The dead person is always pulse-less. You cannot feel any radial pulse in both fore-arms or any pulse anywhere in the body. The heart pumps blood out into the body through vessels producing a pressure onto their walls. This pressure produces and amplitude in the vessel wall that is felt as a “Pulse”. If the heart is not functioning, no pulse can be felt. However, only pulselessness does not confirm that the patient is dead. In several conditions, pulse may not be recordable. In other words, a working heart may be too weak to produce pulse. Carotid pulses are better to be examined.
No Blood Pressure
No blood pressure can be recorded in both upper limbs or anywhere in a dead person. In a dead person, heart stops working! The heart pumps blood out into the body through vessels producing a pressure onto their walls. This pressure is named as “Blood Pressure”. If the heart is not working, no blood pressure can be recorded. However, only B.P. lessness does not confirm the patient is dead. In several conditions, blood pressure may not be recordable. In other words, a working heart may be too weak to produce enough power to give a recordable blood pressure.

No Heart Sounds
No heart sounds can be heard over the chest of a dead person at least for one minute. Simply, when the heart is dead, no sound will be produced. If you are in doubt, ask to your colleague to hear the patient’s heart (auscultate).
