Hypoxia is the state which oxygen is not available in sufficient quantities at a tissue level in the body to maintain the homeostasis. The graph shows the concentration of this condition in Long Island Spund from 91 through 09 in mg/L, showinng in the data that the west area of the region has more cases os hypoxia than the east. Therefore, between the options the one that is a true statement about how well oxygenated to support marine life the region was during that period is the letter C. most years, the water near New York has inadequate oxygen to support marne life.
The statement is True.
Dyspnea has a multi-factorial origin, resulting from bronchospasm or vasospasm, disturbances in pulmonary circulation, immobility or diminished respiratory excursion of the diaphragm, atelectasia and/or pulmonary infarction, anoxia, or impairment of cardiac function.
Dyspnea, chest pain, and cough are the most frequent symptoms of Pulmonary Embolism(PE), while fever, tachycardia, abnormal pulmonary signs, and peripheral vascular collapse are the most common physical findings.
Pulmonary embolism (PE) occurs when a blood clot gets stuck in an artery in the lung, blocking blood flow to part of the lung. Blood clots most often start in the legs and travel up through the right side of the heart and into the lungs. This is called deep vein thrombosis (DVT).
Clot in the lung circulation (pulmonary embolus): Breathlessness is usually sudden and associated with rapid breathing and may be accompanied by chest pain.
