5. what is weaning?: the process of gradually reducing ventilator support
and allowing the client to assume greater responsibility for breathing
spontaneously
6. what types of weaning are there?: spontaneous awakening trial
spontaneous breathing trial

a stable respiratory drive and adequate O2 saturation
8. during a weaning trial, what assessment finding would indicate a need to
end the trial?: tachypnea dyspnea tachycardia dysrhythmias

failure?: high CO2
(>45)
