Study Overview
Brief Summary
For patients undergoing colorectal surgery, post-operative pulmonary complications (PPCs) are common. PPCs are associated with increased morbidity and mortality, as well as prolonged hospital stays and healthcare costs. Pulmonary exercise in the pre-operative setting is thought to improve pulmonary fitness and decrease incidence of PPCs. Use of an oscillating positive expiratory pressure (OPEP) device sees patients improve their respiratory fitness through prescribed usage of a handheld instrument that exercises pulmonary muscles while breathing. Here, the investigators propose a pilot randomized-controlled trial (RCT) to evaluate the feasibility of a large scale study that would examine the effect of preoperative OPEP device exercises in preventing PPCs for patients undergoing elective colorectal surgery.

Outcomes
Primary Outcomes
Trial feasibility: limited efficacy of the OPEP device
Time Frame: 18 months
Limited efficacy of the OPEP device to decrease post-operative pulmonary complications (PPCs). PPCs represents a composite outcome including atelectasis, pneumonia, prolonged requirement for supplemental oxygen, and respiratory failure.
Trial feasibility: capacity for recruitment
Time Frame: 18 months
Ability of clinics to recruit patients in a timely manner. To be reported as a percent of the desired number of patients recruited over an 18 month period.
Trial feasibility: device adherence
Time Frame: 18 months
Adherence of enrolled patients to usage of the OPEP device. To be reported as percent of patients returning a complete logbook detailing their consistent use of the OPEP device pre-op and post-op.
Trial feasibility: data collection
Time Frame: 18 months
3\) Completeness of data collected from enrolled patients medical record. To be reported as a percent of recruited patients with complete datasets following the trials completion. Used to identify gaps in data for a future fully powered trial.
Secondary Outcomes
