In medicine, the pulse is the rhythmic throbbing of each artery in response to the cardiac cycle (heartbeat). [1] The pulse may be palpated in any place that allows an artery to be compressed near the surface of the body, such as at the neck (carotid artery), wrist (radial artery or ulnar artery), at the groin (femoral artery), behind the knee (popliteal artery), near the ankle joint ...
A pulse pressure is considered abnormally low if it is less than 25% of the systolic value. [2] If the pulse pressure is extremely low, i.e. 25 mmHg or less, it may indicate low stroke volume, as in congestive heart failure. [3] The most common cause of a low (narrow) pulse pressure is a drop in left ventricular stroke volume.
Central venous pressure (CVP) is the blood pressure in the venae cavae, near the right atrium of the heart. CVP reflects the amount of blood returning to the heart and the ability of the heart to pump the blood back into the arterial system.
There are four primary vital signs which are standard in most medical settings: [7] Body temperature; Heart rate or Pulse; Respiratory rate; Blood pressure; The equipment needed is a thermometer, a sphygmomanometer, and a watch. [8] Although a pulse can be taken by hand, a stethoscope may be required for a clinician to take a patient's apical ...
Signs of return of spontaneous circulation include breathing, coughing, or movement and a palpable pulse or a measurable blood pressure. Someone is considered to have sustained return of spontaneous circulation when circulation persists and cardiopulmonary resuscitation has ceased for at least 20 consecutive minutes.
As its name suggests, your resting heart rate, or pulse, is the number of times your heart beats per minute when you’re at rest. (Not to be confused with blood pressure , the force with which ...
Pulse checks, both centrally and peripherally, assessing rate (normally 60-80 beats per minute in a resting adult), regularity, strength, and equality between different pulses; Blood pressure measurements can be taken to assess for signs of shock; Auscultation of the heart can be undertaken by medical professionals
Medical personnel checking the carotid pulse of a simulated patient. Cardiac arrest is synonymous with clinical death. [17] The physical examination to diagnose cardiac arrest focuses on the absence of a pulse. [30] In many cases, lack of a central pulse (carotid arteries or subclavian arteries) is the gold standard.
