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

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.

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.

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).
