Limited resources along the continuum of care often require that equipment used in acute care be adapted to meet patient needs in the long term care environment. The purpose of this study was to evaluate an efficient means for delivering high to medium concentrations of humidified oxygen to tracheostomized residents in skilled nursing facilities. We hypothesized that the GinBaby nebulizer could provide stable and predictable concentrations of oxygen and flow when used with an oxygen concentrator and air compressor.

METHODS:
An Easy Air® compressor set at 20 PSI was used to provide the primary gas source which produced a measured flow of 24 LPM. Seventy-two inches of large bore tubing connected the nebulizer to the tracheostomy mask. A water trap was placed inline at the tubing’s mid point. Invacare 5 ® oxygen concentrators provided the secondary source gas. Prior to connecting the secondary gas inlet tube to the nipple adaptor on the oxygen concentrator a flow verification and analysis procedure confirmed 95% oxygen was provided at 2 LPM. Flow rates greater than 5 LPM were provided by linking two concentrators in tandem with a tee connector. A Mini Ox III ® oxygen analyzer was calibrated and placed inline proximal to the mask. FIO2 were analyzed and recorded at each flow variation from 0.5 to 10 LPM in 0.5 LPM increments after a two-minute stabilization time. The experimental conditions were repeated using six different nebulizer tops from three distinct lots. Total flow was calculated as the sum of flow from the primary and secondary gas sources. Data were analyzed using linear regression analysis. Significance was established at p< 0.05.

RESULTS:Analysis on a multivariate level revealed a statistically significant correlation between flow and FIO2 (p=0.001, R Square = 0.926.



CONCLUSIONS: The use of the GinBaby nebulizer was able to produce stable low to medium concentrations of oxygen. FIO2 can be reliably adjusted by changing the flow on the secondary gas source.
