A STATE-OF-THE-ART intensive care unit in a Barcelona hospital features lighting whose spectral output can be tuned to exactly match natural daylight.
The facility at Barcelona’s Vall d’Hebron hospital use of seven LED engines that span the visible range without any gaps in the spectral power distribution.
This flat profile is achieved thanks to a careful combination of single-peak LEDs and phosphor-converted LEDs. Wavelength shifts are compensated for via feedback from an onboard spectroradiometer.
The human-centric lights – developed by scientist Meritxell Carreras, CEO of Barcelona-based company Ledmotive – are designed to mimic sunlight dynamically but in theory could be individually tuned to match any spectral signature.
‘When there’s a serious problem, like a cardiac arrest, the very same building is capable of providing the conditions for professionals to attend to the patient correctly,’ explained Doctor Ricard Ferrer, head of intensive care at the hospital.
All patient info is linked to a smart screen where hospital staff can monitor their progress. A blue light before the patient’s room warns if they are about to enter a critical situation, and the doors open automatically allowing easier access.
Substituting the previous unit, this ICU comes with an extension of 3,500 square metres and 56 individual spaces for patients, making the biggest in Spain as a whole. Its budget was 20 million euros.
‘This smart ICU incorporates the very latest technology for giving the best care for patients in a critical condition,’ said health minister Alba Vergés.
There are even ‘smart beds’ that are connected to the Smart Display, relaying information such as the patient’s weight, movements, position so they do not spend too much time immobile, and warnings of falls.
The unit expects to attend to around 2,200 patients each year.
