Photoplethysmographic signals to predict the success of lumbar sympathetic blockade for lower extremity pain.

Park SY1, Baek HJ2, Park KS2, Kim YC3.
The Journal of international medical research.J Int Med Res.2014 Jun 4. pii: 0300060514532619. [Epub ahead of print]
OBJECTIVE: A prospective, observational study to investigate how photoplethysmography (PPG) signals change during lumbar sympathetic blockade (LSB), and whether these changes can predict sympathetically mediated pain (SMP).METHODS: Patients with unilateral lower extremity pain and self-reported cold

Toe photoplethysmographic monitor, a promising noninvasive technique for tracking systolic blood pressure trends beat-to-beat.

Blood pressure monitoring.Blood Press Monit.2014 Jun 2. [Epub ahead of print]
The call for early detection of hypotension creates a heavy demand for new methods that can monitor trends in blood pressure (BP) levels continuously and noninvasively. Photoplethysmography (PPG) is widely used in hemodynamic analysis. We assessed the feasibility of toe PPG in tracing BP trends usin

Automated prediction of early blood transfusion and mortality in trauma patients.

Mackenzie CF1, Wang Y, Hu PF, Chen SY, Chen HH, Hagegeorge G, Stansbury LG, Shackelford S; ONPOINT Study Group.
The journal of trauma and acute care surgery.J Trauma Acute Care Surg.2014 Jun;76(6):1379-85. doi: 10.1097/TA.0000000000000235.
BACKGROUND: Prediction of blood transfusion needs and mortality for trauma patients in near real time is an unrealized goal. We hypothesized that analysis of pulse oximeter signals could predict blood transfusion and mortality as accurately as conventional vital signs (VSs).METHODS: Continuous VS da

… Photoplethysmographic estimation for blood pressure is proposed for a minimal invasive monitoring. … The algorism is to estimate systolic and diastolic pressures based on a correlation to photoplethysmographic information, calibrated with the oscillometric pressures. …
