Study Notes
Cardiac Conditions and Devices
- A left ventricular assist device (LVAD) results in an absence of a palpable pulse due to continuous pump flow.
- Return of spontaneous circulation (ROSC) in a cardiac arrest patient requires BVM ventilation and oxygen saturation assessment if unresponsive with irregular breathing.
- Automatic implantable cardiac defibrillators (AICD) differ from external defibrillator vests, which deliver high-energy shocks like an AED.
Legal and Ethical Considerations
- The primary legal risk associated with using an AED is failing to deliver a necessary shock.
Cardiac Function and Health
- Cardiac output increases with both a higher heart rate and stroke volume.
- A common medication for chest pain that prevents blood clots is aspirin.
- Anginal pain typically resolves with rest, distinguishing it from acute myocardial infarction (AMI).
Blood Vessels and Circulation
- Pulmonary veins are responsible for transporting oxygenated blood.
- A hypertensive emergency can manifest through a bounding pulse, severe headache, and dizziness.
- Atherosclerosis is the condition where coronary arteries narrow due to fatty deposits.
Patient Assessment Indicators
- Signs of a dissecting aortic aneurysm can include severe chest pain radiating to the back and significant blood pressure differences between arms.
- Patients in congestive heart failure typically do not exhibit hypotension or flat jugular veins.
Emergency Procedures
- Before using an AED, ensure no one is in contact with the patient.
- Following a "no shock advised" message from an AED, perform CPR for 2 minutes before reassessing.
ECG and Monitoring
- A 12-lead ECG should be done with the patient supine and legs uncrossed.
- Accurate ECG monitoring requires predetermined electrode locations, and each strip must be labeled after monitoring.
Dosages and Administration
- Recommended low-dose aspirin for chest pain is between 162 mg to 324 mg.
- Administer prescribed nitroglycerin tablet or spray sublingually and reassess blood pressure within 5 minutes after administration.
Pediatric Considerations
- If treating a child with chest pain, avoid assuming that manual defibrillators are always preferred for infants aged between 1 month and 9 months.
Statistics and General Knowledge
- Approximately 40% of patients experiencing an AMI do not reach the hospital alive.
- Blockage leading to an AMI typically occurs in coronary arteries; however, incidents may also involve pulmonary arteries among other factors.
- Automaticity in cardiac cells allows them to contract spontaneously without a nerve impulse.
