Final answer:
A Spontaneous Breathing Trial (SBT) is also known as a weaning trial and is used to test a patient's ability to maintain pulmonary ventilation after being mechanically ventilated. Various parameters, including MVV and SVC, are monitored during the trial.
Step-by-step explanation:
A Spontaneous Breathing Trial (SBT) is a method of assessing the ability of a patient who has been on mechanical ventilation to breathe on their own.
The correct term that SBT can also be known as is a weaning trial. This trial is crucial in the process of weaning patients from mechanical ventilation and involves monitoring their ability to maintain effective pulmonary ventilation without support. Key respiratory parameters assessed during a weaning trial include Maximum Voluntary Ventilation (MVV), Slow Vital Capacity (SVC), Total Lung Capacity (TLC), Functional Residual Capacity (FRC), and Residual Volume (RV).
