4 Clinical Trials for Various Conditions
The goal of this study is to compare the time required for accurate heart rate measurement of the preterm newborn when using pulse oximetry versus electrocardiography leads.
Monitoring heart rate during exercise can provide feedback to the patient and provider that the patient is exercising in the appropriate, individualized and safe range for them. This is particularly important in a group setting when multiple individuals are supervised by one provider. This study is interested in assessing the difference in intensity of care delivered when visual feedback of heart rate is provided compared to no visual feedback of heart rate in rehabilitation. Visual feedback of heart rate will be provided through Heart Zones, a platform which synthesizes multiple signals from externally worn heart rate monitors. This study is interested in better understanding the acceptability, feasibility and appropriateness of this technology when used in rehabilitation.
This protocol will test a new non-invasive device, the T-line, in continuously determining heart rate and blood pressure in operative and critically ill patients. The accuracy of the device will be compared to the standard radial artery catheter, as well as to the non-invasive blood pressure cuff. The T-line will also be compared to the right heart catheter determining cardiac output in at least 20 patients. Hypothesis: the T-line device will determine blood pressure and heart rate as accurately as a standard radial arterial catheter and a blood pressure cuff in perioperative patients.
The purpose of this study is determine the diagnostic performance of dual energy computed tomography perfusion for non-invasive assessment of the hemodynamic significance of coronary stenosis, as compared to a direct measurement of fraction flow reserve during cardiac catheterization as a reference standard. The overall objective of the present study is to determine the diagnostic performance of dual energy computed tomography perfusion for non-invasive assessment of the hemodynamic significance of coronary stenosis, as compared to direct measurement of fraction flow reserve during cardiac catheterization as a reference standard.
