While reusable sensors are effective, disposable SpO2 sensors address key challenges in modern healthcare. They remove the burden and inconsistency of sterilization protocols, which are critical in busy clinical environments. By ensuring every patient receives a brand-new, hygienic sensor, facilities significantly reduce the risk of hospital-acquired infections (HAIs). Furthermore, they provide long-term cost-effectiveness by reducing potential costs associated with cross-infection complications and by streamlining clinical workflows.
