Pulmonary edema cardiac arrest due to hypoxia. It is a cardinal feature of congestive heart failure. The term edema is from the Greek (oídēma, "swelling"), from οἰδέω (oidéō, "I swell"). The most common symptom of pulmonary edema is difficulty breathing, but may include other symptoms such as coughing up blood (classically seen as pink, frothy sputum), excessive sweating, anxiety, and pale skin. Shortness of breath can manifest as orthopnea (inability to lie down flat due to breathlessness) and/or paroxysmal nocturnal dyspnea (episodes of severe sudden breathlessness at night). These are common presenting symptoms of chronic pulmonary edema due to left ventricular failure.
Tissue bank and tissue are acceptable organs for donation. A Willed Body Donation program is a program that allows people to donate their bodies after death. Most U.S. tissue bank companies get their supply of cadaver tissue through Willed Body Donation programs run by the tissue bank itself. These programs then charge their customers (mainly medical instrument companies) for services associated with preparation of the cadaver tissue ("e.g." transportation, refrigeration, and recovery) rather than charging money for the donated tissue itself, though it is not illegal to do so for non-transplant and or research organizations per the Uniform Anatomical Gift Act as
