About

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.

Enrollment: 16 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
