Experimental Parameters Used During This Study

Exposure No.	Setup	Subject ID	NHP weight (kg)	Duration of exposure
1	Aerosol circuit	NHP-1	4.88	7 minutes 17 seconds
2	Aerosol circuit	NHP-2	5.87	3 minutes 0 second
3	Aerosol circuit	NHP-3	6.78	9 minutes 43 seconds
4	nCPAP circuit	NHP-1	4.98	8 minutes 02 seconds
5	nCPAP circuit	NHP-3	6.78	9 minutes 0 second
