根因分析

干燥皮肤或电极与皮肤之间的空气间隙会显著增加阻抗，导致烧伤、电击无效以及除颤失败。

English

Dry skin or air gaps between electrode and skin dramatically increase impedance, causing burns, ineffective shock delivery, and failure to defibrillate.

解决方案

  1. Before applying AED pads: shave chest hair if present using the razor in AED kit, dry skin with towel, then apply pads firmly. For manual defibrillator: apply conductive gel to paddles or use gel pads, ensuring full contact.
  2. Use pediatric pads for children under 8 or 25 kg; if unavailable, use adult pads placed anterior-posterior. Code example for impedance check: `if impedance > 150 ohms: reapply pads with gel; else: deliver shock`

无效尝试

常见但无效的做法:

  1. 70% 失败

    User thinks gel is optional because modern AED pads are 'self-adhesive' and pre-gelled; but if skin is dry or hairy, adhesion fails

  2. 65% 失败

    User places pads over clothing or chest hair thinking it will still conduct
