Focusing your topic

For this assignment help we are using the topic: Alveoli and gas exchange

Focusing your topic is key, for example looking at only the respiratory system would be too broad.

Plan before you search

Planning your search will give you the best chance of finding relevant results.

Take some time to either brainstorm, map out (mindmap) or table possible search concepts.

Mind mapping
Mind maps can help you visual information and relationships between them. Use them to brainstorm and organise your ideas.

You may find it easier to start a table for each concept and add other possible synonyms or alternative concepts as you discover them.

Example topic: alveoli and gas exchange


Key concept Synonyms and alternative concepts



Capillary, Capillaries


TIP: You may have to search more broadly on the lungs to find information on the alveoli.

Gas exchange

Gaseous exchange

Exchange of gases

Alveolar air


We recommend you watch the following video:

Example topic: aveoli and gas exchange

Use the following steps to plan your search:

  1. Define and terms you are unsure of. Use Anatomy TV to find overviews.
  2. Identify the main concepts you will search on. This will form the foundation of your search.
    • Concept 1: Alveoli
    • Concept 2: Gas exchange
  3. Identify any synonyms or related concepts keywords for each main concept.
    • Concept 1: Alveoli, alveolus, capillaries, lungs
    • Concept 2: Gas exchange, gaseous exchange, exchange of gases

Consider any:

  • word plurals - alveoli or alveolus
  • different word forms - (obese or obesity / diabetic or diabetes)
  • different word spellings - homeostasis or homoeostatis / celiac or coeliac),
  • common acronyms (BMI or Body Mass Index / CVA or cardiovascular disease)

Finding peer reviewed articles

In PubMed we recommend you use the Advanced Search option so you can do a guided search.

Start  by putting each different concept on a new line. Notice your different concepts are connected with AND.

Search for phrases using double quotes "..."

Try broadening your search by adding some synonyms or alternative concepts to each line. Connect these with OR.

If you are looking for recent articles limit your search by publication date on the left hand menu.

In Emcare you will need to search each different concept one at a time.

Important: Untick Map term to Subject Heading as we just want to do a keyword search.

Start by typing your first concept in the search box and select search.


Now enter your second concept into the search box. Use OR to search for any synonyms or alternative concepts. Select search.


Once you have searched for all your different concepts, select each concept by ticking the box next to it and then connect them using AND.

You can find recent results by limiting your search by publication date.

Google scholar can be a good starting point for finding peer reviewed articles.

Remember, always access Google scholar from the library homepage to see full text content.

Start by typing your key concepts into the search box:

You can use the connector OR to add any synonyms or alternative concepts:

Changing your search will find different results. For example you could try:

Use the Library Catalogue to find books, book chapters, reports and articles.

Start with a basic keyword search:

Further search strategies

If you are having trouble finding relevant results try these strategies:


  1. Substitute one search concept for another. Remember authors refer to concepts in different ways.
  2. Try a different search tool. Different ones will return different results.
  3. All you need is one relevant article. If you find one:
    • read the abstract to see if there are any other concepts you could use to broaden your search
    • look at the reference list. Could some of resource be useful?
