Study Notes
Cardiovascular Emergencies Overview
- Key components of cardiovascular emergencies include physical examination, essential assessment maneuvers, common cardiac symptoms, basic life support, and addressing foreign body airway obstruction.
Carotid Pulse Examination
- Inspect the neck for visible carotid pulsations, located medial to the sternocleidomastoid (SCM) muscles.
- Palpate the right carotid artery in the lower third of the neck using index and middle fingers/left thumb; avoid carotid sinus pressure to prevent syncope.
- For the left carotid artery, use the right fingers/thumb; never palpate both arteries simultaneously.
Brachial Pulse Examination
- Position the patient's arm with the elbow extended and palm facing up.
- Cup your hand under the elbow or support the forearm for relaxation.
- Palpate the pulse medial to the biceps tendon using the opposite hand's index and middle fingers or thumb.
Stethoscope Use
- Diaphragm: Best for high-pitched sounds like S1, S2, murmurs of aortic/mitral regurgitation, and pericardial friction rubs. Use light pressure for effective listening.
- Bell: Sensitive to low-pitched sounds such as S3, S4, and mitral stenosis murmurs; apply it lightly for an air seal to avoid losing sound detection.
Blood Pressure Measurement
- A sphygmomanometer consists of an inflatable cuff, measuring device, and a stethoscope for listening to Korotkoff sounds.
- Blood pressure is the force exerted by blood on artery walls, influenced by heart contraction strength and artery wall characteristics.
- Blood pressure readings are recorded as systolic over diastolic (e.g., 120/80 mmHg), where systolic pressure occurs during heartbeats and diastolic pressure occurs during heart refilling.
Importance of Monitoring Blood Pressure
- High blood pressure stresses the heart and blood vessels, increasing the risk of cardiovascular damage.
- Regular measurement and management are crucial in preventing adverse health outcomes.
