Flow sensors

  • Direct flow and pressure measurement proximal to the patient
  • Specially developed and approved for use with Hamilton Medical ventilators
  • Reduced risk of Ventilator Associated Pneumonia (VAP) due to single patient use

Every consumable is vital

Since 1983, the proximal flow sensor has been the centerpiece of all Hamilton Medical ventilators. It provides you with valuable data from the airway opening, and the whole ventilation process depends on these measurements and their accuracy. Precise volume, flow, and pressure data allow for better assessment of the patient’s lung condition. We offer single-use and autoclavable flow sensors for adult, pediatric and neonatal applications.

Proximal flow sensor measurement

Hamilton Medical ventilators measure flow and pressure close to the patient's airway. Studies have shown that tidal volumes for ventilated patients should be determined with a flow sensor placed at the endotracheal tube.1) Physically, the flow sensor is a thin membrane within a plastic housing.

Our physicians are very impressed with the disposable flow sensor, because there is no concern about cross contamination. They are single patient use and we don't have to worry about them being used again on another patient.
