Overall status: COMPLETED
Conditions: Postoperative Respiratory Complication
Respiratory Failure
Lead sponsor: Beth Israel Deaconess Medical Center

Accepts healthy volunteers: no
Observational model: COHORT
Time perspective: PROSPECTIVE
Sampling method: PROBABILITY_SAMPLE
Study population: We anticipate that our study population will reflect the normal distribution of race and gender of patients presenting for surgeries at BIDMC.

Brief summary: The aim of this study is to assess the capability of a modified under bed weighing scale (contact-free unconstrained respiratory monitor, BSS) to predict postoperative pulmonary complications in high-risk surgical patients.

The study is designed to test the hypothesis that abnormal breathing measured by a modified under bed weighing scale predicts postoperative pulmonary complications within 7 days after surgery.


Eligibility criteria: Inclusion Criteria:

1. Age 18 years or older
2. Undergoing non-cardiac surgery under general anesthesia.
3. Score ≥ 25 in the risk prediction score (Table1)

Exclusion Criteria:

1. Ambulatory (outpatient) surgery
2. Transfer directly to the ICU
3. Remain intubated/ planned to remain intubated after surgery
4. Pregnant patients: as detected by patient self-reporting of diagnosed by preoperative pregnancy testing according to institutional policies at BIDMC.
5. Patients enrolled in other interventional studies which could confound the primary endpoint.
