Feasibility of Measuring Volume of Inspiration Via Noninvasive Motion Sensors
Completed · Not applicable
Conditions studied: Postoperative Pulmonary Complications (PPCs)
In brief
Background: Lung problems develop in up to 20% of people after they have surgery. While under general anesthesia, people breathe slower and draw in less air. They may have difficulty returning to normal deep breathing as they recover. Some may develop life-threatening complications. An approved device called an incentive spirometer is used to help measure and improve a person's breathing after surgery. Researchers want to find out if a motion sensor placed on the chest can also measure the volume of air a person inhales as they breathe. Objective: To determine if a motion sensor on the chest can measure the volume of air a person breathes. Eligibility: Healthy adults aged 18 years and older. Design: * Participants will have one clinic visit. The visit will last 10 to 30 minutes. * They will fill out a form with their age, sex, height, and weight. * A small, plastic motion sensor will be taped to their chest on one or both sides. * Participants will breathe through a tube attached to an incentive spirometer. They will take 18 breaths of different volumes, both deep and shallow. * Researchers will use the data collected from the motion sensors to measure how the chest moves at different levels of breathing. The motion sensor data will be used to create a software program that converts chest wall motion to the volume of air inhaled for a given breath in real time.
