Respiratory arrest is a serious medical condition caused by apnea or respiratory dysfunction severe enough that it will not sustain the body (such as agonal breathing). Prolonged apnea refers to a patient who has stopped breathing for a long period of time. If the heart muscle contraction is intact, the condition is known as respiratory arrest.
Prevention of herpes viruses in immunocompromised people (such as people undergoing cancer chemotherapy) [17] It has not been found to be effective against Epstein–Barr virus and its associated infectious mononucleosis. [18] Aciclovir risks causing resistance to antiviral agents, and in 1% to 10% of cases can cause unpleasant side effects. [19]
Valaciclovir, also spelled valacyclovir, is an antiviral medication used to treat outbreaks of herpes simplex or herpes zoster (shingles). [2] It is also used to prevent cytomegalovirus following a kidney transplant in high risk cases. [2]
Hypoxic breathing gas mixtures in this context are those which will not reliably maintain consciousness at sea level pressure. [ 71 ] 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.
Clinical death is the medical term for cessation of blood circulation and breathing, the two criteria necessary to sustain the lives of human beings and of many other organisms. [1] It occurs when the heart stops beating in a regular rhythm, a condition called cardiac arrest .
In people with a confirmed pulmonary embolism as the cause of arrest, thrombolytics may be of benefit. [122] [88] Evidence for use of naloxone in those with cardiac arrest due to opioids is unclear, but it may still be used. [88] In people with cardiac arrest due to a local anesthetic, lipid emulsion may be used. [88]
Depending on how blocked the airways are , there may or may not be a flow of gas between the lungs and the environment. If there is sufficient flow, gas exchange within the lungs and cellular respiration would not be severely affected. Voluntarily doing this is called holding one's breath. Apnea may first be diagnosed in childhood, and it is ...
Shortness of breath (SOB), known as dyspnea (in AmE) or dyspnoea (in BrE), is an uncomfortable feeling of not being able to breathe well enough. The American Thoracic Society defines it as "a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity", and recommends evaluating dyspnea by assessing the intensity of its distinct ...
