Automatic noninvasive blood pressure monitors: analog/manual adaptation of Dinamap (TM).

This paper describes some of the features and limitations of the newly-developed, automatic, noninvasive blood pressure monitors. In particular, an analog/manual modification is presented which can be adapted to a variety of such devices. The manual/automatic adaptation of the Critikon Dinamap (TM) blood pressure monitor is specifically described. This modification provides continuous observation of cuff pressure and permits the option of manual cuff inflation and deflation. The analog/manual adaptation is useful in special patient conditions and as a teaching aid.

A neonatal insert adaptor for a capnometer breathe-through cell.

This paper describes a neonatal insert for use with the Hewlett-Packard Model 47210A capnometer airway adaptor. Dead space using this adaptor is 4.2 ml, which compares to 28.4 ml with the standard adaptor system and 4.0 ml with the pediatric Y-piece and endotracheal tube alone. Resistance was evaluated by plotting pressure drop-flow relationships. For oxygen flow rates used of up to seven L/min, the neonatal insert reduced the pressure drop as compared to both the standard adaptor and the pediatric Y-piece and endotracheal tube alone. Pressure drops were not very much larger than calculated theoretical values.
