Harvard Study Conclusions

“Current technologies are ill-suited for measuring adequate ventilation in

the post-operative environment.” 


“The reason for Linshom’s accuracy and precision is based on its inherent

advantage of providing a continuous measurement of RR while using a

reduced time constant to detect breath changes more rapidly than


“Another advantage of the Linshom sensor was that it did not require

frequent calibration during the study.”   

“The Linshom technology may be a significant addition to monitoring vital

signs because it offers a minimally intrusive chance to detect respiratory

rate and apnea, without expensive or complex anesthetic equipment,

before the need for life-saving resuscitation arises. This can potentially avoid adverse events and enhance patient safety, thereby substantially reducing the need for costly interventions.”   

“This technology could also be employed in low resource settings such as natural disasters, humanitarian crises, or military conflicts where devices should preferably be portable, lightweight, durable, easy to use, readily

replaceable, and cost effective.”

Third Party Validation

Conducted in conjunction with:  


Harvard Brigham and Women's Hospital (Boston, MA) Department of

Anesthesiology, Dr. David Preiss

Cleveland Clinic (Cleveland, OH) Department of Gastroenterology and Hepatology, Digestive Disease Institute, Dr. John Vargo

Einstein Medical Center (Philadelphia, PA) Department of Emergency Medicine, Dr. Joseph Herres

-​ University of Mississippi Medical Center (Jackson MI) - Department of

Anesthesiology,  Dr. Madhankumar Sathyamoorthy   

The purpose of third-party validations for RR and Apnea was to compare

the performance of the Linshom technology of respiration detection—a technology that is based on exhaled temperature variations — with the

currently used technologies that are based on exhaled CO2.

Linshom relative tidal volume measurements were compared to those of a ventilator.
