pulsus paradoxus

Pulsus paradoxus is a medical sign where the strength of a person’s pulse weakens or disappears during inhalation (breathing in) and becomes stronger during exhalation (breathing out). Normally, the pulse remains fairly steady. This change can indicate increased pressure around the heart or lungs, often seen in conditions like cardiac tamponade or severe asthma. Essentially, it reflects abnormal pressure variations affecting how the heart fills and pumps blood, and it helps healthcare providers diagnose underlying issues affecting breathing and circulation.
