In the literature, studies examining the effect of virtual reality application on physiological parameters and anxiety during inhalation therapy, which is frequently used in children, are quite limited. Therefore, this study will be conducted to determine the effect of virtual reality goggles and distraction cards on physiological parameters and anxiety in patients receiving inhalation therapy.

According to the Global Sustainable Development Report, virtual reality (VR) is one of the issues that are expected to bring about major innovations in applications, and this concept was first used by Jaron Lanier towards the end of the 1980s. VR enables computer-generated three-dimensional images and animations to interact with these objects in the environment while giving the feeling of being in a real environment in people's minds with technological tools. The purpose of VR is to make the user believe that they are in the computer-generated environment as much as possible. According to the Turkish Language Association, it is defined as 'a three-dimensional environment created by giving imitations of real environments in a virtual sphere that provides 360-degree vision using artificial intelligence, where unreal environments can be experienced as real, solving complex problems, information transfer, entertainment, etc. It is used for purposes'. Virtual reality technology is used in the field of health as a method of distraction that provides various visual, auditory, tactile and olfactory stimuli and real perceptual stimuli and is applied in many processes related to care and treatment in the health sector, especially in children. Technologies used in health care services accelerate the recovery of patients and provide ease of operation to health professionals. Children encounter many acute or chronic diseases during their developmental period. Hospitalisation as a result of these diseases is complicated and stressful for children and their families and can cause fear, anxiety and anxiety in children. Medical procedures encountered during hospitalisation are the main source of fear for children. They may experience anger, helplessness and anxiety due to reasons such as unfamiliar environment, change in the routine of the child, different sound, light, tools and equipment, unfamiliar people, painful painful procedures, being away from family and friends, loss of control, activity limitation, communication difficulties, presence of other children crying. The use of technology in preparation for or during medical procedures is an effective method in providing anxiety and comfort. Virtual reality is used in injection applications, intravenous interventions, burn dressings and postoperative pain experiences and physiological parameters in children and adolescents. Kurban and Şener investigated the effect of virtual reality goggles applied during vaccination on pain and anxiety in children aged 6-12 years and reported that the VR group had significantly lower pain and anxiety scores. In a systematic review conducted by Nacaroğlu et al. to examine the effect of virtual reality applications on pain and anxiety perception during invasive and painful procedures in school-age children in Turkey, it was reported that VR application positively affected pain and anxiety. In the study conducted by Okay and Okay in 2024 to examine the effect of virtual reality goggles on physiological parameters during inhalation therapy in children aged 2-5 years, it was observed that children watching videos with virtual reality goggles decreased the number of respirations and heart rate per minute, increased oxygen saturation values, decreased crying time and increased treatment efficacy. At the same time, although each child has different interests, it was observed that children experienced less fear and anxiety in studies where calming ocean videos were watched. Respiratory system diseases are frequently seen in childhood and constitute a significant portion of hospital admissions. Respiratory system diseases are an important cause of mortality and morbidity all over the world, a serious public health problem in developed and developing countries, and constitute 8.2% of all disabilities. According to WHO, respiratory tract infections are the most common cause of mortality in children under five years of age and are responsible for 19% of child deaths. According to the data of Turkish Statistical Institute (TurkStat), upper respiratory tract infections (URTI) are the most common disease in the 0-14 age range in our country. Inhalation therapy, which is one of the important methods in the management of respiratory system diseases, is frequently used in paediatric patients to relieve bronchospasm and to relieve the airway by delivering drug particles to the extreme lobes of the lungs. Inhalation therapy is frequently preferred because of its rapid effect, the absence of the need for an intravenous catheter and thus the absence of injection-related pain, the direct effect of the drug on the desired area (lungs), the low side effects on other systems, and the fact that it can be used at any age. Although inhalation treatment with mask is an easy intervention, it is an application that causes fear and anxiety in children. Success in treatment is ensured by the compliance of the child and the family. Children generally do not accept mask treatment and show crying and refusal behaviour. Since the crying of the child during the treatment will reduce intrapulmonary storage, the amount of drug reaching the lungs will decrease and may adversely affect the treatment. At the same time, respiratory distress experienced by children causes anxiety, dyspnoea and increase in respiratory rate. For these reasons, children receiving inhalation therapy should be calm. In order to provide effective inhalation therapy, it is recommended to use evidence-based distraction methods. There are many methods used to divert attention. Some of these are; watching cartoons, hypnotherapy, playing with toys, using virtual reality goggles, music therapy, play therapy, using kaleidoscope and using distraction cards. The method used to divert the attention of paediatric patients should affect both visual and auditory senses and at the same time be appropriate for the development of the child. The aim of the paediatric nurse is to protect and improve the mental, physical, social and spiritual health of the child and to provide holistic care for treatment in the presence of disease. In the literature, studies examining the effect of virtual reality application on physiological parameters and anxiety during inhalation therapy, which is frequently used in children, are quite limited. Therefore, this study will be conducted to determine the effect of virtual reality goggles and distraction cards on physiological parameters and anxiety in patients receiving inhalation therapy.

I can share it when necessary, I'm not thinking about it right now.
