Hypoxia takes hold when the oxygen level in a person's arterial blood-flow to the brain is too low. Without enough 02, pilots can experience tingling in their extremities, tunnel vision and an ever-worsening ability to safely control the airplane. Oxygen deprivation is difficult to self-diagnose because symptoms, masked by a sense of euphoria, appear gradually. Masimo Personal Health thinks its hospital-quality MightySat pulse oximeter may help prevent hypoxia, and it's certainly better than climbing up high in an unpressurized airplane and hoping for the best.
