Omron U22 Particle Size, Medication Container Capacity, Sound, Nebulisation rate, Aerosol Output

Technical data

The particle size is measured according to the provisions of the EN13544-1:2007 “Respiratory therapy equipment - Part 1: Nebulising systems and their components”, Annex CC.3 using the multistage cascade impactor method.

Particle Size:	*MMAD 4.2 µm
	MMAD = Mass Median Aerodynamic Diameter
Medication Container Capacity:	7 ml maximum
Sound:	Less than 20 dB
Nebulisation rate:	**Greater than 0.25 ml/min (by weight loss)
Aerosol Output:	*0.69 ml (2ml, 1%NaF)
Aerosol Output Rate:	*0.087 ml/min (2ml, 1%NaF)

Notes:

•The distribution of particle size and aerosol output are measured with 2.5% NaF solution. The particle size distribution and aerosol output may vary by combination of product, medication and ambient conditions such as temperature, humidity and atmospheric pressure.

•Performance may vary with drugs such as suspensions or high viscosity. See drug supplier’s data sheet for further details.

*Independently measured at SolAero Ltd., Canada, Dr. John Dennis, according to EN13544-1:2007.

**The Nebulisation rate is measured with saline 0.9% solution at 23°C and can vary with medication and

ambient conditions.
