Q: Patients with severe metabolic acidosis may not be able to tolerate Rapid Sequence Intubation (RSI). What is the exact etiology behind it?
Answer: Patients with severe Metabolic acidosis can deteriorate within seconds, even with a very short apnea episode during RSI. Apnea abruptly halts the compensatory elimination of carbon dioxide, leading to hemodynamic collapse, hard to salvage.
