“The Makani Science breathing sensor offers the promise to continuously monitor a patient’s pulmonary function – respiratory rate, tidal volume and minute ventilation – wirelessly and noninvasively.

"It is a simple, direct and intuitive way to know how the patient is breathing.”

Dr. Steve Yun,

Western University of Health Sciences, American Association for the Accreditation of Ambulatory Surgical Facilities

The Clinical Need

Market Opportunity

Global market for respiratory
monitoring devices

(pulse oximetry, capnography, spirometry, peak flow meters)
  • Exponential growth of outpatient medical and dental procedures using mild or moderate sedation

  • Frequent use of powerful opioids for post-operative pain management

  • Aging population afflicted by chronic conditions, such as obesity and cardiovascular disease, that is at higher risk for sedation-related respiratory failure

Our Solution

  • It is a wearable patch sensor that continuously monitors breathing – respiratory rate, relative tidal volume and minute ventilation.

  • The patient’s respiratory waveforms are monitored in real-time on a mobile platform, such as smart phones, tablet computers, or other portable computers.

  • It enables healthcare professionals to immediately detect and manage respiratory events with no lag time
