Clinical Trial Summary

To evaluate the feasibility of a fully randomized validation trial for the Oxalert EPO.


Description:

The investigators will evaluate the feasibility of a fully randomized validation trial for the Oxalert EPO. All patients will wear the Oxalert for 24 hours preoperatively in the monitoring only mode (no alerts), throughout hospitalization up to six days, and for 24 post-discharge hours. Randomization will be to Oxalert in monitor-only mode or to its normal mode which provides progressive audible and tactile alerts for hypoxemia.

Outcome

Type Measure Description Time frame Safety issue
Primary Time-weighted Average of SpO2 Below a Threshold of 90% Time-weighted average of SpO2 below a threshold of 90%. Oxygen Saturation measured between 0% - 100%. Oxygen Saturation <90% is considered abnormal. during hospitalization up to 6 days and post-discharge 24 hours
Primary Number of Participants With Desaturation Events (Saturation <90%) Lasting at Least 2 Min Number of Participants with Desaturation Events (Saturation <90%) Lasting at Least 2 Min. All the patients were included. during hospitalization up to 6 days and post-discharge 24 hours
Primary Duration of Desaturation Events (Saturation <90%) Lasting at Least 2 Min Duration of Desaturation Events (Saturation <90%) Lasting at Least 2 Mi. All desaturation events were included. during hospitalization up to 6 days and post-discharge 24 hours
Primary AUC of SpO2 Below a Threshold of 90% AUC of SpO2 Below a Threshold of 90%. SpO2 from 0% -100%. during hospitalization up to 6 days and post-discharge 24 hours
Primary Number of Desaturation Events (Saturation <90%) Lasting at Least 2 Min Number of desaturation events (Saturation <90%) Lasting at Least 2 Mi. All desaturation events were included. during hospitalization up to 6 days and post-discharge 24 hours
Secondary Patients' Attitude Toward the Device We used 0-to-10 (Better - Worst) numerical rating scale to measure the degree of disturbing: 0 = "Not disturbed" and 10 = "Severely disturbed"; others are measured with 5-point numerical rating scales:1="Strongly disagree", 5="Strongly agree" (1=Better - 5= Worst). No subscales combining to compute a total score. At the day of discharge and after 24 hours of discharge
Secondary Nurses' Attitude Toward the Device We used 0-to-10 (better- worst) numerical rating scale to measure the degree of disturbing: 0 = "Not disturbed" and 10 = "Severely disturbed"; others are measured with 5-point numerical rating scales:1="Strongly disagree", 5="Strongly agree" (1= better- 5=worst). Post-operative day 1 (POD 1)
