COMPARISON OF THE LC PLUS AND LC STAR NEBULIZERS USING THE PULMOAIDE, PARI MASTER AND PARI PRONEB TURBO COMPRESSORS.

D. Todd Loffert M.H.S.(Johns Hopkins), and Kim Francis, BS(Virginia Commonwealth University)

Three commercially available compressors were studied using LC PLUS and LC STAR. The nebulizers were operated using an PARI PRONEB TURBO compressor and reanalyzed with a PARI MASTER compressor and Devilbiss Pulmo-Aide compressor. Delivery rate(Ml/Min), percent Particles in the Respirable Range(PRR), and Respirable Particle Delivery Rate(RPDR) were analyzed. All nebulizers were filled with 3.0 ml of saline. PRR was measured by continuous sampling by Laser Particle Analyzer, Malvern MasterSizer X. The nebulizers were sampled at a simulated flow rate of 20 liters per minute.

PARI PRONEB TURBO COMPRESSOR W/LC PLUS Ml/Min average = 0.47 ml/min. PRR average = 68 %. To combine the previous variables RPDR was calculated, = Ml/Min multiplied by PRR RPDR average = 0.32.

PULMO-AIDE COMPRESSOR W/LC PLUS Ml/Min average = 0.43 ml/min. PRR average = 66 %. To combine the previous variables RPDR was calculated, = Ml/Min multiplied by PRR RPDR average = 0.28.

PARI MASTER COMPRESSOR W/LC PLUS Ml/Min average = 0.47 ml/min. PRR average = 69 %. To combine the previous variables RPDR was calculated, = Ml/Min multiplied by PRR RPDR average = 0.32.

PARI PRONEB TURBO COMPRESSOR W/LC STAR Ml/Min average = 0.40 ml/min. PRR average = 74 %. To combine the previous variables RPDR was calculated, = Ml/Min multiplied by PRR RPDR average = 0.29.

PULMO-AIDE COMPRESSOR W/LC STAR Ml/Min average = 0.40 ml/min. PRR average = 72 %. To combine the previous variables RPDR was calculated, = Ml/Min multiplied by PRR RPDR average = 0.28.

PARI MASTER COMPRESSOR W/LC STAR Ml/Min average = 0.47 ml/min. PRR average = 69 %. To combine the previous variables RPDR was calculated, = Ml/Min multiplied by PRR RPDR average = 0.32.
