Trial Title: Preoperative and Postoperative Incentive Spirometry in Patients Undergoing Major Abdominal Surgery

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: CROSSOVER
- Observational Model: None
- Primary Purpose: SUPPORTIVE_CARE
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 5.0

Eligibility Criteria:
Inclusion Criteria:~* Patients scheduled to undergo major abdominal surgery with expected postoperative length of stay of 48 hours or more.~* Access to a smartphone.~* At least 18 years of age.~* Ability to understand and willingness to sign an IRB approved written informed consent document.~Exclusion Criteria:~* Younger than 18 years of age~* No access to a smartphone

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Pre-Surgery: No Incentive Spirometry (IS) (Type: NO_INTERVENTION): -Will not receive a incentive spirometer prior to surgery
- Pre-Surgery: Standard Incentive Spirometry (IS) (Type: EXPERIMENTAL): * Will receive a conventional spirometer prior to surgery~* Will be asked to perform spirometry 30 times per day.
- Pre-Surgery: Digital Incentive Spirometry (IS) + Text Message (Type: EXPERIMENTAL): * Will receive the digital incentive spirometer (Spirobank G) that is compatible with health monitoring software developed by ZEPHYRx®. The digital spirometer couples with a HIPAA-compliant mobile application that calculates and stores pulmonary function test (PFT) results.~* Will be asked to perform spirometry 10 times per hour, every hour while awake, every day for at least 7 days prior to surgery. Absence of spirometry for 24 hours will trigger a text message reminder to encourage compliance with IS.
- Post-Surgery: Standard Incentive Spirometry (IS) (Type: ACTIVE_COMPARATOR): * After surgery, the participants will receive a conventional spirometer.~* Will be instructed to perform spirometry 10 times per hour, every hour while awake through postoperative Day 3~* The conventional spirometer will be equipped with an accelerometer that will allow the research team to determine whether the spirometer moves throughout the patients' postoperative stay (as a proxy for IS use)
- Post-Surgery: Digital Incentive Spirometry (IS) + Text Message (Type: EXPERIMENTAL): * After surgery, the participants will receive the digital incentive spirometer (Spirobank G) that is compatible with health monitoring software developed by ZEPHYRx®. The digital spirometer couples with a HIPAA-compliant mobile application that calculates and stores pulmonary function test (PFT) results.~* Will be instructed to perform spirometry 10 times per hour, every hour while awake through postoperative Day 3~* Will receive text reminders to perform spirometry if they do not perform spirometry in a 24-hour period.
