This is an observational, proof-of-concept, feasibility study where 50 preterm infants with gestational age < 32+0 weeks will be recruited from the neonatal intensive care unit (NICU) at the Montreal Children's Hospital. The study's primary objective is to describe the relationship between respiratory acoustics and airflow and determine the reliability of a novel respiratory acoustic sensor at detecting breathing sounds in preterm infants. The study's secondary objectives are: 1. To compare transthoracic impedance, respiratory inductive plethysmography and an inertial measurement unit for the detection of respiratory efforts in preterm infants. 2. To evaluate the feasibility and accuracy of a novel, non-invasive method for continuously detecting and differentiating cardiorespiratory events in preterm infants on CPAP by integrating measurements of respiratory effort with respiratory acoustic monitoring.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Reliability of respiratory acoustics at detecting airflow compared to airflow measurements obtained from a pneumotachometer. | The airflow signal derived from the respiratory acoustic sensor will be compared with the airflow signal derived from the pneumotachometer. | 10 minutes (group 1) or 3 hours (groups 2 and 3) | |
Secondary | Reliability of the inertial measurement unit (IMU) at detecting respiratory efforts compared to Respiratory Inductance Plethysmography (RIP). | The chest wall movement signal derived from the respiratory acoustic sensor will be compared with the chest wall movement signal derived from RIP. | 3 hours (groups 2 and 3 only) | |
Secondary | Reliability of the inertial measurement unit (IMU) at detecting respiratory efforts compared to Transthoracic Impedance (TTI). | The chest wall movement signal derived from the respiratory acoustic sensor will be compared with the chest wall movement signal derived from TTI. | 3 hours (groups 2 and 3 only) |
