Ventilated each year
Mechanical ventilation is not an edge case. It is a daily, global decision environment where better functional data can matter at scale.
See the lung at the bedside
InspiWave™ adds continuous, noninvasive heart-lung measurement to the ventilated patient, revealing physiology conventional monitors can only imply.
Ventilation decisions need a clearer view.
Mechanical ventilation is one of critical care's most consequential interventions. It touches millions of patients, carries steep risk when ventilation is prolonged, and turns every additional day into a compounding clinical and system burden.
Mortality signal
When ventilation is prolonged, the stakes rise quickly. Earlier insight can help clinicians understand whether the lung is truly responding.
Per ICU patient per day
Each extra day compounds patient risk, staffing load, bed pressure, and cost. The need for clearer decisions is clinical and operational.
InspiWave turns ventilation from inference into measurement.
InspiWave adds a low-concentration inspired tracer signal and reads the exhaled response to reveal previously absent bedside measures of lung volume, cardiac output, dead space, and functional ventilatory distribution.
Effective lung volume
How much lung is available for gas exchange, so recruitment can be judged by usable volume.
Dead space
How much of each breath is not participating in exchange, revealing wasted ventilation and mismatch.
Effective lung volume
890 mLCardiac Output
5.2 L/minDead space
142 mLVentilatory distribution
68 %Cardiac Output
How heart-lung function responds as ventilation changes, measured continuously at the bedside.
Ventilatory distribution
How evenly gas reaches the lung, surfacing functional changes that pressure and flow only imply.
Together, these four measurements translate tracer-gas physiology into continuous bedside insight, giving ICU and OR teams functional data to support lung-protective ventilation decisions and reduce avoidable uncertainty.
