What can I do to get the best out of this Unit?


If you’re really serious about getting the best out this unit and are prepared to put some extra time in on your own, it would be great if you could do some of the following:

 

Get together and organise a visit to a local health centre for a demonstration of the technical equipment used to monitor the health of patients.

 

Organising a visit to a local hospital to observe the use of equipment such as ultrasound monitoring can really help too as you’ll get to see it first hand, in practice rather than in theory
