Does bulk removal hurt with liquid nitrogen?

Description : I have a lump in my ear. On my skin, she removes her for 70 CZK with liquid nitrogen. Do you think it will hurt? I don't know if I should go there.

Last Answer : Definitely go! You never know what the newcomer will do in the future and what will degenerate into. I don't know if it will hurt, but I know it takes a few seconds and you will last and survive those few seconds. Definitely yes!

Which of the following statement(s) is/are true concerning the multiorgan failure syndrome (MOFS)? a. Changes in the splanchnic and pulmonary microcirculation are critical to the development of MOFS b. Tissue fixed microphages, including the liver Kupffer cell, have little role in the development of MOFS c. MOFS represents systemic consequences of loss of homeostatic control of local inflammation and microcirculatory hypoperfusion d. The nature of MOFS is highly dependent upon the etiology of the underlying problem

(4) less soluble in blood than nitrogen at high pressure Explanation: Deep-sea divers have their oxygen supply mixed with helium in order to avoid the toxic nature of oxygen under extreme pressures. The Helium atom is much smaller than the Nitrogen molecule, has a smaller electron cloud and is less polarizable. It, therefore is less soluble in blood than nitrogen and prevents the formation of nitrogen bubbles in blood which blocks blood flow as the diver comes to the surface of the sea from underwater.
