Adaptive Ventilation Mode (AVM) is designed to maintain the clinician‑defined minimum minute volume, regardless of patient effort or spontaneous breathing. Using ideal body weight, the system calculates an appropriate tidal volume and rate intended to support minimal work of breathing when the patient is passive. Inspiratory pressure and machine rate automatically adjust to achieve the targeted minute volume, while the patient’s respiratory mechanics are continuously assessed on a breath‑by‑breath basis.
High-Frequency Oscillatory Ventilation (HFOV) provides a form of lung protective respiratory support by combining very high respiratory rates with exceptionally low tidal volumes using active inhalation and active exhalation. The 3100A and 3100B HFOV systems deliver this approach across neonatal, pediatric, and adult care settings.
The 3100A HFOV is indicated for ventilatory support and for the treatment of respiratory failure and barotrauma in neonates,1 while the 3100B HFOV is indicated for ventilatory support and treatment of select patients weighing 35 kilograms or more with acute respiratory failure.2 Supported by clinical and peer reviewed studies, the 3100 series offers a lung protective strategy that uses tidal volumes smaller than anatomical dead space, paired with rapid oscillatory rates.3
The ZOLL® Respiratory Knowledge Portal (RKP) displays ventilator information and offers insight that can support patient‑care decisions. It delivers timely display of retrospective ventilator data, paired with analytics that highlight operational trends and protocol‑execution. These dashboards give healthcare teams information that can help them plan, coordinate, and carry out ventilator‑management strategies, including weaning protocols.
RKP presents weaning‑protocol trends, care‑delivery efficiencies, and operational overviews that can inform process‑improvement efforts. Inefficiencies and variance from weaning protocols can lead to prolonged ventilator support and possibly even secondary lung injury.4 RKP dashboards help clinicians identify patient readiness to wean, execute wake up breathing initiatives, and inform clinicians to help avoid preventable secondary lung injury, including Ventilator Associated Events (VAE). Infographics help teams track improvement initiatives and spotlight areas that may require additional attention.
