3100 A
|
|
|
The 3100A High Frequency Oscillatory Ventilator was first approved for use in 1991 and is the only HFV approved for early intervention in the treatment of neonatal respiratory failure. |
|
The scope of application was broadened in 1995 to include selected pediatric patients failing conventional mechanical ventilation. The 3100A provides the ultimate in lung protection by inflating the lung with a continuous distending pressure and superimposing very small pressure and volume swings. |
|
The 3100A HFOV is the standard of care in more than 90% of Level III nurseries in the US and 75% of the Pediatric Intensive Care Units, and there are over 3000A ventilators in use worldwide. |
|
The Alliance of Children's Hospitals, Inc. has awarded their prestigious "Seal of Acceptance" to VIASYS for the 3100A HFOV. |

3100 B
|
|
|
The 3100B HFOV signals the arrival of the next generation of High Frequency Oscillatory Ventilators. |
|
The 3100B HFOV is approved for the treatment of acute respiratory failure in adults and large children weighing more than 35 kilograms. |
|
The 3100B allows the application of continuous distending pressures up to 55 cmH2O to recruit and normalize lung architecture while ventilating the patient with near deadspace tidal volumes for the ultimate in low stretch lung protection. |
|
A randomized, controlled trial comparing HFOV and conventional ventilation in an adult patient population with severe ARDS demonstrated that HFOV is both safe and effective and resulted in a 29% relative reduction in mortality. |

Did you know....
Bias Flow - One flow fits all?
Many clinicians set the bias flow to 20 LPM for the calibration procedure and then leave it at that setting. The bias flow setting
along with the resistance of the control valve determines the PAW. Increasing the bias flow increases the
PAW and conversely decreasing bias flow will decrease the PAW.
Ventilation is effected by the bias flow. Too little flow through the circuit may result in an elevated PCO2 due to
insufficient wash out of exhaled gas. Too much flow may also cause PCO2 to rise. The reverse stroke of the piston is
responsible for active exhalation. When there is too much flow the reverse stroke may only remove the gas from the circuit.
If an infant is breathing against a high bias flow the resistance can cause them to become fatigued. By lowering the bias flow the infants
WOB will decrease and it will allow the clinician to set a lower PAW. In neonatal applications, flows of 10-15 LPM are
generally sufficient to eliminate exhaled CO2 in the circuit and generate the desired PAW. Many
NICU's wean their infants from HFOV directly to NCAP or supplemental oxygen.
In practice the following flow settings are usually appropriate. |
