Extreme exertion does not impair the quality of CPR given by lifeguards

14.06.2011
Swim centre personnel and lifeguards have higher stamina and carry out cardiopulmonary resuscitation more effectively than personnel in the emergency healthcare services, even though they have undergone extreme exertion. Their life-saving efforts may be crucial while waiting for an ambulance. This is the conclusion of research carried out at the University of Gothenburg, Sweden.

Swim centre personnel and lifeguards are trained in, and regularly practice, rescue from water and cardiopulmonary resuscitation, CPR. A study has been carried out with the aid of the Swedish Life Saving Association and Livräddarna Tylösand in order to describe the rescue process and how effectively lifeguards carry out CPR during a rescue from the sea. The study was recently presented by scientist and ambulance nurse Andreas Claesson of the Sahlgrenska Academy/University of Gothenburg at the "World Congress on Drowning Prevention" in Vietnam, 10-13 May.

The study involved 40 surf lifeguards, 26 men and 14 women, who participated in two tests. These were later compared with each other. On the first day, the participants carried out CPR for 10 minutes alone on a manikin. Various parameters were measured, including the depth and frequency of chest compression and the volume of ventilation. On the second day, the participants carried out a simulated surf rescue of an unconscious person of weight 80 kg, 100 metres from the shore with the aid of a special type of lifebuoy known as a "torpedo" buoy. The complete rescue procedure was recorded, and the lifeguard again carried out CPR for 10 minutes on a manikin on the beach.

"The most important finding was that the extreme exertion during the surf rescue did not affect the capacity of the lifeguards to carry out CPR. This was high during the complete procedure and was just as effective during the 10 minutes independently of whether the lifeguard had previously carried out exertion. The results are, of course, difficult to transfer to emergency healthcare, but the comparison is very interesting. We exchange the person carrying out chest compression every two minutes in order to ensure that the CPR is carried out in the best possible manner", says Andreas Claesson.

Andreas Claesson's previous studies of CPR have shown that it takes an average of 15 minutes from an alarm about drowning until arrival of an ambulance in Sweden.

"The first 15 minutes after a drowning accident are crucial. It is vital that someone at the scene calls an ambulance and immediately starts cardiopulmonary resuscitation without interruption, while waiting for the ambulance to arrive. Many precious minutes may be lost if the people at the scene are not trained in CPR, and this is not started until the ambulance arrives", says Andreas Claesson.

He thinks that it should be taken for granted that lifeguards and swim centre personnel are present at beaches and in swimming halls, since studies have shown that the probability of surviving is much higher if these personnel are on site and can react immediately, while waiting for the ambulance.

"However, the situation in reality is different, and that's why I believe that all who want to and are able to should learn CPR and basic lifesaving skills, such that they can provide aid in the event of an emergency", says Andreas Claesson.

Cardiopulmonary Resuscitation, CPR
Around 10,000 people in Sweden experience unexpected cardiac arrest each year. Approximately 250 people drown each year, and the rescue services, police and ambulance are always alerted in cases of drowning, no matter what the cause. Alarm without delay, immediate rescue, and immediate CPR in order to restore respiration and blood flow all increase the chances of survival. CPR involves the rescuer providing mouth-to-mouth resuscitation, which supplies oxygen to the blood, and compression of the chest, which pumps the blood out to the tissues of the body and to the blood vessels of the brain and heart.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
