Blowing up diseased lungs could save lives

25.11.2002


Patients with acute respiratory distress syndrome (ARDS) rely on mechanical ventilation to breathe, however routine suctioning to remove debris that may be blocking their airways can cause lung tissue to collapse. New research published in Critical Care explains how a new technique involving the re-inflation of lungs after suctioning can lead to a marked improvement in the condition of patients with acute respiratory distress syndrome.



Acute respiratory distress syndrome is a devastating inflammatory lung disease that affects around 150,000 people each year in the US alone. The syndrome is characterized by fluid accumulation and swelling in the lungs, followed by respiratory failure that can often be fatal.

An ARDS patient relies on mechanical ventilation to breathe, but if their airway becomes fully or even partially blocked it can lead to several serious physiological abnormalities and even death. Unfortunately, the use of suctioning to remove obstruction can lead to the collapse of lung tissues making it more difficult for a patient to get oxygen into their bodies.


In an effort to improve the care of patients with ARDS, Thomas Dyhr and colleagues have investigated the effect of re-inflating the lungs after suctioning. This re-inflation technique is known as a lung recruitment manoeuvre as it "recruits" previously collapsed lung tissue to help the patient breathe more easily

Dyhr and colleagues conducted a small randomised controlled study of eight patients with ARDS to test whether inflating the lung twice after suctioning was beneficial. The lung volume and the concentration of oxygen in arterial blood was monitored to establish the effects of the treatment.

The results showed that re-inflation was able to reduce the adverse effects of suctioning by increasing both the lung volume and the level of oxygen in arterial blood.

The researchers recognise this is only a small preliminary study, but they are hopeful that this re-inflation technique could have a positive impact on the recovery of patients with ARDS.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
