Continuous albuterol has become the standard of care for patients in status asthmaticus. We have previously performed an in-vitro study comparing 4 different brands of continuous nebulizers. We now want to compare the in-vitro with the in-vivo performance of the brand we use. we hypothesize that there will be no difference between in-vivo and in-vitro results.
Condition or disease
There will be no intervention to the patients. Nebulizers will be used as per current policies and procedures. They will only be marked on the outside at the water level every 2 hours for the first 6 hours. Once ready to be discarded will be collected for laboratory testing Once in the laboratory, nebulizers will be weight on a precision scale without liquid, then they will be filled with normal saline to the first mark (6th hour) and re-weight. The nebulizers will be filled to next mark and re-weight until 200 mls. of total volume are achieved. Solution output will be calculated as the weight difference between the 2 hour periods.
