Conditions
Brief summary
Post-operative pulmonary complications (PPCs) have a major impact on patients and healthcare expenses. The goal of perioperative respiratory therapy is to improve airway clearance, increase lung volume, and mitigate atelectasis. Incentive spirometers (IS) are ubiquitously used to prevent atelectasis and PPCs-implementation of which requires substantial provider time and healthcare expenses. However, meta-analyses have demonstrated that the effectiveness of ISs is unclear due to poor patient compliance in past studies. The goal of this investigation is evaluate the effectiveness of IS on post-operative clinical outcomes. The aims of this investigation are to evaluate 1) if IS use compliance can be improved by adding a use-recording patient reminder alarm, and 2) the clinical outcomes of the more compliant IS users vs. the less-compliant IS users.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Compliance - Does the alarm improve IS use compliance? | up to 1 week postoperatively | The primary outcome will be to compare subjects' absolute IS usage count and hourly percent compliance in the Bell On arm vs the Bell Off arms. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Outcomes - Does IS use compliance improve clinical outcomes? | up to 1 week postoperatively | * Subjective American Thoracic Society's Dyspnea Index43 - administered daily in ICTU * ICTU Day 1: Baseline Dyspnea Index * ICTU Day 2 through discharge: Transition Dyspnea Index * Objective Trend during ICTU stay * Vital signs (T, HR, RR, BP) * O2 saturation * Oxygen requirements * CBC Bedside Pulmonary Function Tests (Micro 1, Carefusion) * Daily FEV1, FVC, FEV6, PEF, FEV1/FVC, FEV1/FEV6 and F25-75 ratios.
