The relationship between ventilation and oxygen uptake becomes non-linear above the anaerobic threshold. This threshold can be determined by establishing a ratio of inspired volume and VO2 consumption. Anaerobic threshold also known as lactate threshold (LT) or lactate inflection point (LIP) is the point when lactic acid starts to amass in the blood stream.
Use AcqKnowledge® to establish a ratio of inspired volume and VO2 consumption and to integrate the air flow signal to obtain total inspired volume in real time.
Divide the identically integrated O2 consumption flow signal by the inspired volume; the resultant value will be constant to the point of anaerobic threshold. After the threshold is reached, this value starts to drop.

The ETVision (ETV) wearable unit resembles an eyeglasses frame that can be worn by itself or over the participant’s prescription eyeglasses. It contains miniature “eye cameras” that view each eye and a “scene camera” that views the scene in front of the participant, and a microphone. An optional visor can be mounted to the front […]
View AllSolving Physical Stress Issues for Surgeons Physical stress in the operating room is common for surgeons, considering how much time they spend in an upright standing position during surgical procedures. With procedures that require standing for several hours and average reported working times of 60-80 hours a week, surgeons seem to be at risk for musculoskeletal […]
