hey Alessia
yes i think first we should practice on each other rather than applying directly on the patient. practice makes the man perfect my boss used to do it very well but being a man he was able to lift and position the patient far better than me !!
and thrust in my personal view should be avoided because even if our positioning is fine the patient may get paniced and move or tilt head....that can cause serious issue.
grade 4 is good so its better to give under than over does
