Operating Instructions 

 

6.1  Installation 

 

Pre-Installation Considerations: 

The GeVentor is designed to be either floor-standing or wall mounted. The GeVentor can be mounted vertically on a pipe stand, 
at an angle or horizontally on a flat surface. A risk assessment associated with the positioning of the GeVentor installation is to be 
determined by the intensive care clinician.  

 

Inspect the GeVentor for any damage that may have occurred during transportation and handling before installation.  

 
 

 

DANGER 

Parts and/or components that have been damaged 
or  tampered  with  during  shipping  are  not  to  be 
used. 

 

 

 

Installation Procedure: 

The following procedure is recommended (refer to the diagram below for components): 

 

1.

 

Remove GeVentor from packaging, outside of the ICU. 

2.

 

Clean unit as per clinical guidelines. 

3.

 

Install battery isolation fuse in fuse mount on bottom of enclosure. 

4.

 

Securely attach accessories. 

5.

 

Connect air gas supply connection into the air connection port. 

6.

 

Install GeVentor Expiration Valve (on expiration side of the patient circuit) 

7.

 

Connect oxygen gas supply connection into oxygen connection port. 

8.

 

Connect inspiration hose into 22 mm inspiration hose port. 

9.

 

Connect expiration hose into 22 mm expiration hose port after the Bio-filter. 

10.

 

Install the PEEP valve above the GeVentor Expiration Valve. 

11.

 

Plug GeVentor into electrical supply mains power and switch the unit on. 

12.

 

Check if HMI is operational.  

 

 

 
 

 

 
 
 
 
 
 
 
 
 
 
 
 
 
Note: 

The GeVentor’s

 Battery Isolation fuse is stored within the Instructions for Use, contained by a plastic envelope.
