While small amounts of air are usually harmless, it's estimated that more than 5 ml/kg of air introduced into the venous system is generally needed to cause symptoms. However, complications can occur with even 20 ml of air.
Here's a breakdown:
- Small amounts: Usually broken down in the capillary bed and absorbed without issues.
- > 5 ml/kg: Generally the threshold for producing noticeable symptoms.
- 20 ml or more: Even this amount can potentially lead to complications.
| Air Volume | Potential Effect |
|---|---|
| Small amount | Usually harmless |
| > 5 ml/kg | May cause symptoms |
| 20 ml + | Potential for complications |
