Clinical Need

Respiratory depression due to residual anesthetics may cause brain damage or death in a post-anesthesia care unit (PACU). Growing use of opioid and Propofol increases the risk of respiratory depression and arrest. Continuous monitoring of tidal volume and minute ventilation is needed to ensure better care for these non-intubated patients as well as patients with obesity hypoventilation syndrome (OHS), neuromuscular diseases, and chronic obstructive pulmonary disease (COPD).

Current Practices

Spirometry and capnography require face masks or nasal cannulas. Capnography and SpO2 are slow to detect respiratory depression. Impedance pneumography lacks accuracy.


BiLab provides a method to quantify how much air fills the lungs in every breath. Using a multi-channel impedance plesthysmography technology, noninvasive real-time ventilation monitoring is possible for patients with respiratory depression, OHS, neuromuscular diseases, and COPD. Using electrodes around the chest, BiLab’s hypoventilation monitor provides breath-by-breath tidal volume, respiration rate, and minute ventilation.
