Results in Mathematics, 2019
The authors introduce several types of time-weighted pressures for noncompact and/or noninvariant subsets. The quantities are called time-weighted in the sense that some portion of the measurement is from the past and the remaining portion is from the future. They obtain several characterizations of these time-weighted pressures.

Calculation of pressure half-time
Journal of Veterinary Cardiology, 2008Doppler echocardiography is useful in assessing the severity of obstructive cardiac lesions, such as mitral valve stenosis. The Doppler study can be used to calculate pressure half-time (PHT), which is defined as the time required for the pressure gradient across an obstruction to decrease to half of its maximal value.

Pediatrics, 2007
Therapies for hypotension in very preterm infants are among the most common interventions given to these fragile patients. The proportion of very low birth weight infants who receive potent and potentially toxic interventions varies dramatically from one NICU to another.1 A prospective cohort study of extremely low gestational age newborns (the ELGAN ...

A real-time pressure algorithm
Computers in Biology and Medicine, 1981A digital computer algorithm is described for real-time detection of critical points in the arterial pressure signal. Two externally selected parameters allow for filtering without loss of high frequency components. The accuracy of the algorithm was tested on 1005 cycles.

Pressure-time relationships of pressure-limited neonatal ventilators
Critical Care Medicine, 1983A pressure-limited ventilator (Bourns BP-200, Anaheim, CA) and a simple, manually operated constant flow ventilator were studied using a commercially available infant lung simulator (Bourns LS-130, Anaheim, CA). The characteristics of inspiratory pressure-time relationships during ventilation with these ventilators were analyzed.

The Influence of Orolingual Pressure on the Timing of Pharyngeal Pressure Events
Dysphagia, 2006This study explored the influence of two methods of effortful swallow execution on the timing of pharyngeal pressure events. Participants were asked to either emphasize or minimize tongue-to-palate contact during performance of the maneuver. Twenty healthy participants were evaluated using concurrent submental surface electromyography (sEMG ...
