Now you might notice, due to turning down the level of sedation, the patient may start to take a few more spontaneous breaths on their own. This is where Pressure Support Ventilation (PSV), another type of mode, comes into it. In today's episode, I detail the setting of Pressure Support; and mention at what stage we may switch the patient from a 'Rate' (ie SIMV) to PSV; and highlight a few key things for nurses to keep an eye on when doing so.
