Acerca de la investigación
This randomized controlled pilot study will compare intermittent positive pressure breathing (IPPB) with incentive spirometry (IS) in adult patients undergoing thoracic surgery. The study aims to evaluate the effects of these two postoperative pulmonary rehabilitation interventions on lung volume recovery, respiratory muscle strength, oxygenation, pulmonary complications, and overall postoperative recovery. Participants will be randomly assigned to either the IPPB group or the IS group. Assessments will be performed before surgery and after the intervention period.

This is a single-center, randomized controlled pilot study conducted at Fu Jen Catholic University Hospital. A total of 30 adult patients undergoing thoracic surgery will be enrolled and randomly assigned to one of two intervention groups: intermittent positive pressure breathing (IPPB) or incentive spirometry (IS).
Before surgery, participants will undergo baseline assessments including blood sampling, lung volume measurement, chest X-ray, respiratory muscle strength assessment, and pulmonary function evaluation. After surgery, participants will receive the assigned pulmonary rehabilitation intervention from postoperative day 0 through postoperative day 3.
Participants assigned to the IS group will perform supervised slow and deep inspirations using an incentive spirometer 3 to 4 times per day, with three sets of 10 breaths per session. Participants will also be encouraged to practice independently while awake. Participants assigned to the IPPB group will receive intermittent positive pressure breathing as the postoperative lung expansion intervention according to the study protocol.
Follow-up assessments will be performed after the intervention period. Outcomes will include changes in lung volume; maximal inspiratory and expiratory pressures; physiologic parameters including heart rate, respiratory rate, and blood pressure; chest X-ray findings; pulmonary function; arterial blood gas measurements; peripheral oxygen saturation; dyspnea; pain; and postoperative pulmonary complications. Blood samples will also be collected to evaluate C-reactive protein as an indicator of postoperative inflammatory response.
The study is designed to evaluate the feasibility of the study procedures and to obtain preliminary estimates of treatment effects that may be used to inform the sample size and design of a future definitive randomized controlled trial.

Intermittent Positive Pressure Breathing Group
Participants assigned to this group will receive intermittent positive pressure breathing (IPPB) as the postoperative lung expansion intervention from postoperative day 0 through postoperative day 3.
Other: Intermittent Positive Pressure Breathing
Incentive Spirometry Group
Participants assigned to this group will perform postoperative lung expansion training using incentive spirometry from postoperative day 0 through postoperative day 3.
Other: Incentive Spirometry
Intermittent Positive Pressure Breathing OTHER
Intermittent positive pressure breathing will be provided as a postoperative lung expansion intervention from postoperative day 0 through postoperative day 3.
Incentive Spirometry OTHER
Participants will perform incentive spirometry from postoperative day 0 through postoperative day 3 under therapist supervision 3 to 4 times per day. Each supervised session will consist of 3 sets of 10 slow, deep inspirations, with a 2- to 3-second inspiratory hold. Participants will also be encouraged to practice independently while awake.

Medidas principales
Change in Lung Volume
Plazo: Baseline (preoperative) and postoperative day 3
Change in lung volume, including tidal volume and minute ventilation, measured using a respiratory volume measurement device.
Change in Maximal Inspiratory Pressure
Plazo: Baseline (preoperative) and postoperative day 3
Change in maximal inspiratory pressure (MIP) measured using a respiratory pressure measurement device to assess inspiratory muscle strength.
Change in Maximal Expiratory Pressure
Plazo: Baseline (preoperative) and postoperative day 3
Change in maximal expiratory pressure (MEP) measured using a respiratory pressure measurement device to assess expiratory muscle strength.
Medidas secundarias
Change in C-Reactive Protein
Plazo: Baseline (preoperative) and postoperative day 3
Change in serum C-reactive protein (CRP) concentration as an indicator of postoperative inflammatory response.
