What is an indication of a weak pulse?

A faint heartbeat is a clear indication of a weak pulse because it suggests that the heart is not pumping effectively or that there is a reduced amount of blood flow being circulated through the body. This could indicate underlying health issues, such as shock, dehydration, or cardiovascular problems, which impact the heart’s ability to maintain a strong and consistent pulse. Recognizing a faint heartbeat is crucial in a lifeguard's role, as it can guide immediate actions and interventions needed to support the individual's health and safety.

In contrast, a strong heartbeat reflects good cardiac function and adequate blood flow, while a rapid heartbeat, although it may sometimes occur in distress situations, does not necessarily indicate a weak pulse. Pale skin is an external sign that might accompany a weak pulse due to reduced circulation, but it does not directly measure the strength of the heartbeat itself.
