Final answer:
Pressure-supported ventilation (PSV) has primary uses in recruiting collapsed alveoli, improving oxygenation and augmenting patient's spontaneous VT.
Step-by-step explanation:
Pressure-supported ventilation (PSV) has several primary uses:
- Recruiting collapsed alveoli and improving oxygenation: PSV can help open airways and increase the volume of the alveoli, allowing for better gas exchange and improved oxygenation.
- Augmenting patient's spontaneous VT: PSV helps support the patient's breathing efforts and can assist in maintaining adequate tidal volume.
- Overcoming the imposed work of breathing: PSV reduces the work required by the patient to breathe by providing additional pressure support.
Therefore, the correct answer is: A) I and II
