An implantable radio-telemetry device for chronic monitoring of arterial pressure and heart rate in the conscious guinea pig was validated against measurements using an exteriorized, indwelling catheter. There were no significant differences between simultaneous measurements in animals instrumented with both the telemetry system and the conventional(More)
An investigation of postural and chair design impacts upon seat pan interface pressure has been performed in an effort to identify whether differences in posture or chair design result in greater pressure differences. Investigation of postural variables focused on trunk-thigh angle and use of armrests. Twelve ergonomic office chairs were used to assess(More)
The standard gentamicin dosing recommendations for neonates appear to be inappropriate because they fail to consider the influence of neonatal development on gentamicin pharmacokinetics. Recent reports have emphasized that the standard regimens of 2.5 mg/kg q8-12h produce steady-state trough serum concentrations greater than 2 micrograms/ml in up to 91(More)
