    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.
    • 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.
