BACKGROUND: We evaluate the clinical feasibility of spontaneous breathing on extracorporeal membrane oxygenation and the interactions between artificial and native lungs in patients bridged to lung transplant or with acute exacerbation of chronic obstructive pulmonary disease (COPD) or acute respiratory distress syndrome. METHODS: The clinical course of a total of 48 patients was analyzed. Twenty-three of 48 patients were enrolled in the prospective study (nine bridged to lung transplant, six COPD, and eight acute respiratory distress syndrome)...

Extracorporeal CO2-Removal (ECCO2R) is promoted with attributes like "safe" and "less invasive" compared to (high-flow) veno-venous ECMO-Systems. With our experience in coagulation disorders during ECMO-therapy with this observational study we for the first time prospectively evaluate hemolysis and coagulation disorders during ECCO2R. Eight consecutive patients with predominant hypercapnic respiratory failure were treated with the Hemolung® Respiratory Assist System (RAS) (Alung-Technologies, Pittsburg, USA)...

PURPOSE: Indirect calorimetry (IC) is the gold standard for measuring energy expenditure (EE). Due to O2 uptake and CO2 removal by both the extracorporeal lung support (ECLS) membrane and the lungs, a conventional IC is not feasible and no data available. Our MEEP (Measuring Energy Expenditure in ECLS Patients) protocol enables the determination of the REE in patients with ECLS, the comparison to patients without ECLS, and accuracy assessment of estimating equations. METHODS: In the MEEP protocol, a conventional IC is performed and extended by a calculation of the O2 uptake and the CO2 elimination by the ECLS membrane...

A new concept is presented for cooperative automation of mechanical ventilation and extracorporeal membrane oxygenation (ECMO) therapy for treatment of acute respiratory distress syndrome (ARDS). While mechanical ventilation is continuously optimized to promote lung protection, extracorporeal gas transfer rates are simultaneously adjusted to control oxygen supply and carbon dioxide removal using a robust patient-in-the-loop control system. In addition, the cooperative therapy management uses higher-level algorithms to adjust both therapeutic approaches...

Extracorporeal carbon dioxide removal (ECCO2R) is increasingly considered a viable therapeutic approach in the management of hypercapnic lung failure in order to avoid intubation or to allow lung-protective ventilator settings. This study aimed to analyze efficacy and safety of a minimal-invasive ECCO2R device, the Homburg lung. The Homburg lung is a pump-driven system for veno-venous ECCO2R with ¼" tubing and a 0.8 m surface oxygenator. Vascular access is usually established via a 19F/21cm bilumen cannula in the right internal jugular vein...

BACKGROUND: Recent advances in the technology of extracorporeal respiratory assist systems have led to a renewed interest in extracorporeal carbon dioxide removal (ECCOR). The Hemolung is a new, low-flow, venovenous, minimally invasive, partial ECCOR device that has recently been introduced to clinical practice to aid in avoiding invasive ventilation or to facilitate lung-protective ventilation. OBJECTIVE: We report our early experience on use, efficacy and safety of the Hemolung in three Australian intensive care units...

In acute exacerbations of COPD with acute hypercapnic respiratory failure and a pH 7.25 - 7.35, the initiation of non-invasive ventilation is the gold standard. However, absolute and relative contraindications have to be taken into account. The implementation of non-invasive ventilation in case of a severe respiratory acidosis necessitates a skilled therapeutic team and a close monitoring in order to avoid or perceive a NIV failure in time. In this case, the intubation and invasive mechanical ventilation is recommended...

PURPOSE OF REVIEW: Extracorporeal respiratory support in patients with acute respiratory distress syndrome is applied either as rescue maneuver for life-threatening hypoxemia or as a tool to reduce the harm of mechanical ventilation. Depending on the blood and gas flow, extracorporeal support may completely substitute the natural lung as a gas exchanger (high-flow venovenous bypass) or reduce the need for mechanical ventilation, enabling the removal of a fraction of the metabolically produced CO2...

We report a patient with chest trauma who was admitted to the ICU after surgery. As he fulfilled protocol-based criteria, he was extubated 7 days after admission. However, despite intermittent non-invasive ventilation, the patient had to be re-intubated on day 10 owing to progressive hypercapnia. We decided to support the patient with a mid-flow veno-venous extracorporeal carbon dioxide removal (ECCO2‑R) system instead of a tracheotomy. Sufficient CO2 removal was established with a blood flow of 1.5 l/min and the patient was successfully extubated within a few hours...

PURPOSE OF REVIEW: Ventilator-induced lung injury (VILI) can occur despite use of tidal volume (VT) limited to 6 ml/kg of predicted body weight, especially in patients with a smaller aerated compartment (i.e. the baby lung) in which, indeed, tidal ventilation takes place. Because respiratory system static compliance (CRS) is mostly affected by the volume of the baby lung, the ratio VT/CRS (i.e. the driving pressure, ΔP) may potentially help tailoring interventions on VT setting. RECENT FINDINGS: Driving pressure is the ventilatory variable most strongly associated with changes in survival and has been shown to be the key mediator of the effects of mechanical ventilation on outcome in the acute respiratory distress syndrome...

Total liquid ventilation (TLV) is an alternative treatment for severe lung injury. High tidal volume is usually required for TLV to maintain adequate CO2 clearance. However, high tidal volume may cause alveolar barotrauma. We aim to investigate the effect of low tidal volume on pulmonary inflammation in piglets with lung injury and under TLV. After the establishment of acute lung injury model by infusing lipopolysaccharide, 12 piglets were randomly divided into two groups, TLV with high tidal volume (25 mL/kg) or with low tidal volume (6 mL/kg) for 240 min, respectively...

REVIEW
Nikunj Bhatt, Erik Osborn
The use of extracorporeal support is expanding quickly in adult respiratory failure. Extracorporeal gas exchange is an accepted rescue therapy for severe acute respiratory distress syndrome (ARDS) in select patients. Extracorporeal carbon dioxide removal is also being investigated as a preventative, preemptive, and management platform in patients with respiratory failure other than severe ARDS. The non-ARDS patient population is much larger, so the potential for rapid growth is high. This article hopes to inform decisions about the use of extracorporeal support by increasing understanding concerning the past and present practice of extracorporeal gas exchange...

INTRODUCTION: Acute lung injuries are usually found in intensive care unit. The diffuse alveolar damage (DAD) is the associated histological pattern and the most severe end-stage of the disease. Organizing pneumonia (OP), for which corticosteroids are the reference therapy, can mimic DAD. While postponing the response to treatment, to limit mechanical ventilation side effects, extracorporeal membrane oxygene can be proposed. We present a case of a severe OP for which extracorporeal CO2 removal (ECCO2R) is used as a bridge to recovery under corticosteroid therapy...

A promising approach to facilitate protective mechanical ventilation is the use of extracorporeal CO2 removal techniques. Several strategies based on membrane gas exchangers have been developed. However, these techniques are still poorly available. The goal of this study was to assess the efficacy and safety of THAM infusion coupled to hemofiltration for the management of hypercapnic acidosis. A severe respiratory acidosis was induced in seven anesthetized pigs. Five of them were treated with THAM 8-mmol·kg(-1)·h(-1) coupled to hemofiltration (THAM+HF group) at 100 mL·kg(-1)·h(-1)...

Monitoring veno-venous extracorporeal membrane oxygenation (vvECMO) during 76 days of continuous support in a 42-years old patient with end-stage pulmonary disease, listed for double-lung transplantation. Applying a new monitor (Landing(®), Eurosets, Medolla, Italy) and describing how measured and calculated parameters can be used to understand the variable interdependency between artificial membrane lung (ML) and patient native lung (NL). During vvECMO, in order to understand how the respiratory function is shared between ML and NL, ideally we should obtain data about oxygen transfer and CO2 removal, both by ML and NL...

Patients with Idiopathic Pulmonary Fibrosis (IPF) requiring Invasive Mechanical Ventilation (IMV) following unsuccessful treatment with Non-Invasive Ventilation (NIV) have a high mortality rate. IMV is, moreover, an independent predictor of poor outcome during the post-transplantation period in patients on waiting lists for Lung Transplantation (LT). Here we describe the successful management of an IPF patient with acute respiratory failure (ARF) using a pump-assisted veno-venous system for extracorporeal CO2 removal (ECCO2R) (ProLUNG® system) as an alternative to endotracheal intubation (ETI) following NIV failure...

In the past the only option for the treatment of respiratory failure due to acute exacerbation of chronic obstructive pulmonary disease (aeCOPD) was invasive mechanical ventilation. In recent decades, the potential for extracorporeal carbon dioxide (CO2) removal has been realized. We review the various types of extracorporeal CO2 removal, outline the optimal use of these therapies for aeCOPD, and make suggestions for future controlled trials. We also describe the advantages and requirements for an ideal long-term ambulatory CO2 removal system for palliation of COPD...

INTRODUCTION: The aim of the study was to evaluate the feasibility and safety of avoiding invasive mechanical ventilation (IMV) by using extracorporeal CO2 removal (ECCO2R) in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) and acute hypercapnic respiratory failure refractory to noninvasive ventilation (NIV). METHODS: Case-control study. Patients with acute hypercapnic respiratory failure refractory to NIV being treated with a pump-driven veno-venous ECCO2R system (iLA-Activve(®); Novalung, Heilbronn, Germany) were prospectively observed in five European intensive care units (ICU)...
