Advantages
- Relatively easy to insert and use
- Allows continuous monitoring
- Lower risk of infection than EVD (absence of fluid coupled system)
- Lower risk of haemorrhagic complications than EVD
- Accuracy generally considered comparable with that of EVD
Disadvantages
- Prone to drift (though don’t require routine replacement)
- Cannot be recalibrated once sited
- May only represent local rather than global pressures
- Does not allow for CSF drainage
