Sustainability interventions in nursing wards

Monitoring parameters

Reusable pulse oximeters

Measuring a patient’s oxygen saturation is an essential part of patient care. Due to their high consumption in hospitals, disposable pulse oximeters have a considerable environmental impact.

Intervention

Replace disposable saturation sensors with reusable saturation sensors. Exclusion: the neonatology department because of the different sizes of saturation sensors in neonates.

Exclusion: pediatric departments because of the different sizes of saturation sensors used in infants and neonates.

Implementation approach

Look at the approach for implementing a (reusable) product and consult the step-by-step guide for more information on setting goals, implementation, and evaluation.

Environmental impact

Measured in CO2 -emissions by reducing the number of disposable saturation sensors and reusing saturation sensors. Want to know more about the environmental impact? See the bottom of this page for more information.

Current situation

Measure saturation once with a disposable saturation sensor (adhesive sensor) = 0.19 kg CO2-eq

New situation

Measure saturation once with a reusable saturation sensor (clip) and clean = 0.02 kg CO2-eq

-90% CO2

The environmental impact of the disposable saturation sensor is approximately 10 times higher than that of the reusable sensor.

Measuring three times a day for a year with a reusable sensor instead of disposable measurements saves

186

kg CO2-eq

and is equivalent to driving 955 km

When is it implemented?

This intervention was implemented when nursing wards in the hospital switched to reusable pulse oximeters and the difference in kg of CO2 equivalent has been calculated.

How is this measured?

The environmental impact of this intervention can be determined using the purchase data for the number of disposable pulse oximeters, see method of measuring intervention with purchasing data.
