SOLUTIONS FOR VENTILATORS

Honeywell airflow sensors (see Table 1) are designed to measure the flow of air, oxygen and nitrous oxide and monitor the patient’s breathing. They may be used so that the desired mixture, as set by the doctor, is delivered to the patient. The total mixture that is delivered to the patient is also measured and displayed on the ventilator panel.
