Background
Power outages pose meaningful risk for patients on APD, particularly as outage duration increases. Loss of power can halt traditional cyclers, interrupting therapy and preventing completion of prescribed exchanges. Between 2018–2020, >70% of US counties experienced at least 1 outage lasting 8+ hours with shorter outages occurring even more commonly. Outages are greater in low- & middle-income countries. Unlike conventional APD cyclers, the Archimedes APD system has a battery that continues to deliver therapy for a prolonged period of time despite not being plugged into a power source. For safe delivery, Archimedes™ requires dialysate temperatures of >25°C. This allows for both ambulation with the device and continued treatment delivery during power outage. This study compared battery performance of Simergent's Archimedes™ APD system with the specifications of conventional APD cyclers while not connected to a power source.
Methods
Following completion of full charging of 3 Archimedes systems' batteries, the APD cycler initiated a 12-hour PD therapy with eight 2L fill cycles and 65 minute dwell times. Simultaneously, the cycler was disconnected from power. The cycler was observed as to how much of the programmed therapy it was able to complete, where either the battery was depleted or the bag temperature reached the minimum threshold of <25°C. Two scenarios were conducted, with complete recharging between scenarios:
1) Room temperature (21°C)
2) Room temperature >25°C (28°C)
Published specifications of conventional APD cyclers available in the United States were compared.
Results
In testing, 3 Archimedes systems continued delivering therapy for an average of 9h 49m before battery depletion in a warm room and 5h27m at 21°C. During power loss, HomeChoice Claria & Liberty cyclers specify that they stop delivering therapy and resume treatment if power returns within 2 & 8 hours, respectively. The Amia cycler can continue for up to 100 minutes of dwell time & 20 minutes of drain time before stopping.
Conclusion
Archimedes is the only cycler that allows multiple fills, dwells, and drains while operating on battery power. This enables continued therapy delivery for an extended time during power outages. It also allows for ambulation during treatment delivery without an external power source, particularly when the prescribed therapy time exceeds their periods of sleep.
