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.
