Q: What one trick may be used in patient during intubation to avoid rapid hypoxemia during paralytic phase due to neuromuscular blocker use?  

Answer: Pre-oxygenation or de-nitogenation i.e. increasing oxygen reservoir in dead space and tissues via NRM is an integral part of preparation before intubation to avoid hypoxemia during paralytic phase of intubation. In ICU, patients may have very little reserve and may quickly deteriorate if airway cannot be establish within reasonable time. The oxygen reservoir can be supplemented by passive diffusion during the apneic period of Rapid Sequence Intubation (RSI) with the application of oxygen via nasal catheter.
