Brief Summary: Preoperative assessment of a patient and risk stratification is vital to reduce theperioperative surgical and anesthetic mortality and morbidity.There are many bedside tests to assess the functional capacity of a patient like 6 min walk test, breath holding test, spirometry, and matchstick blow test. These tests assess both the cardiopulmonary reserve and musculoskeletal system. Studies have shown that 6MWT has good predictive values for postoperative complications and is recommended test where CPET is unavailable.8These simple yet effective predictive tests are not commonly used in clinical practice. Bedside FC tests have been individually compared with various high endand gold standard test like CPET, NT pro-BNP, stress enzymes. To our literary knowledge, no studies have compared the correlation of preoperative bedside FC assessment with the commonly practice clinician judgment in obese patients.Hence, we aim to compare preoperative functional capacity assessment in obesepatients undergoing elective non cardiac surgery: Clinician Judgment and 6 Minute Walk Test.

Methodology.

Patient will undergo routine evaluation by the PAC consultant for fitness for anaesthesia. The functional capacity assessment of the recruited will be done by the concerned anesthesiologist in PAC based on various criteria- patient history, METs score, breath holding test. After the clinical examination by the PAC consultant, the METs score 10assigned by the PAC consultant will be documented and categorized into METs <4, 4-7, >7 indicating poor, normal and good functional capacity.

After the admission of the patient for the proposed elective surgery, the patient will be given a time slot and asked to report to department of anesthesiology preferably without heavy meals. The anesthesiologist blinded to the Functional capacity score assessed in PAC will conduct the 6 MWT. 6 MWT - a measured corridor course will used for walking with subjects instructed to walk from one end to other at their own pace attempting to cover as much distance as possible in the allotted 6 min. Location - a long, flat, straight, enclosed 30 m (100 feet) college corridor marked by cones will be used. The length of the corridor will be marked every 3 m by a color tape. The subject was rested for about 10 min in a chair, located near the starting position, before the test. During this time anthropometric parameters of the subject and the blood pressure were taken. An activity tracker with a pedometer app will be applied on the patientâ€™s wrist. As soon as the subject starts to walk, the timer will be set. Number of laps will be counted each time the subject returns to the starting point. Additional distance covered will also be recorded. The total distance walked, the post-test HR, BP, SPO2 and fatigue index by BORG scale will be recorded
