy papules and ...
