Capillary pressure is an important factor in the exchange of materials between tissue and bloodstream. In studying this peripheral pressure and its changes the method of continuous recording of Schroeder was used. The method is described. The investigations concerned themselves primarily with the slow waves of the peripheral pressure, the so-called third order waves. The waves present under normal conditions can be divided into passive and active ones according to their relation to the blood pressure. The latter are determined by local changes in arteriolar diameter. They disappear after procaine block of the appropriate sympathetic ganglion. The influence of central factors is demonstrated by means of an experiment during sleep. Local modifications can be achieved primarily through various temperatures. Curves with injection of noradrenaline and adenosine monophosphoric acid show the possibilities of pharmacologic influence on capillary pressure. We believe that the integral capillary pressure should be taken into consideration for completeness in measurements of blood flow.

While measurement protocols emphasize a rest period before taking the measurement, this directive has not been supported by any specific study to date. This analysis aimed...

    Hypotension is type of secondary insult and it is related to poor outcome. The ability to predict adverse hypotensive events, where a patient's arterial blood pressure drops to abnormally low levels, would be of major benefit to the fields of primary and secondary health care.
