URODYNAMICS The term "urodynamics" encompasses any investigation of urinary tract function although it is often used colloquially as a synonym for cystometry. Cystometry, the measurement of bladder pressure, has been the main tool used to show abnormal behaviour of the neurogenic bladder. The earliest reference to a study measuring bladder pressure is commonly given as the paper by Mosso and Pe...

The colloidal osmotic and hydrostatic pressure of chronic subdural hematomas were measured with a manometer in 35 patients. Manometric measurement showed an increase in the hematoma fluid cor responding to 5% of the total hematoma volume. The maximum colloidal osmotic pressure of the hematoma fluid, as measured with a transducer, was 23 ± 12 mmHg (mean ± standard deviation). Hemor...

OBJECTIVE To test the effectiveness of using a cuff pressure relief valve technique to maintain cuff pressure levels within the normal in vitro range (Phase 1) in patients admitted to the intensive care unit (Phase 2) and to test the reproducibility of the technique using different syringes. METHODS In Phase 1, a tracheal tube was inserted into a trachea model. Ten- and 20mL syringes were use...

Duke et al. (1970) developed a mercury manometer and electrode-based controller for a soil water sampler A vacuum applied to soil water percolation samplers permits collecsystem. When coupled with a soil tensiometer, the detion of both macroand matrix-pore liquids. Performance of these field samplers is improved when the extraction vacuum is adjusted in vice automatically adjusted vacuum levels...

The electrical stimulation test to ensure complete ECORDER gastric vagotomy at the time of operation was first described by Burge and Vane in 1958. NBULB No drugs with an anticholinergic action should be used for treatment during the few weeks preceding operation. E ELECTRODE Simple antacids only may be given. Antacids, containing belladonna and drugs of the phenothiazine group, in particular, ...

OBJECTIVE To evaluate the inter-rater reliability of the modified Oxford Grading Scale and the Peritron manometer. DESIGN All participants were evaluated twice, first by one examiner and 30 days later by a second examiner. Measurements of vaginal squeeze pressure were compared with the results from the palpation test. PARTICIPANTS Nineteen women with a mean age of 23.7 years (range 21 to 28...

A direct method is described for measuring the pressure in secondary phloem sieve tubes of oak trees. One end of a 26-gauge stainless steel tube was shaped such that when it penetrated the outer bark and transected a few sieve elements, it was stopped by the xylem so that small openings in the end allowed phloem sap to enter the tube. The other end of the stainless tube (phloem needle) was join...

Abstract Background Increased use of the transorbital approach (TOA) warrants greater understanding risk increased intraocular pressure (IOP) and intraorbital (IORP) due to orbital compression. We aimed investigate changes in IOP IORP response retraction TOA establish a method for continuous measurement intraoperative IORP. Methods assessed nine patients who underwent surgery from January 2017 ...
