Effect of Pursed-lips Breathing Combined With Aerobic Walking Exercise on Oxygenation and Activity Endurance in Lung Cancer Patients After Lobectomy

Effect on Postoperative Oxygenation in Lung Cancer Patients

Measurements were taken on the 1st day after surgery, prior to the intervention. The pulse oximeter was placed on the patient's fingertip, and after a 5-second wait, the SpO2 value appeared on the monitor interface, which was then recorded on the data sheet.

Time frame: pretests(before the start of the three interventions on the post-op day 1)

Effect on Postoperative Oxygenation in Lung Cancer Patients

Measurements were taken on the 5th day after surgery, after three activities. The pulse oximeter was placed on the patient's fingertip, and after a 5-second wait, the SpO2 value appeared on the monitor interface, which was then recorded on the data sheet.

Time frame: posttests(after the completion of the three interventions on the post-op day 5)

Dyspnea Visual Analogue Scale (DVAS):Draw a vertical 10 cm line on an A4 white paper. Label the top end of the line as "Not Breathless" and the bottom end as "Very Breathless." The longer the distance marked on the line, the more severe the breathlessness. Measurement Method: Measurements were taken on the 1st day after surgery, prior to the intervention. After the patient completes a six-minute walk test, they mark their level of breathlessness on the vertical line to assess the degree of breathlessness.

Effect on Postoperative activity endurance in Lung Cancer Patients

Six-minute walking test (6MWT) : A long, flat, unobstructed hospital corridor is selected as the testing location. The floor is marked every 1 meter, covering a total distance of 30 meters. Patients are instructed to walk back and forth within the marked distance. Before the test, patients are informed to walk at the fastest pace they can tolerate and that they can slow down or pause if they experience any physical discomfort during the test. The test lasts for six minutes, and when the time is up, patients stop walking. The location where patients stop is recorded, corresponding to a marked point on the floor. The distances covered are summed up to determine the test result.

Effect on Postoperative activity endurance in Lung Cancer Patients

Rating scale of perceived exertion (RPE / Borg 6-20):This scale ranges from 6 points (indicating no perceived exertion) to 20 points (indicating maximal exertion). Higher scores indicate a higher level of perceived exertion.Measurements were taken on the 1st day after surgery before the intervention. After the six-minute walking test, patients were asked to circle the score on the scale that corresponds to their perceived level of exertion to assess the level of exertion felt by patients after activity.

Rating scale of perceived exertion (RPE / Borg 6-20):This scale ranges from 6 points (indicating no perceived exertion) to 20 points (indicating maximal exertion). Higher scores indicate a higher level of perceived exertion.Measurements were taken on the 5th day after surgery after three separate activities. Following the six-minute walking test, patients were asked to circle the score on the scale that corresponds to their perceived level of exertion to assess the level of exertion felt by patients after activity.
