Unverified92% confidenceDecision RuleTime unknown

公共场所配置AED应选双相波(biphasic)机型而非单相波，双相波用更低能量(150J左右)即可达到与单相波(360J)相当或更好的除颤效果，对心肌损伤更小

Unverified公共场所配置AED应优先选择双相波（Biphasic）机型，双相波在120-200J即可达到单相波360J的除颤效果，对心肌损伤更小、复律成功率更高，目前主流合规机型均为双相波96% similar Unverified双相波（双相截断指数波BTE）除颤技术已成主流，能量输出通常150-360J可调或自动，双相波比早期单相波所需能量更低、心肌损伤更小78% similar Unverified电击能量越高对顽固室颤越有效，但对心肌损伤越大；现代双相波机型采用低能量高效除颤策略，无需追求高能量参数，关键看是否有能量自动递增(如150J-200J-200J)功能67% similar Unverified波长越长（穿透越深）疗效范围越大，但设备成本和安全风险也越高；多数家庭康复只需650nm+808nm双波长组合，追求全波段（如1064nm）性价比低65% similar UnverifiedEMS电脉冲的强度档位越多越好只是营销话术，真正有效的是脉冲频率与波形，15档以上多为同一波形的强度递增，实际常用档位不超过3-4档63% similar
