About
This is the second part of a research study in order to determine if using a specialized pulse oximetry probe with external heat pack will help obtain oxygen saturation (SaO2) and heart rate (HR) during monitoring for patients with peripheral vascular disease (PVD), vasoconstriction, and hypothermic extremities. The inability to obtain accurate SaO2 and pulse readings can lead to misdiagnosis, incorrect treatment, or procedures to be canceled. SaO2 and pulse readings are important to maintain patient stability during diagnostic testing, surgical procedures and monitoring while in critical care areas. Changes in SaO2 and pulse are important to monitor in order to be able to compensate for any decrease in patient oxygen saturations during hemodynamic monitoring.
The primary aim of this study is to determine if using a specialized pulse oximetry probe with external heat pack will improve oxygenation readings in order to obtain SaO2 and pulse readings in patients with PVD, vasoconstriction, and hypothermic extremities as compared to readings obtained from an arterial blood gas.
The hypothesis is using a specialized pulse oximetry probe with external heat pack will help obtain more accurate pulse oximetry readings consistent with values obtained with an arterial blood gas.
Full description
150 patients will be approached in order to ensure 110 patients will be enrolled in this study total. 30 patients will have peripheral vascular disease (PVD), vasoconstriction, or hypothermic extremities and 80 patients with no blood flow issues will be enrolled. The patients will serve as their own controls. Each patient will have a specialized pulse oximetry probe with external heat pack added to their extremity while measuring pulse oximetry. These SaO2 readings will be compared to SaO2 readings obtained from an arterial blood gas obtained during the course of the study.
