Gas embolism is a diving disorder experienced by underwater divers who breathe gases at ambient pressure, and can happen in two distinct ways: . Pulmonary barotrauma: Air bubbles can enter the bloodstream as a result of gross trauma to the lining of the lung following a rapid ascent while holding the breath; the air held within the lung expands to the point where the tissues tear (pulmonary ...
In the United States, approximately 550,000 people die each year from heart-related arterial embolism and thrombosis. [1] Approximately 250,000 of these individuals are female, [ 1 ] and approximately 100,000 of all these deaths are considered premature, that is, prior to the age of average life expectancy.
The passage of the catheter may be monitored by dynamic pressure readings from the catheter tip or with the aid of fluoroscopy. The standard pulmonary artery catheter has two lumens (Swan-Ganz) and is equipped with an inflatable balloon at the tip, which facilitates its placement into the pulmonary artery through the flow of blood. The balloon ...
The consequences of this include: acute embolic stroke (from air that passes through a patent foramen ovale), pulmonary edema, and acute right heart failure (from trapped air in the right ventricle) which can lead to cardiogenic shock. [3] The clinical presentation of a venous air embolism may be silent.
Selective pulmonary angiogram revealing significant thrombus (labelled A) causing a central obstruction in the left main pulmonary artery. Pulmonary angiography (or pulmonary arteriography,conventional pulmonary angiography, selective pulmonary angiography) is a medical fluoroscopic procedure used to visualize the pulmonary arteries and much less frequently, the pulmonary veins.
A coronary catheterization is a minimally invasive procedure to access the coronary circulation and blood filled chambers of the heart using a catheter. It is performed for both diagnostic and interventional (treatment) purposes. Coronary catheterization is one of the several cardiology diagnostic tests and procedures.
A myocardial infarction (MI), or heart attack, arises from complete occlusion of a coronary artery. [9] The most frequent cause of MI is the rupturing of an atherosclerotic plaque formed in CAD. Plaque rupture exposes the subendothelial matrix beneath the plaque, initiating thrombus formation within the vasculature. [ 7 ]
The endotracheal tube is a great method for patients who are comatose, have an obstructed airway, or need mechanical ventilation. The endotracheal tube also allows suctioning of the lower respiratory tract. Drugs that can be inserted through the endotracheal tube during cardiac arrest are discouraged.
