Revision E

The following purge procedure must be followed any time a regulator is installed on a tank of 
gas.  It should be done immediately after connecting a regulator to a tank to avoid contaminating 
a tank of gas with the air trapped in the dead space of the regulator in the event someone turns 
on and leaves on the valve on the tank. 
 
1. 

Install and tighten the regulator onto the tank. 

2. Insert 

the 

quick-connect 

on one end of the stainless steel hose into the quick-connect 

fitting on the regulator.  Leave the other end of the stainless steel hose free. 

3. 

Crack open and immediately close the tank valve. 

4. 

Gently press the center tip of the quick-connect on the free end of the stainless steel hose 
against a clean hard surface and allow the pressure to bleed to zero.  A small amount of 
high concentration delivery gas will be released at 50 psig.  Keep the hose away from 
patients and clinicians in order to avoid exposure to the gas. 

5. 

Repeat Step 3 and Step 4 above five times (five complete purge cycles). 

6. 

Connect equipment and open the tank valve as needed. 

 

Any time a regulator is installed onto a cylinder and before each patient use, the 
AeroNOx

 system should be purged. - NO EXCEPTIONS!!

 

 
 
 
 

AeroNOx

 Bagger:  Instructions for use with the AeroNOx

 

(See Diagram # 2.)

 

 

CAUTION!

 

 

 

Oxygen and Nitric Oxide mix in the reservoir bag and stagnant flow will cause NO

2

 to be 

formed.  Turn off NO flow when not actively bagging patient.  Flush the bagger with 
oxygen for a least 20 seconds to completely remove NO and NO

2

 before and after patient 

use. 

 

 

Concentrations of nitrogen dioxide in the reservoir bag may exceed 1 ppm.  Large tidal 
volumes may expose patients to the nitrogen dioxide in the reservoir bag. 

 

 

Flush the bagger with oxygen for at least 20 seconds to completely remove NO and NO

2

 

after any interruption in active patient bagging. 

 

 The 

AeroNOx

 may not be able to detect rapid, short acting fluctuations in the 

concentration of the delivered gas, including nitrogen dioxide.  For this reason, the 
AeroNOx

 Bagger is designed for short-term use only. 

 

 

If a patient requires nitric oxide concentrations other than 20 ppm, a separate system 
capable of providing the required concentration must be available.  

DO NOT USE THE 

AERONOX

 BAGGER TO DELIVER CONCENTRATIONS IN EXCESS OF 20 PPM!

  

The generation of nitrogen dioxide increases rapidly above this concentration. 

 

 

Do not alter the length of the Bagger Gas Supply Tubing as this may cause generation of 
excessive levels of nitrogen dioxide.
