Background: Between 4 to 45 % of intensive care patients suffer from prolonged ventilator dependence. Due to impeded weaning, verbal communication is impossible. The tracheal cannula affects breathing and swallowing. The Passy Muir speaking valve (PMV) allows patients on ventilators to speak. It counteracts pharyngeal as well as laryngeal desensitization and prevents an insufficient swallowing reflex. Aim and methods: To implement the PMV, we conducted a multiprofessional practice- and quality development project. The objective was to ensure safe swallowing and communicating for ventilated patients with tracheostoma. Results: Intensive care nurses, doctors and physiotherapists assessed patient safety as being high. In nine patients with 51 PMV applications, we observed three undesirable events in terms of dyspnea and oxygen desaturation. On one occasion, it was necessary to remove the PMV. Conclusion: A combination of mandatory training for the entire treatment team, presence of two professionals during PMV application, and a newly developed guiding document resulted in a high level of patient safety. By means of PMV, ventilated intensive care patients are able to communicate verbally and to swallow better. Complications can be identified early and solved effectively.
