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 ...
Pulse pressure is calculated as the difference between the systolic blood pressure and the diastolic blood pressure. [3] [4]The systemic pulse pressure is approximately proportional to stroke volume, or the amount of blood ejected from the left ventricle during systole (pump action) and inversely proportional to the compliance (similar to elasticity) of the aorta.
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 ...
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.
The development of new techniques for monitoring is an advanced and developing field in smart medicine, biomedical-aided integrative medicine, alternative medicine, self-tailored preventive medicine and predictive medicine that emphasizes monitoring of comprehensive medical data of patients, people at risk and healthy people using advanced ...
Trend of central venous pressure as a consequence of variations in cardiac output. The three functions indicate the trend in physiological conditions (in the centre), in those of decreased preload (e.g. in hemorrhage , bottom curve) and in those of increased preload (e.g. following transfusion , top curve).
A person's pulse is taken, usually at the radial artery near the wrist, in order to assess for the rhythm and strength of the pulse. The blood pressure is taken, using either a manual or automatic sphygmomanometer or using a more invasive measurement from within the artery. Any elevation of the jugular venous pulse is noted.
The PAT signal is a form of pulse wave amplitude measured by incorporating both a unified pressure field and a specific isosbestic wavelength.Applying a uniform pressure field around the measured surface releases arterial wall motion restriction, magnifies the dynamic range of the recorded signal, and prevents the distention of the veins distal to the site of pressure application.
