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: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
