Oesophageal pressure measurements in respiratory function tests are commonly performed using a balloon-catheter system. This study investigates the usefulness of catheter-mounted pressure transducers as an alternative to balloon-catheter systems. Calibration related physical properties of the catheter mounted pressure transducers are evaluated in vitro. The behaviour of these transducers in vivo is evaluated in ten volunteers by relating pressures measured in the oesophagus to airway opening pressures and by comparing these relationships with those sequentially obtained by a balloon-catheter system...

Bacterial adhesion to biomaterials is a complex phenomenon involving numerous factors. The ability to reduce urinary catheters infections simply by general hygiene and asepsis is low: an ascending colonization cannot be avoided. This will lead to a clinical infection only if several factors favour the bacterial adhesion or the bacterial coaggregation and the feeding of the bacterial biofilm. Among the many factors involved in bacterial adhesion, we focused in this paper on the physical parameters of surface hydrophobicity of the urinary catheters (Van der Waals and acido-basic forces) and the surface hydrophobicity of the bacteria (BATH and zeta potential)...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
