Is the following statement true or false? the most frequent sign and symptom of a developing pulmonary embolus is tachypnea and
Rainbow [258]

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.
