## 根因

恐慌发作期间过度换气导致二氧化碳过低；没有延长呼气的'深呼吸'可能加重过度换气并增加恐慌；正确技巧需要呼气长于吸气。

## 解决方案

1. ```
   Use the 4-7-8 breathing pattern: inhale through nose for 4 seconds, hold for 7 seconds, exhale through mouth for 8 seconds. This ensures prolonged exhale and activates parasympathetic nervous system.
   ```
2. ```
   Provide a paced breathing audio cue or visual timer: 'Exhale to the count of 6, inhale to the count of 3. Repeat until you feel your shoulders drop.'
   ```
3. ```
   If user cannot do 4-7-8, offer an alternative: 'Breathe out through pursed lips like blowing through a straw for 6 seconds, then let air in naturally for 3 seconds.'
   ```

## 无效尝试

- **** — Users often inhale too deeply and exhale too quickly, perpetuating hyperventilation (75% 失败率)
- **** — Equal inhale/exhale does not correct CO2 balance; exhale must be longer (e.g., 4-7-8 or 4-6 ratio) (60% 失败率)
- **** — Can increase anxiety about breathing itself; user may feel they are 'doing it wrong' (70% 失败率)
