NCT05356754
The primary endpoints for this study are mean and standard deviation error measurements for the VLDBPM versus manual auscultation.
NCT05139693
The aim of this project is to test the accuracy of pulse oximeters during mild, moderate and severe hypoxia. This is done by comparing the reading of the pulse oximeter during brief, steady state hypoxia with a gold-standard measurement of blood oxyhemoglobin saturation (arterial blood sample processed in a laboratory hemoximeter). The data obtained is submitted by pulse oximeter manufacturers to the FDA for device approval.
NCT00346164
This phase III trial is studying observation to see how well a risk based treatment strategy works in patients with soft tissue sarcoma. In the study, patients are assigned to receive surgery +/- radiotherapy +/- chemotherapy depending on their risk of recurrence. Sometimes, after surgery, the tumor may not need additional treatment until it progresses. In this case, observation may be sufficient. Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as ifosfamide and doxorubicin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving chemotherapy and radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving these treatments after surgery may kill any tumor cells that remain after surgery.
