4.7  ADDITIONAL CONSIDERATIONS 

4.7.1  Low Cylinder Contents. A situation may arise where the Oxygen in the cylinder may reach a 

very low level with or without the operator being aware of the fact. The pressure therefore 

becomes too low to operate the 

microVENT

. The pressure this occurs at is dependent on the 

individual pressure regulator characteristics but should not occur above 8 Bar (112.p.s.i.) 

indicated cylinder pressure when using a quality regulator. 

4.7.2  Cylinder Replacement Pressure. The cylinder replacement pressure is normally indicated on 

the regulator pressure gauge. Many gauges indicate the red refill region beginning at 30 Bar 

(435 p.s.i.) pressure. It is strongly recommended that once the pressure reaches this section 

the cylinder is switched for a fully charged cylinder. 

4.7.3  Immersion in liquids. It is recommended that the 

microVENT

 is not immersed in any liquids at 

any time. However accidental immersion may occur. If this event does happen wipe clean the 

microVENT

 of any detritus picked up from the fluid with a suitable lint free cloth and then allow 

the 

microVENT

 to drain of any liquids. Once all liquids appear to have drained from the body of 

the 

microVENT

 perform functional tests as per section four of this manual.  

 

5  CHAPTER FIVE: SERVICING 

           CAUTION 

           The 

microVENT

® is designed to provide respiratory support in an emergency situation. 

Failure to follow the maintenance and inspection routines properly could result in 
incorrect operation of the Microvent. 

 

5.1  ROUTINE MAINTENANCE  

5.1.1 

To ensure proper operation of the device, regular inspection and checking of the device for 

correct function should be undertaken by a responsible member of staff on at least a monthly 

basis. This check is to ensure that all Components and Accessories are present, the Oxygen 

Cylinder is full and that the 

microVENT

 is in working order.  

5.1.2 

The following recommendations for servicing frequency are:  

5.1.3 

Monthly checks as per the checklist below.  

5.1.4 

Specification checks and preventive maintenance at 12 months. 

5.1.5 

In accordance to the Medical Device Alert MDA/2003/007, the Medical Oxygen Supply Hose is 

required to be replaced on a 5-yearly basis. If there is any doubt in ascertaining the age of the 

oxygen supply hose, please contact B.N.O.S. Meditech Ltd with the oxygen supply hose batch 

number as indicated on the hose.  

5.1.6 

Automatic units (

microVENT

 Classic and Responder) should also be checked and run on a 

weekly basis  

5.1.7 

Details of Service Contracts available can be obtained from BNOS Meditech Ltd.
