SleepImage has the only FDA-cleared measure of Sleep Quality.
The Sleep Quality Index (SQI) has been associated with health outcomes, particularly cardiovascular and cardiometabolic health in both children and adults.
The SQI is not a marketing slogan, it is a clinical management tool, reflecting parasympathetic activation during sleep.
Measuring sleep quality is important for good patient care, and limiting a sleep test to respiration can lead to suboptimal or even incorrect clinical diagnosis and therapy.
