November 9, 2023 this special day, the University of California (formerly Nellcor) Professor Bickler and Mr. Mike came to China to guide the General Hospital of Shenzhen University for "hypoxia laboratory" on-site training, including the purpose of the experiment, experimental steps, safety matters, the new ISO standards, etc., and on the Shenzhen Vitreous Leaf Medical Electronics Co., Ltd. the new development of multi-parameter The oxygen measurement performance of the monitor (G3) for pre-experimental verification, according to the pre-experimental program to arrange five people (one of them is black skin) for non-invasive comparison, each person to carry out two rounds of controlled hypoxia experiments, each step of the comparison of the data recorded by the preliminary statistical analysis, to achieve the desired design goals, but also to the relevant products for pre-experimental comparison, to provide support for the subsequent formal experiments!

The following are some of the experimental photos, a true record of the experimental process, intuitive process makes the data more reliable, Witleaf's products have accurate measurements, backed by a strong team, released every product, have undergone clinical trials, and the formation of clinical reports.
