Physiologic and Extracorporeal Shock Wave Lithotripsy (ESWL) data were collected before, during and after ESWL from four patient groups employing different anesthetic techniques (epidural anesthesia, general anesthesia with low-volume conventional mechanical ventilation or with unsynchronized high frequency jet ventilation (HFJV) or with HFJV synchronized to the heart rate). The primary goal was to determine if synchronized HFJV had any beneficial effects. A synchronization unit was fabricated that triggered one HFJV breath, per heart beat, delivered 30 milliseconds after the shock wave. This allowed only expiratory motion during shock wave administration. Results were analyzed using one-way analysis of variance, Students t-tests and chi-square tests with significance at p 0.05. Results showed that renal stone excursion was significantly less in HFJV groups and that significantly more patients required re-treatment in non-HFJV groups. No results indicated that synchronizing HFJV had any further benefits than unsynchronized HFJV.

An automated system for quantitative respirator fit testing by negative pressure was evaluated by comparison testing with a computerized aerosol fit test system (Dynatech Frontier Model 260A). The new negative pressure system measures leakage flow while inspiratory pressures are sustained in a respirator facepiece rather than by pressure decay. Four phases of comparison testing were graduated by level of control, ranging from non-subject tests with hypodermic needle leakages to fit tests of 125 Air Force personnel. Throughout the series of tests, negative pressure fit factors were consistently more conservative than aerosol fit factors and showed less variability. Leakage flow rates measured by the negative pressure instrument were highly correlated with leak needle cross-sectional area as predicted by principles of air-flow physics. Comparison of subject and non-subject generated aerosol fit factors indicated significant aerosol losses, possibly due to streamlining and respiratory tract deposition. Negative pressure fit factors were not affected by these subject-related losses.
