Study Notes
Cardiovascular System
- Angina pectoris is primarily caused by atherosclerosis, which is the narrowing of the coronary arteries, reducing blood flow to the heart muscle.
Nitroglycerin and Heart Workload
- Nitroglycerin helps reduce the workload on the heart by dilating the coronary arteries and peripheral vessels, increasing blood flow and oxygen delivery to the heart muscle.
- This reduces the Heart's Oxygen Demand, relieving the symptoms of angina pectoris.
Dyspnea
- A person experiencing dyspnea typically maintains a characteristic position, sitting upright and leaning forward, in an attempt to relieve respiratory distress.
Flail Chest
- A distinguishing feature of Flail chest is a segment of the chest wall that is detached from the rest of the thoracic cage and moves paradoxically, opposite to the normal breathing motion, due to the fracture of two or more ribs.
