The Pulse Oximeter Plethysmographic Waveform Reflects Changes That Occur during the Respiratory Cycle
Many pulse oximetry technologies display a processed and filtered representation of the photoplethysmosgraphic waveform. Each manufacturer uses unique proprietary algorithms to calculate the waveform displayed on the pulse oximeter. Masimo has extracted and processed information from the waveform to create two physiologic indices, perfusion index (PI) and pleth variability index (PVI). PI is ca...

متن کاملPulse oximeter plethysmographic waveform changes in awake, spontaneously breathing, hypovolemic volunteers.
BACKGROUND The primary objective of this study was to determine whether alterations in the pulse oximeter waveform characteristics would track progressive reductions in central blood volume. We also assessed whether changes in the pulse oximeter waveform provide an indication of blood loss in the hemorrhaging patient before changes in standard vital signs. METHODS Pulse oximeter data from fin...
متن کاملTherapy of vasovagal syncope: to prevent the vasovagal reflex or to treat the impending reflex?
Vasovagal syncope (VVS) can be classical (typical) or non-classical (atypical). Classical VVS is diagnosed when precipitating events, such as emotional or orthostatic triggers, are associated with typical autonomic prodromes. If triggers and/or prodromes are not present, VVS is defined as non-classical. The mechanisms of VVS have not been completely elucidated. Our knowledge of the afferent par...
متن کاملPacing for Vasovagal Syncope
Introduction Vasovagal syncope is a common condition, usually associated with a benign prognosis. Most sufferers experience only occasional symptoms, and can be treated with reassurance and lifestyle advice. However, a minority of patients are debilitated by frequent fainting that can infringe on daily living, or even mimic sudden death. This has been termed "malignant" vasovagal syncope becaus...
