Rapid Assistance Circulatory arrest, respiratory disease, poisoning and severe trauma – thanks to emergency ventilation from Emergency Medical Service professionals, every day thousands of people get a second chance at life. Rescue teams are often under a lot of time pressure. Stress and significant physical and psychological strain are part of their everyday working lives. After all, when it is a matter of life and death, every move must be spot on. If a patient stops breathing or there is a risk of the respiratory muscles becoming fatigued, breathing must be managed either manually with a...

Patient Safety Risks of bag-valve-mask ventilation Do you prefer to use a resuscitator and mask over a ventilator? Do you feel more confident when you are able to take the patient “into your own hands”? Studies confirm that bag-valve-mask ventilation often poses more risks than benefits. This is because it is technically demanding and requires a lot of skill and training. Even experienced EMS professionals are not always able to ventilate patients exactly as prescribed by international guidelines1. These demand constant ventilation volumes and the avoidance of pressure peaks in the airways....

Risk: Overinflation of the Stomach Preventing aspiration Ventilation with a resuscitator and mask is not always sufficient. With mechanical ventilation this risk is reduced. This was This is why too much volume is often delivered. This is not confirmed by a study on a manikin with simulated circulatory without its risks: Overpressure rapidly builds up and the risk of arrest4: Whilst the lung tidal volume was comparable, the stomach stomach overinflation increases. This can lead to regurgitation tidal volume with mechanical ventilation was considerably less and aspiration of the stomach...

Risk: Lung Damage Avoiding pressure peaks Excessively high ventilation pressures can lead to overinflation would generate5. Moreover, EMS professionals use different of the pulmonary alveoli and trigger barotrauma or volutrauma. techniques – and thus apply more or less pressure to the bag. Given the lack of monitoring, there is no pressure control with With ventilators, on the other hand, there is integrated pressure manual ventilation. Pressure is delivered by instinct. This results, limitation to avoid pressure peaks. in part, in considerably higher peak pressures than a ventilator...

Risk: Hyperventilation Maintaining the right rate Hyperventilation is an everyday challenge for all EMS professionals. This is hardly surprising given that overly high ventilation rates reduce the likelihood of survival. This was confirmed by a study of out-of-hospital emergencies with cardiac arrest and manual bag ventilation conducted in the USA6. The EMS professionals hyperventilated almost all patients – with fatal consequences. On the back of this, scientists simulated this observation on pigs suffering from cardiovascular failure. The result: Almost all animals survived ventilation...

Blood gases “out of kilter” During transportation in particular it is difficult to maintain the right ventilation rate. According to a study, this can be demonstrated with the blood gas values7: In the case of manually ventilated patients the CO2 partial pressure fell, the pH value increased and patients experienced respiratory alkalosis, yet with mechanically ventilated patients, the acid-base balance essentially remained stable. Vasodilation possible in the body Reduced intercerebral circulation (resulting in hypoxia of the brain) Shift of the O2 binding curve to the left Reduced tissue...

Risk: Airway Access Intubation is not absolutely necessary There is no doubt that intubation is the gold standard with mechanical ventilation as it protects against aspiration. However, safe intubation in preclinical treatment is associated with risks and failed attempts with extended hypoxia times are not the exception. This is why many EMS professionals continue to opt for alternatives. If you wish to avoid intubation, but still desire controlled ventilation, you can also use our ventilators with less invasive techniques such as a laryngeal mask, laryngeal tube or ventilation mask....

Patient Safety In contrast to manual ventilation, mechanical ventilation offers key advantages, particularly with regard to patient safety : 8 • f the patient is ventilated using a mask, the EMS professional I can hold the head in a correct axial position with both hands In terms of patient transport, too, mechanical ventilation beats manual ventilation. This was confirmed by a comparative study: With manual ventilation the ventilation parameters of intubated patients during intra-clinic transportation fluctuated more significantly than with mechanical ventilation9. Moreover, • he risk of...

Free your head and your hands Not only patients but also you as an EMS professional benefit from mechanical ventilation. After all, ventilators offer enhanced safety: Visual and acoustic alarms, clearly visible measurement and setting parameters as well as constant ventilation parameters ensure the guideline-compliant and consistent ventilation of patients. Some of the devices from WEINMANN Emergency also feature special functions such as voice prompts, metronome and CPR1 and RSI2 modes. With the MEDUtrigger individual mechanical breaths can be triggered manually on the mask. This enables...

<& Ventilators Improved control with ventilators Ventilators guarantee the right ventilation rate and keep this constant. Depending on the ventilation form, the ventilation pressure/ volume are also constant or are measured and displayed. This means hyperventilation and hypoventilation are avoided. Hypoventilation is often a consequence of bag-valve-mask ventilation as the mask is not positioned tightly on the face with just one hand. MEDUMAT Easy CPR With MEDUMAT Easy CPR a device has been developed specifically for emergency ventilation during and after resuscitation. An example of this...
