Study Notes
Cardiac Emergencies and Interventions
- Administer up to 324 mg of baby aspirin for patients with acute chest pain.
- Assess respirations for adequacy in patients presenting with chest pain.
- Utilize nitroglycerin if patients have prescribed medication; monitor blood pressure after administration.
- Initiate high-flow oxygen for patients with chest pressure and seek medical advice if they lack prescribed medications.
Aortic Health and Cardiac Devices
- A dissecting aortic aneurysm results from separation of the inner layers of the aorta.
- External defibrillator vests must not interfere with CPR; batteries should be removed before vest removal.
- Patients with a left ventricular assist device (LVAD) often have a history of acute myocardial infarction.
Physiology of Chest Pain and Cardiac Function
- Chest pain in atherosclerotic heart disease stems from narrowed coronary arteries unable to meet increased blood flow demands.
- Angina pectoris manifests when myocardial oxygen demand exceeds supply.
- Deoxygenated blood returns to the right atrium from the body, essential for blood circulation.
AED and Cardiac Arrest Protocols
- After an AED shock, immediate resumption of CPR is critical.
- Prior to using an AED, ensure the chest is dry to facilitate effective pad adhesion and shock delivery.
- Risk factors for acute myocardial infarction (AMI) include family history, which is non-modifiable.
Hypertensive Emergencies and Heart Function Monitoring
- Chronic hypertension can obscure signs of hypertensive emergencies in patients.
- The sinoatrial node is responsible for generating electrical impulses in the heart, regulating heart rhythm.
- Malfunctioning cardiac pacemakers may present with symptoms including heart rates less than 60 beats/min, syncope, or dizziness.
Pediatric and Adult Cardiac Care
- Use pediatric pads and energy-reducing devices when applying an AED on children aged 1 month to 8 years.
- When obtaining a 12-lead ECG, "LL" and "RL" electrodes are placed on the thighs or ankles.
- Dependent edema is a common sign of right-sided heart failure, indicating fluid retention.
CPR and Immediate Response
- Initiate high-quality CPR immediately in cases of unresponsive, apneic, and pulseless individuals; follow with AED application as soon as possible.
- Cardiac arrest in adults requires rapid assessment and intervention to prevent delays in life-saving measures.
