Pulsus paradoxus (PP) is a sign of great diagnostic value in cardiac tamponade. The clinical detection of PP is sometimes nebulous, especially during haemopericardium due to aortic dissection and aortic valve regurgitation, or when large atrial septal defects coexist. The Doppler echocardiographic phenomenon of flow velocity paradox along the great arteries, frequently heralds the appearance of a palpable PP. In cases of tamponade with atrial fibrillation, pulse oximetry is a rational approach for detecting the presence of PP.

D010092 Oximetry The determination of oxygen-hemoglobin saturation of blood either by withdrawing a sample and passing it through a classical photoelectric oximeter or by electrodes attached to some translucent part of the body like finger, earlobe, or skin fold. It includes non-invasive oxygen monitoring by pulse oximetry. Pulse Oximetry,Oximetry, Pulse,Oximetries,Oximetries, Pulse,Pulse Oximetries
