Overview
ISO 18778:2022 specifies the basic safety and essential performance requirements for infant cardiorespiratory monitors - medical electrical (ME) equipment intended to monitor cardiorespiratory parameters in sleeping or resting children under three years of age. The standard covers devices designed for home healthcare, lay operators, and transit‑operable use, and also applies to manufacturer‑intended accessories (for example probes, cables, and distributed alarm systems) when those accessories can affect safety or performance.
Key topics and technical requirements
ISO 18778:2022 addresses a full product lifecycle of infant cardiorespiratory monitors with focus areas including:
- Scope and classification of ME equipment and ME systems for infant monitoring.
- Essential performance and single‑fault safety considerations to ensure reliable operation under fault conditions.
- Accuracy requirements for direct respiration monitoring and indirect heart‑rate monitoring (including pulse oximetry inputs) and requirements for apnoeic patient alarm conditions and sensor fault detection.
- Testing and validation protocols, including clinical performance evaluation and a sequence of tests.
- Identification, marking and documentation: labelling, operating instructions for lay operators and healthcare professionals, warnings, start‑up procedures, and maintenance guidance.
- Protection against hazards: electrical, mechanical, thermal and radiation hazards; patient leakage current measurement guidance; biocompatibility; and precautions for cleaning, disinfection and sterilization.
- Alarm systems: design, volume/characteristics, logging and inactivation behavior appropriate for infant monitoring.
- Usability and training: human factors for lay operators and professional users to reduce use errors.
- Electromagnetic compatibility (EMC) and electromagnetic disturbance testing.
- Programmable electrical medical systems (PEMS) lifecycle and documentation requirements.
- Functional connections: requirements for integration with electronic health records and distributed alarm systems.
Practical applications - who uses this standard
ISO 18778:2022 is used by:
- Manufacturers and designers of infant cardiorespiratory monitors and accessory components to shape product specifications, risk management and design verification.
- Test laboratories and certification bodies to develop compliance test protocols and assess essential performance and safety.
- Regulators and procurement teams evaluating device safety, labeling and intended use in home healthcare.
- Clinicians, home healthcare providers and caregivers for understanding device capabilities, alarms and safe operation guidance.
Related standards
ISO 18778:2022 complements other international standards for medical electrical equipment and home healthcare devices (standards addressing safety, EMC, usability and device lifecycle documentation) and should be used alongside applicable regional regulatory requirements when certifying infant monitoring devices.
