Abstract
Abstract
The modification of membrane oxygenators to minimize protein adsorption onto the surface is often accompanied by the loss of membrane performance. This study aims to explore polyethersulfone (PES) as a new material for membrane oxygenator applications and to assess its potentials. Accordingly, different modification techniques are applied to improve surface properties of PES membranes. To achieve this goal, two separate modification methods including incorporation of TiO2 into the membrane matrix as well as grafting polyethylene glycol (PEG) through oxygen plasma treatment are developed and the effects are examined. The results reveal that protein adsorption to the nanocomposite membrane containing 0.50 wt. % TiO2 and the grafted membrane decreased by 47 and 31%, respectively. In terms of performance, permeability and oxygen transfer rate of all modified membranes exceeded 808 GPU and 2.7 × 10−4 mol·m−2·s−1, respectively. Contact angle analysis revealed signs of hydrophilicity enhancement of membranes after modifications. The findings suggest that upon proper modifications, membranes based on PES could be considered as promising candidates for membrane oxygenator applications and deserves further investigations.

Abstract
ABSTRACT Since extracorporeal membrane oxygenator (ECMO) has been utilized to save countless lives by providing continuous extracorporeal breathing and circulation to patients with severe cardiopulmonary failure. In particular, it has played an important role during the COVID-19 epidemic. One of the important composites of ECMO is membrane oxygenator, and the core composite of the membrane oxygenator is hollow fiber membrane, which is not only a place for blood oxygenation, but also is a barrier between the blood and gas side. However, the formation of blood clots in the oxygenator is a key problem in the using process. According to the study of the mechanism of thrombosis generation, it was found that improving the hemocompatibility is an efficient approach to reduce thrombus formation by modifying the surface of materials. In this review, the corresponding modification methods (surface property regulation, anticoagulant grafting, and bio-interface design) of hollow fiber membranes in ECMO are classified and discussed, and then, the research status and development prospects are summarized.

Abstract
Gas transfer through hollow fiber membranes (HFMs) can be increased via fiber oscillation. Prior work, however, does not directly translate to present-day, full-scale artificial lungs. This in vitro study characterized the effects of HFM oscillations on oxygenation and hemolysis for a pediatric-sized HFM bundle. Effects of oscillation stroke length (2-10 mm) and frequency (1-25 Hz) on oxygen transfer were measured according to established standards. The normalized index of hemolysis was measured for select conditions. All measurements were performed at a 2.5 L min-1 blood flow rate. A lumped parameter model was used to predict oscillation-induced blood flow and elucidate the effects of system parameters on oxygenation. Oxygen transfer increased during oscillations, reaching a maximum oxygenation efficiency of 510 mL min-1 m-2 (97% enhancement relative to no oscillation). Enhancement magnitudes matched well with model-predicted trends and were dependent on stroke length, frequency, and physical system parameters. A 40% oxygenation enhancement was achieved without significant hemolysis increase. At a constant enhancement magnitude, a larger oscillation frequency resulted in increased hemolysis. In conclusion, HFM oscillation is a feasible approach to increasing artificial lung gas transfer efficiency. The optimal design for maximizing efficiency at small fiber displacements should minimize bundle resistance and housing compliance.

Abstract
Polyethylene glycol (PEG) and heparin (Hep) were grafted onto polysulfone (PSF) membrane by plasma-induced surface modification to prepare PSF-PEG-Hep membranes used for artificial lung. The effects of plasma treatment parameters, including power, gas type, gas flow rate, and treatment time, were investigated, and different PEG chains were bonded covalently onto the surface in the postplasma grafting process. Membrane surfaces were characterized by water contact angle, PEG grafting degree, attenuated total reflectance-Fourier transform infrared spectroscopy, ultraviolet-visible spectrophotometry, X-ray photoelectron spectroscopy, critical water permeability pressure, and scanning electron microscopy. Protein adsorption, platelet adhesion, and coagulation tests showed significant improvement in the hemocompatibility of PSF-PEG-Hep membranes compared to pristine PSF membrane. Gas exchange tests through PSF-PEG6000-Hep membrane showed that when the flow rate of porcine blood reached 5.0 L/min, the permeation fluxes of O2 and CO2 reached 192.6 and 166.9 mL/min, respectively, which were close to the gas exchange capacity of a commercial membrane oxygenator. © 2016 Wiley Periodicals, Inc.

Abstract
Blood oxygenation is the main performance characteristic of capillary membrane oxygenators (CMOs). Handling of natural blood in in vitro investigations of CMOs is quite complex and time-consuming. Since the conventional blood analog fluids (e.g. water/glycerol) lack a substance with an affinity to capture oxygen comparable to hemoglobin's affinity, in this study a novel approach using modified sulfite solution is proposed to address this challenge. The solution comprises sodium sulfite as a component, simulating the role of hemoglobin in blood oxygenation. This approach is validated by OTR (oxygen transfer rate) measured using native porcine blood, in two types of commercially available CMOs. Consequently, the number of complicated natural blood investigations in the evolution procedure of newly developed oxygenators would considerably decrease. Moreover, the reassessing of failed devices, in clinics, would be performed more precisely using a modified sulfite solution than simple water/glycerol testing.

Abstract
Intravascular oxidation is a respiratory assist method used to treat acute respiratory distress syndrome (ARDS). However intravascular oxidation through higher gas exchange is needed for successful clinical applications. In this study, an attempt was made to improve the gas exchange of an intravascular lung assist device by decreasing the level of damage to the blood through the microencapsulation of hemoglobin. The results showed that a hemosome 0.8 microm in diameter could be produced by microencapsulating the hemoglobin extracted from fresh bovine blood with the phospholipids extracted from egg yolk. The oxygen saturation curve of hemosome was S-shaped, which is similar to that found in normal blood, and the P50 was 24 mmHg. The oxygen saturation in the mixed solution of hemosome and blood at a 1:4 (v/v%) ratio was similar to that of normal blood. The gas exchange of the blood-hemosome mixed solution was more effective than whole blood. Therefore, the hemosome solution is expected to improve oxygen transfer.
