14. 1)Take measurements:
- temple to temple
-head circumference
- forehead/brow to sternal region
2) Cut transparent material using
measurements above. It should cover Rt to Lt
temple (width) and forehead to chest (length)
3) Cut the belt (length is 15cm+head
circumference), then into two equal halves.
4) Place material on a flat clean surface
5) Staple/stitch belts to both upper ends of the
material
6) Cut soft foam/fibre (about 4cm wide and
long enough to cover forehead) - this is for
comfort on the forehead skin

15. • Don’t shake hands/hug
• Look through notes/find out history before patient comes into room
• Remain 2m away from patient when possible
• Only do pertinent parts of examination, and when close to patient for
examination, ask them not to speak unless necessary, and to touch the
examination equipment as little as possible
• Use single-dose eye drops
• AVOID:
• Air puff tonometry – only do tonometry if needed, and ideally
use e.g.Tonopen/i-Care/Goldmann with disposable tip
• Direct ophthalmoscopy – use indirect
• Close examination for longer than necessary, inc. investigations
• General anaesthetic (= aerosol-generating procedure), unless
essential
• Nasal endoscopy
Examining the Patient
16. • Wear disposable gloves to clean
• Recommended disinfectants include:
• Diluted household bleach (5tbsp per
gallon of water)
• OR at least 70% alcohol
• OR various household cleaning
products, verified to kill viruses
• Clean:
• Surfaces in the room, inc. door handles,
panels, phones
• Examination equipment, inc. the slit
lamp, breath shield, controls, handles
and chin/forehead rest
• Tonometer tip (while 70% alcohol will
not sterilize against adenovirus, it will
against SARS-CoV-2)
After each interaction – Cleaning Surfaces
