In most weaning protocols, what minimum blood gas parameters are needed to start the process? A) PaO₂ greater than 70 mm Hg and PaCO₂ less than 50 mm Hg on FiO₂ less than 0.6 and PEEP less than 5 cm H₂O B) PaO₂greater than 70 mm Hg and PaCO₂ less than 50 mm Hg on FiO₂ less than 0.4 and PEEP 5 cm H₂O or greater C) PaO₂ greater than 50 mm Hg and PaCO₂ less than 50 mm Hg on FiO₂ less than 0.6 and PEEP less than 10 cm H₂O D) PaO₂greater than 70 mm Hg and PaCO₂ less than 70 mm Hg on FiO₂ less than 0.6 and PEEP 5 cm H₂O or greater

The weaning protocol typically requires a minimum PaO2 of 70 mm Hg and a maximum PaCO2 of 50 mm Hg on an FiO2 of less than 0.4 and a PEEP of 5 cm H2O or greater to start the process. Option A is incorrect because it requires a PEEP of less than 5 cm H2O, which is insufficient for adequate oxygenation. Option C is incorrect because it allows for a PaO2 of less than 70 mm Hg. Option D is incorrect because it allows for a PaCO2 of greater than 50 mm Hg.
