Usability-Tests of Mechanical Ventilators: A Systematic Review

Area of Science:

• Medical Device Engineering
• Human Factors Engineering
• Patient Safety

Background:

• Ventilator usability is crucial for safe patient care.
• Existing usability studies on ventilators lack comprehensive functional coverage.
• Regulatory approval requirements for manufacturers are not fully addressed by current usability testing.

Approach:

• Systematic review of existing ventilator usability studies.
• Comparative analysis of study methodologies and procedures.
• Evaluation of usability tasks against ISO standards and manufacturer approval requirements.

Key Points:

• Methodologies and procedures in ventilator usability studies are largely consistent.
• Current studies only assess a portion of the primary operating functions outlined in ISO standards.
• There is a gap between the scope of tested scenarios in usability studies and regulatory requirements.

Conclusions:

• Ventilator usability study designs can be optimized for better patient safety.
• Expanding the scope of tested scenarios in usability studies is recommended.
• Aligning usability testing more closely with ISO norms and approval requirements is necessary for manufacturers.
