In light of the blackouts in Cuba, US threats to stop power in Iran, Israeli strikes on Lebanon, and Russian strikes on Ukraine’s power grid, I will remind everyone that trying manually ventilate patients who can’t breathe for themselves is exhausting, technically challenging, and often fatally inadequate. It is very hard to sit there manually delivering 6 cc/kg of air with the right pressure, inspiratory time, and expiratory time, over and over again, for hours.
