ExSpiron is a bedside respiratory monitor for non-ventilated patients, such as those in post-op recovery or ICUs. The monitor noninvasively provides minute ventilation data in a simple bedside monitor. In addition, the ExSpiron provides respiratory rate and tidal volume so the care team can instantly see all three metrics as well as trend graphs over time. ExSpiron does not require a specialist and may easily be used by nurses, physicians and other clinicians simply by applying a noninvasive chest sensor. ExSpiron can be used across anesthesia/OR, post-op recovery and intensive care units.
