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: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
