Glass tubes were drawn on a two stage pipette puller such that tips with 0.5–2.0 μm inner diameters were obtained as confirmed by scanning electron imaging. The pipettes were attached to an air reservoir with a pressure set at 0.5 bar to prevent fluid from entering the tip. They were lowered into 2% hydrofluoric acid by means of a micromanipulator. When air(More)
Dynamic blood pressure was measured in 33 human finger nailfold capillaries after direct cannulation with glass micropipettes by means of a resistance servo-nulling pressure measuring method. ECG, finger pulsations, and respiratory thorax excursions were monitored simultaneously. All recordings exhibited pulsatile oscillations related to the cardiac rhythm.(More)
