We developed an algorithm for processing networked vital signs (VS) to remotely identify in real-time when a patient enters and leaves a given operating room (OR). The algorithm addresses two types of mismatches between OR occupancy and VS: a patient is in the OR but no VS are available (e.g., patient is being hooked up), and no patient is in the OR but(More)
OBJECTIVE To investigate the relationship between oxygenation and short-term outcomes in patients with traumatic brain injury (TBI). DESIGN Logistic regression analysis was used to determine whether average high (>200 mm Hg) or low (<100 mm Hg) PaO2 levels within the first 24 hours of hospital admission correlated with patient outcomes relative to(More)
BACKGROUND Vital signs, particularly blood pressure, are often manipulated to maximize perfusion and optimize recovery from severe traumatic brain injury (sTBI). We investigated the utility of automated continuously recorded vital signs to predict outcomes after sTBI. METHODS Sixty patients with head Abbreviated Injury Scale score ≥ 3, age >14 years,(More)
OBJECTIVE Patients with ischemic stroke treated with tissue plasminogen activator (rt-PA) have better outcomes when treated closer to the time of symptom onset and within the 3-hour window. We previously demonstrated the clinical use of TeleBAT, a mobile telemedicine system for stroke. We tested the impact of that system on time to treatment for patients(More)
BACKGROUND AND PURPOSE Telemedicine is emerging as a potential timesaving, efficient means for evaluating patients experiencing acute stroke. In areas where local stroke care specialists are not available, telemedicine can link an emergency department physician with a specialist in a stroke treatment center. This consultation provides an opportunity for(More)
Natural killer (NK) cells were enumerated by three-color immunofluorescence in 255 uninfected and 399 human immunodeficiency virus-infected adults. Several dramatic alterations were observed. First, the median number and percentage of CD16+CD56+ NK cells, the subset that comprises > 90% of the NK cells in healthy adults, were severely decreased (median,(More)
Trauma Triage errors are frequent and costly. What happens in pre-hospital care remains anecdotal because of the dual responsibility of treatment (resuscitation and stabilization) and documentation in a time-critical environment. Continuous pre-hospital vital signs waveforms and numerical trends were automatically collected in our study. Abnormalities of(More)
BACKGROUND Management strategies after severe traumatic brain injury (TBI) target prevention and treatment of intracranial hypertension (ICH) and cerebral hypoperfusion (CH). We have previously established that continuous automated recordings of vital signs (VS) are more highly correlated with outcome than manual end-hour recordings. One potential benefit(More)
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 data were recorded for direct admission trauma patients with(More)
