Respironics BiPAP How do I guarantee ventilation efficiency ? How do I ensure tolerance to ventilation ? How do I know the system is reliable? Etc… Efficiency Comfort Safety Versatility Prediction
Respironics Technology and Know How How do I achieve an optimised patient/ventilator Synchronisation? How do I guarantee ventilation Efficiency? Efficiency Comfort Safety Versatility Prediction
Respironics Technology and Know-How AVAPSTM • Late 80’s, Respironics first introduced BiPAP technology and Auto-TRAK Algorithm for better patient/ventilator synchronization • Chest 1997 : “Performance Characteristics of Bilevel Pressure Ventilators” • AJRCCM2001 : “Noninvasive Ventilator Triggering in Chronic Obstructive Pulmonary Disease” • Chest2005 : “Performance Characteristics of 10 Home Mechanical Ventilators in Pressure-Support Mode” • 2003: Respironics introduced AVAPS for improved ventilation comfort and efficiency without compromise
Blower Flow Pressure Patient Circuit Air Filter AirflowSensor Proportional Valve Ambient Air Exhaust Respironics BiPAP Technology Respironics BiPAP Blower only • Blower works at a constant speed The blower inertia does not affect patient ventilation • The valve controls the flow provided by the blower Response time close to 0 : able to provide high patient breath rate and high rise time, short fall time Responds to extra flow demand (225LPM at 25cmH2O) Compensates for most leaks Reduces respiratory work
Respironics BiPAP VentilatorsBiPAP Harmony and BiPAP Synchrony • Same Technology: BiPAP • Blower works at a constant speed • The valve controls the flow provided by the blower • Digital Auto-TRAK Sensitivity • Same Platform: • Integrated heated humidifier • SmartCard • Compatible with both Encore Pro software and Stardust II polygraph • Small and light: • 1,8 Kg • 24 x 17 x 11 = 4,5 L
« Unlike manually controlled triggers, Auto-TRAK does the work for you » • Automatic inspiratory trigger and expiratory cycle • Leak compensation over 60LPM • Leak estimation to calculate Vte at 15% accuracy Characteristics Advantages • Efficient Ventilation: Leaks are all compensated. Trigger thresholds automatically adjust according to the changes in leaks and patient respiratory mechanics • Easy Ventilation: No trigger adjustments are required • Safe Ventilation: Alarms & monitoring of Vte, MinVent
Digital Auto-TRAK Algorithm • Inspiration: when the patient makes an effort to inspire, the flow naturally increases • Expiration: when the patient makes an effort to expire, the flow naturally decreases Flow Shape signal: Delayed waveform crossing patient flow in case of flow direction changes Detects an accumulated 6ml volume above the base line
Digital Auto-TRAK Algorithm • Spontaneous Expiratory Threshold: electronic signals that rises in proportion of tidal volume • Flow Reversal: allows detection of excessive mouth leak. If the flow increases by more than 10% of the peak flow in a short period of time then switch to EPAP • Safety Feature: inspiratory time cannot exceed 3 seconds
Digital Auto-TRAKTM Sensitivity « A proven technology » “Patient-ventilator synchrony is a key to the success of long-term Home NIV as dysynchrony causes patient intolerance” Chest2005 : “Performance Characteristics of 10 Home Mechanical Ventilators in Pressure-Support Mode”

AVAPSTM Feature Variation of 1cmH2O maximum per minute PS ±ΔP PS Ensure Averaged Vt • AVAPS available on S, S/T, PC and T modes • IPAP automatically adjusts from breath to breath to ensure an averaged Vt • Settings: IPAPmin, IPAPmax and Target Vt
AVAPSTM Suggested Settings • Set the Target Tidal Volume To the displayed patient tidal volume when ventilated on S/T mode or To 8ml/kg of ideal weight and adjust depending on pathology, patient tolerance and clinical outcome Set IPAP Limits IPAP max = 25 to 30 cmH2Odepending on patient pathology and IPAP min = EPAP + 4 cmH2O
Respironics Alarms • Disconnection: OFF, 15, 60 sec. • High flow rate and small pressure • Low minute Ventilation: from 0 to 99 LPM • Apnea alarm: OFF, 10, 20, 30 sec. • Low tidal Volume (AVAPS only): OFF (0) / ON (1) • When the target tidal volume is not reached whereas the IPAP is at the set IPAP max level Efficiency Comfort Safety Versatility Prediction
