When it can happen? Needle in side a vessel/ liver Exposed vascular area Argon plasma coagulationHow to recognize? Hypotension and hypoxia Sudden drop in ETco2 Mill wheel murmurHow to manage? Stop pneumoperitoneum and vent it out Head down and left lateral position Aspiration of air through central line
