The scope of this article is to describe the Drass program for training operators and technicians of hyperbaric medical systems.

The activities proposed by Drass are managed according to an ISO 13485 compliant quality system, taking advantage of this standard approach, with benefits for customers, operators and patients.

The management and maintenance of a hyperbaric facility requires a full understanding of the system layout and method of operation to address pre-operation checklists and carry out safety maintenance.
The hyperbaric staff must be qualified, and their qualification must be documented, according to facility policies and applicable regulations.
Drass courses provide operators with an insight into the manufacturer’s perspective, which gives complementary background details for the staff, both in daily use and in troubleshooting, improving the system safety.
This practical knowledge will complement their professional medical training and experience in performing hyperbaric therapies.

The typical profiles of the participants to Drass courses are: 

  • Hyperbaric operators and medical staff 
  • Technical staff and clinical engineers
  • Facility managers who would like to have a deeper understanding of the system


Four good reasons for a training program

Significant risks arise when there is a lack of documented training programs for operational and technical personnel involved in the hyperbaric facility. Four clear examples are:

  1. Use of the system without sufficient knowledge of the physical configuration, with the potential for human error even in a fully functional system.
  2. Unauthorized, incorrect or incomplete maintenance with associated risks to equipment, patients and operators
  3. Competent, but unqualified personnel who, in the event of an accident, cannot prove their competence and can therefore be liable to negligence
  4. As an important financial impact for the facility manager, staff might decide to call for external assistance too frequently, with inconveniences for patients and hospital structure.

Drass proposes itself as the authority for the technical competences of hyperbaric facility staff.


Overview of Drass courses

The training courses follow the different experiences, competences and responsibilities assigned to each member of staff.

A key factor is the level of independence that hyperbaric staff want to reach when performing minor maintenance, to ensure the best continuity of services and minimize the use of external help when not actually needed.

The courses proposed in the Drass training program are:

1. Basic course:

This course provides basic training on the architecture of the plant and its main components and functionalities. Course modules include:

    • System layout review
    • Main subsystems, technologies and architecture
    • Training on basic mode of operations of the subsystems and components
    • Management of system resources
    • Software interfaces
    • Ancillary equipment
    • Drass documentation and info channels

2. Safety course

:This course enables a selected group of operators to qualify for continuous monitoring and safety conditions, including correct firefighting equipment, safety devices, calibration timeframes and other planned maintenance activities. Course modules include:
    • Factory maintenance schedule
    • Training on maintenance documents
    • Safety devices, calibration, check and replacement, theory and practice
    • Analyzer calibration methods and practice, theory and practice
    • Maintenance log
    • Critical spare parts management

3. Failure assessment course

This course allows a select group of operators with technical background, training and qualifying them to perform a basic failure assessment, rather than having to ask for manufacturer intervention. This, therefore, saves on intervention costs and ensures continuity of service. The level of detail of the failure assessment is tailored to the specific configuration of the plant and the policy of facility managers. Course modules include:

    • Troubleshooting principles of subsystems and components with reference to system architecture
    • Failure reporting and tracking
    • Root Cause Analysis: principles and practical examples
    • Training on risk assessment documentation
    • Management of emergencies

4. Periodic requalification: Every 3 years there is a review of qualified operators, with assessment by Drass staff, to refresh knowledge and practical application of the procedures.

The elements of competence provided for each training course are briefly described in document FA50601. Number and profiles of participants are tailored to the relevant training course. Larger systems may involve more participants with different skills.  The table below shows some examples of this scaling:


Typical training programs for different types of systems:

System example Medical Staff Technical Staff Managers Typical Training Program
4-patient small hyperbaric chamber system 2 2  

4x BASE (for the entire staff)


Traditional 10-patient chamber system 2 2 1

5x BASE (for the entire staff)



2X 12 patient chambers with automation system 4 4 2

10x BASE (for the entire staff)




Drass service plans

Facility staff are trained on specific documentation that form the basis for Drass maintenance plans.
The training is carried out using the same documentation that the personnel will handle during worktime.
