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. Lack of a pulse in the periphery (radial/pedal) may also result from other conditions (e.g. shock) or be the rescuer's misinterpretation.
Ventricular fibrillation (V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart quiver. [2] It is due to disorganized electrical activity. [2] Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. [1]
With cardiac tamponade, jugular veins are distended and typically show a prominent x descent and an absent y descent as opposed to patients with constrictive pericarditis (prominent x and y descent); see Beck's triad. [1] Other possible causes of Kussmaul's sign include: [2] [citation needed] Right ventricular infarction - low ventricular ...
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.
Central Pulse are a New Zealand netball team based in Wellington. Between 2008 and 2016, they played in the ANZ Championship. Since 2017 they have represented Netball Central in the ANZ Premiership. Netball Central is the governing body that represents the Hawke's Bay, Manawatū-Whanganui, Taranaki and Wellington Regions.
Brain failure after clinical death is now known to be due to a complex series of processes called reperfusion injury that occur after blood circulation has been restored, especially processes that interfere with blood circulation during the recovery period. [11] Control of these processes is the subject of ongoing research.
The pulse is the rate at which the heart beats while pumping blood through the arteries, recorded as beats per minute (bpm). [11] It may also be called "heart rate". In addition to providing the heart rate, the pulse should also be evaluated for strength and obvious rhythm abnormalities. [11] The pulse is commonly taken at the wrist (radial ...
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 ...
