Description | |||
| Brief Description: | The Flow-byÔ 2.0 Flow Triggering System flow triggers all patient-initiated breaths, immediately supplies gas to the patient, provides supplemental flow of up to 180 Lpm on spontaneous breaths, and measures breath-to-breath volumes while letting all alarms and monitoring remain active. | ||
Characteristics | |||
| Operating Range of Controls: | Base flow: from 5 to 20 Lpm; Flow sensitivity: between 1 and 15 Lpm with a default pressure sensitivity of 3 cmH2O | ||
Specifications | |||
| Alarms: | All alarms remain active except that the exhalation valve leak alarm is deactivated during spontaneous breathing. | ||
| Other Specifications: | Flow rate for spontaneous breaths: Determined by patient effort and sensed by pressure feedback. The flow rate delivered is the amount needed to maintain pressure in the patient circuit at baseline pressure or at the selected level of pressure support. The ventilator can deliver up to 180 Lpm (120 for ventilators with compressors). For non-pressure supported spontaneous breaths, exhalation is detected when Vexh exceeds Vdel by 2 Lpm. For pressure supported breaths, exhalation is detected when patient pressure flow drops below 5 Lpm or inspiratory time is greater than 5 seconds. Base flow is then temporarily lowered to 5 Lpm to reduce expiratory resistance. | ||
