Eligibility

Inclusion criteria

Inclusion criteria: All patients above 18 years of age undergoing BOT and admitted to the hospital.

Exclusion criteria

Exclusion criteria: 1.Patients who refuse to consent for the procedure 2.Technical difficulty in obtaining baseline values of rSO2 or BIS 3.Contraindications to BOT 4.Any patient requiring sedation or general anaesthesia.

Design outcomes

Primary

MeasureTime frame
1.To study the changes in bilateral rSO2 and BIS in patients who fail the BOT as compared to patients who pass the BOT clinically. 2.To evaluate the association between â??rSO2 (Baseline rSO2- rSO2 post balloon occlusion) with venous phase delay of patients who fail the BOT as compared to patients who pass the BOT clinically.Timepoint: Bilateral rSO2 and BIS values will be recorded at â?¢Baseline â?¢Before balloon occlusion and every 5 minutes thereafter â?¢Immediately before deflation â?¢Post balloon deflation. If hypotensive challenge is administered, additional values will be obtained â?¢Before hypotension â?¢Every five minutes thereafter â?¢Immediately pre and post balloon deflation
