Context: The aim of this study was to determine if the AED can be operated correctly on board of rigid inflatable rescue boats (RIBs), and if downloading of data for quality control was possible.

Methods: Six AEDs were tested for their reliability, robustness and stability. Data were collected on three different types of RIBs (Table 1), in a harbour and at sea (Figure 1). Each AED was connected to a volunteer and a manikin simulating VF. Data from the AED were continuously collected.

Results: At the rescue boat type Atlantic, each AED became wet; no AED had a technical problem. When connected to the volunteer, the ECGs delivered by all AEDs showed a regular sinus rhythm. When connected to a manikin in VF, all AEDs were able to recognise VF and to provide a shock. There were differences in the time between first analysis and the shock. The voice prompt of one AED Plus was ‘understandable’, while the other AEDs were ‘difficult to understand’.

Downloading of data was not possible for three AEDs. We had a problem with the infrared connection, which means that evaluation and quality control afterwards may be difficult.

Discussion/Implications: The use of AEDs on RIBs during patient transport over calm water is possible and effective. The AED should have a screen for visual instruction, because the difficulty to understand spoken instruction during action at sea, and better features to download data.

Learning Outcomes
  1. All tested AEDs can be used on RIBs during their duty in nautical environment.
  2. All AEDs can recognize normal rhythm and rhythm disorder in aquatic environment.
  3. Organizations that consider the use of AEDs have to be aware that medical quality assurance may not be possible due the lack of the possibility for some AEDs to download data easy.
