Potential impact of electromagnetic
disturbances
The loss or degradation of the following clinical functions due to
electromagnetic disturbances could result in compromised patient safety:
• Accuracy of ventilation control
• Accuracy of monitoring of airway pressure, expired volume and FiO2
• Therapy alarms.
Detection of this degradation could be observed by the following device
behaviour:
• Erratic ventilation delivery
• Rapid fluctuations in monitored parameters
• False activation of therapy or technical alarms (eg, System Fault or Battery
comms lost alarms)
Medical-Portable Electronic Devices (M-PED) that meet the Federal
Aviation Administration (FAA) requirements of RTCA/DO-160 can be used
during all phases of air travel without further testing or approval by the
airline operator.
ResMed confirms that the Astral meets the Federal Aviation Administration
(FAA) requirements (RTCA/DO-160, section 21, category M) for all phases
of air travel.
