ABSTRACT:
A device and method are disclosed for electronically measuring the degree of pulsus paradoxus in a patient from a single patient data source. The single data source may be any device that outputs a waveform indicative of patient pulsatile cardiovascular behavior such as an optical plethysmograph, a pulse oximeter, or a blood pressure monitor. The invention is useful for rapidly assessing the status of a patient in acute respiratory distress for the purpose of objectively determining the severity of their condition.
