Lifebox has prioritized identifying and assuring an accurate pulse oximeter for patient use.
The effect of skin pigmentation on pulse oximeter measurement accuracy has been previously documented (Bickler et al. 2005). Lifebox has prioritized identifying and assuring an accurate pulse oximeter for patient use.
The Lifebox pulse oximeter, manufactured by Acare Technology Co., Ltd. in Taiwan, has been assessed for functionality in the field and accuracy on a range of different skin tones confirmed in standard and controlled laboratory assessments, including breathe down testing. The Lifebox pulse oximeter by Acare has also been included in the Newborn Essential Solutions and Technologies (NEST360°) Qualified Technologies for Newborn Care in Low-Resource Settings list (June 2020).
Lifebox is in the process of procuring its next generation pulse oximeter. Assuring accuracy across a range of skin tones is a core component of our target product specifications. The shortlisted devices are currently in the process of being tested for accuracy by the University of California San Francisco Hypoxia Laboratory. Variations in skin pigmentation and resultant oximetry readings will be a critical component of this testing.
