Definition:
A weak pulse means you have difficulty feeling a person's pulse (heartbeat). An absent pulse means you cannot detect a pulse at all. See also: CPR
Alternative Names:
Weak pulse; Absent pulse
Considerations:
An absent or weak pulse may affect all or one part of the body. If a pulse cannot be detected by a non-medical professional, it doesn't always mean there is a problem. Sometimes, it can be hard for a non-medical person to detect a pulse in certain areas.
Common Causes:
- Cardiac arrest (lack of an effective heartbeat)
- Improper technique used to feel for the pulse
- Normally weak pulse that is difficult to measure without proper instruments
- Shock
