AB - CHAPTER 3 METHODS Pvepmratioii 01 the Apparatu To ensure adequate stability the apparatus is switched on two hours before the examination. The manometer and one pair of stopcocks are carefully cleaned with a detergent (benzalkonium chloride 50 % 2 g; aceton 80 g; spir. conc. 96 % 10 g; aqua dest. ad 400 g) and the manometer with connected stopcocks is then filled with freshly boiled distilled water. Another pair of stopcocks is sterilized by boiling and then connected to the catheter, which has been cold sterilized for 24 hours in a liquid composed of Septin 10 g. sodium phosph. tribas. 50 g, and aqua dest. ad 5000 g. The catheter with three-way stopcocks is immersed in a saline-filled container and the connecting tubes from two bottles containing heparinized saline are each fitted to one of a stopcock. The catheter is prrfused until air bubbles cease to escape from branch the catheter openings. The stopcocks are then closed and the catheter is ready for insertion into the artery. The exclusion of air bubbles from the whole catheter- manometer system is of fundamental practical importance in this procedure since even small air bubbles can substantially reduce the frequency response.
