circuits and airways management

Description of the gas flow in a Bain circuit is:

• Fresh gas – reservoir bag – outer tube – animal – inner tube - Scavenge

• Fresh gas – animal – open ended bag – scavenge

• Fresh gas – animal – Waters canister – rebreathing bag – Waters canister – animal/scavenge

• Fresh gas – inner tube – animal – outer tube – reservoir bag - Scavenge

In correctly intubated animals, an advantage of endotracheal tubes is:

• Increase in saliva production

• Increase in traumatic laryngitis

• Reduction in anatomical dead space

• Increase in waste-gas pollution levels

Ischaemic tracheitis may be caused by:

• The over-inflation of endotracheal tube cuffs

• Failure to rinse cleaning chemical from endotracheal tubes

• The use of over long endotracheal tubes

• Pharyngeal irritation by the endotracheal tube

The inner tube of a coaxial Bain circuit pictured contains:

• A mixture of fresh and expired gas

• Water vapour

• Expired gas

• Fresh gas

Poly vinyl chloride endotracheal tubes are known for:

• Being constructed of red rubber

• Being the least irritating to the tracheal mucosa

• All incorporating cuffs

• Their poor resistance to kinking

The anaesthetic period is said to have ended when:

• The animal has swallowed

• The animal has opened its eyes

• The endotracheal tube is removed

• The animal has regained consciousness

Which is the correct order of oxygen flow from a cylinder to a patient in the anaesthetic machine?

• Cylinder, reducing valve, vaporiser, rotameter, endotracheal tube

• Cylinder, reducing valve, rotameter, vaporiser, endotracheal tube

• Cylinder, vaporiser, rotameter, reducing valve, endotracheal tube

• Cylinder, rotameter, reducing valve, vaporiser, endotracheal tube

What type of circuit is most suited for anaesthesia in a Great Dane?

• Circle

• Coaxial bain

• Modified lack

• Waters to and fro

Laryngospasm is most likely to occur in:

• Dogs

• Cats

• Rabbits

• Birds

‘I.P.P.V’ is an abbreviation for:

• Interval positive pressure ventilation

• Intermittent positive pressure ventilation

• Intermittent performed personal ventilation

• Interval person performed ventilation
