VAE Critical Audit
Intraoperative Emergency Management
Continuous Monitored Parameters
1. Precordial Doppler
Characteristic "washing machine" or roaring murmur over the heart.
2. Sudden EtCO2 Drop
Sharp decline in exhaled carbon dioxide due to "dead space" air lock.
3. Hemodynamic Stability
Sudden unexplained hypotension or bradycardia.
4. Overt Arrhythmia
Late sign: Right heart failure or "Mill Wheel" murmur without Doppler.
Standardized Triage
The sitting position offers superior exposure for pineal and posterior fossa lesions, necessitating high-fidelity VAE surveillance.
Embolism Sentinel Audit
Input the Doppler, EtCO2, and hemodynamic parameters to determine the VAE severity and associated emergency management actions.
