@emswami: Pre-Oxygenation + Washing Out N2 -Don’t start RSI when you’re O2 sat hits 99%. That approach fails to take advantage of N2 washout -Pre-ox washes out N2 replacing with O2 creating an oxygen resevoir -NIV for pre-ox and giving a solid 5 min after you a sat of 99% can help wash out N2 + fill up your O2 resevoir -The larger the O2 reservoir, the longer your safe apneic time #emergencymedicine #emergencynurse #ems #resuscitation #criticalcare #prehospital #airway
won't improve your 1st pass success rate, rather provide safety buffer for when NOT successful. everything else on point tho

If you’re also not doing apneic oxygenation with a nasal cannula at 8lpm; you’re just wrong

I thought it was the dissolved nitrogen in the blood that we are trying to displace and the oxygen that takes its place is the actual reservoir for the hemoglobin to grab from.
