Healthcare Lighting Q&A
What is COI?
COI Stands for Cyanosis Observation Index. It is a unit of measure that has been used in Australia and New Zealand since 1997 (with the most current of the lighting standard AS/NZS 1680.2.5:2018). In particular, the index value describes a light source’s suitability for visual detection of cyanosis in a patient. The lower the value of the index, the better the light source is deemed to be for that purpose.
Which New Zealand standard covers Cyanosis Observation lighting for healthcare?
The following standard covers in detail the Cyanosis requirements for lighting: AS/NZS 1680.2.5:2018
What considerations should I make when designing lighting for hospital and medical applications?
When lighting patient rooms it is important to consider:
• The comfort and wellbeing of patients
• The needs of the medical staff for examination, treatment and observation of patients.
• The lighting needs of the staff involved with cleaning these areas.
How do I meet standards for lighting patient rooms?
Patient rooms and similar areas should consider the physiological and psychological wellbeing of the patient. Uniformity recommendations in Section 3 of AS/NZS 1680.1:2006 need not be applied in these areas. The patient room is not viewed from a normal perspective, sitting or standing. It is therefore important that where these conditions can be predicted that the lighting is directed or controlled to avoid discomfort to the patient.
Where can I find the standards and lighting recommendations for hospitals and medical premises?
In both New Zealand and Australia lighting is required to meet the following healthcare specific standard:
AS\NZS 1680.2.5:1997 – Interior Lighting Hospital & Medical Tasks (Table F1)
