摘要:

The development of peritoneal dialysis in its two main forms, intermittent peritoneal dialysis (IPD) and continuous ambulatory peritoneal dialysis (CAPD) is described. The application, results, complications and the choice of patients are compared for IPD and CAPD, and future developments in this field discussed.

摘要:

The routine clinical use of pulsatility index (PI) in the quantitative assessment of Doppler blood velocity/time waveforms, was assessed in normals and in patients with leg ischaemia. Two thousand and five hundred common femoral artery waveforms were studied in 57 subjects (38 males, 19 females). PI values showed a mean variability of 17% in subjects in normal sinus rhythm (NSR) (range 4.1–13.2). In 17 patients in atrial fibrillation (AF) but with no clinical arterial disease, PI varied 26%. Variability was reduced, using a ten beat average, to 7.5% in NSR and 9% in AF.Rise in PI correlated well with increase in peripheral resistance (R = 0.82) but PI was poorly related to arterial stiffness (R = 0.50). Although PI was able to identify patients with proximal arterial narrowing it was unable to distinguish the severity of disease as assessed arteriographically by minimum diameters (R = 0.30).From our observations we conclude that while PI has an established place in the assessment of peripheral arterial disease it must be applied with caution and averaging from ten heart beats is an essential manoeuvre. PI may prove to be a more reliable index for assessing distal rather than proximal disease.

摘要:

A television-computer system is described which scans sets of macro-colonies on agar plates to determine sensitivity of bacteria to selected antibiotics. Decisions are based on a single reflectance measurement within the macro-colony. Results are given of a comparative trial between the machine and six experienced human observers. No significant difference of performance was found, and the machine offers advantages when performing large numbers of tests.

摘要:

This paper describes the performance of a low cost injector which can deliver a constant stream of gas at discrete flow rates up to 21 l/min. The injector has many applications including the preparation of gas mixtures on-site in the laboratory and the injection of a constant known flow of tracer gas for the measurement of minute ventilation.

摘要:

A general purpose add-on filter designed for the rejection of noise and artefact accompanying slowly varying physiological signals is described. The circuit has particular application in the filtration of monophasic artefact caused by movement in a radiotelemetry system for the measurement of skin surface temperature.
