While the majority of COPD patients have EFL, care teams have never had a COPD NIV ventilation therapy that dynamically and automatically targets EFL. BiPAP A40 EFL is the first and only NIV therapy precision-crafted to abolish EFL in hypercapnic COPD patients. It screens, detects and auto-optimizes pressure – to treat comfortably and redefine what is possible in managing COPD.

Screen with simplicity
Identify EFL at the point of care

Identify EFL at the point of care

BiPAP A40 EFL's (Expiratory Flow Limitation) screening system is a simple, convenient and noninvasive way to screen COPD patients for EFL right in the office, clinic or ward. It is the only ventilation system that identifies EFL during quiet breathing and is more accurate than any alternative method – so you can uncover EFL in all of your hypercapnic COPD patients.¹,²,³
Detect EFL - Breath by Breath
Provide timely, targeted therapy

Provide timely, targeted therapy

Identify hypercapnic COPD patients with EFL – and intervene with a targeted therapy in a timely manner. This can help you put patients on the right path to sustainable treatment.
Auto-titrate each breath
Reduce patients' work of breathing

Reduce patients' work of breathing

BiPAP A40 EFL helps enable pulmonologists to enhance gas exchange, diminish patient-ventilator asynchrony,3* and stabilize the lower airways by dynamically and automatically adjusting therapy to the optimal expiratory pressure (EPAP). This helps support adherence and patients can receive comfortable, sustainable therapy at home.
Optimal pressure therapy
Supports long-term compliance

Supports long-term compliance

BiPAP A40 EFL auto-titrates prescription settings to the lowest possible EPAP.³ This helps support adherence so patients receive comfortable, sustainable therapy at home.
Streamline diagnosis
Enhance and coordinate care

Enhance and coordinate care

BiPAP A40 Pro auto-integrates with sleep lab and home diagnostic systems as well as with Philips Respironics Care Orchestrator platform. It delivers patient data directly from the device to your point of care and patient management care teams.⁴ The resulting collaboration can lead to informed clinical decisions that raise the quality of care to new heights.
Stay connected
Remotely monitor and manage therapy

Remotely monitor and manage therapy

BiPAP A40 EFL connects to Philips Care Orchestrator to enable more targeted and efficient patient management. It turns longitudinal data into actionable insights, empowers care providers to prioritize interventions and lets your team anticipate and resolve most patient concerns remotely. With Care Orchestrator, you have more actionable treatment information in your hands.
Visually manage leak
Visual leak management

Visual leak management

BiPAP A40 EFL provides clinicians and patients the ability to visually understand the quality of their total circuit leak to support initial mask fitting and circuit setup as well as giving patients the confidence that their circuit and mask are delivering their daily personalized ventilation therapy.
Proven reliability
Confidence in quality, always

Confidence in quality, always

BiPAP A40 EFL helps reduce the cost and labor of managing patients compared to competitive devices. It does not require periodic or preventative device maintenance or battery replacement. Further, you have the assurance that BiPAP A40 EFL leverages the same BiPAP A40 and A30 quality platform, with 97.8% of current patients are complaint free.
