Vital Signs Monitoring

In Ghana, and many other low and middle income countries in Africa, manual vital signs monitoring is the prevalent mode of vital signs monitoring because continuous bedside monitors are non-functional. This lack of continuous vital signs monitoring may result in missed opportunities to catch physiologic deterioration. The investigators propose to develop a dashboard that is based on the Garmin Venu 3, a consumer wearable device that reliably measures heart rate, SPO2, and respiratory rate, as an alternative to bedside monitors in hospitals in Ghana.

Gastroscopy, performed as an invasive procedure for the diagnosis and treatment of upper gastrointestinal tract diseases, is often perceived by patients as an unpleasant and frightening experience, leading to anxiety (Hua et al., 2025). The onset of anxiety reduces procedure tolerance and negatively affects patient compliance (Yang et al., 2024). Factors such as pain, fear of complications, loss of control, and inadequate information are frequently cited as contributors to pre-gastroscopy anxiety (Helba, 2024). Anxiety triggers general stress responses-such as tachycardia, hypertension, and respiratory changes-associated with autonomic nervous system activation, and it impacts sedation requirements and cardiopulmonary risks (Liu, 2025). Breathing exercises, a non-pharmacological intervention, are widely recognized in the literature as effective in alleviating anxiety and fostering positive outcomes in patients (Aktaş, 2022; Bulut \& Karabulut, 2023). Breathing exercises stand out as a safe, low-cost method that modulates autonomic nervous system activity (Herawati et al., 2023). This study examines the effects of diaphragmatic breathing exercises performed prior to gastroscopy on anxiety, fear, and vital signs. The results of this study will establish a scientific foundation for healthcare professionals regarding the clinical application of breathing exercises and contribute to evidence-based practices aimed at reducing pre-gastroscopy anxiety and fear while enhancing personal coping.

This prospective observational study aims to evaluate the accuracy, safety, and feasibility of the ANNE® Chest wireless wearable sensor for continuous monitoring of heart rate, respiratory rate, oxygen saturation, and skin temperature in hospitalized neonates, infants, and children (0 days to 12 years of age) in the neonatal and pediatric intensive care units (NICU and PICU). Measurements obtained from the wireless device will be compared with standard-of-care bedside monitoring and capnography. The study will also assess skin tolerability, signal reliability, and caregiver and healthcare provider perceptions of the device.

This prospective observational study aims to evaluate the accuracy, safety, and feasibility of the Wireless MicroPremVitals Button Sensor System for continuous monitoring of electrocardiography (ECG), heart rate, respiratory rate, oxygen saturation, and skin temperature in newborn infants in the delivery room. Measurements obtained from the wireless sensor system will be compared with standard-of-care monitoring. The study will also assess skin tolerability, signal quality, and parent and healthcare provider perceptions of the device.

In this study cameras placed at the bedside will be evaluated for their ability to safely and accurately measure vital signs, such as heart rate and breathing, continuously after heart surgery. Camera-based measurements will be compared with the usual checks that nurses perform several times a day using sensors on the skin or finger clip. The goal is to see whether camera monitoring can help notice changes in a patient's condition earlier. Another aim of the study is to find out whether the camera monitoring can predict if a patient's health is improving or worsening. Patients and healthcare staff will be asked by the investigators about their experience to learn whether this type of monitoring is acceptable in daily care.

This study aims to verify the accuracy of blood pressure, heart rate, blood oxygen saturation, anxiety level, and sleep cycle data measurements obtained from Samsung smartwatches compared to the currently accepted method used in patients with disc herniation undergoing the preoperative period.

This study is an experimental randomized controlled study conducted to compare the effect of two different nonpharmacological treatment methods (aromatherapy and music therapy) on pain, vital signs and parental satisfaction to alleviate or eliminate pain during excretion and filling in children undergoing peritoneal dialysis treatment. The study population consists of pediatric patients aged 3 to 18 years undergoing peritoneal dialysis treatment at Basaksehir Cam and Sakura City Hospital between June 2025- 2026. According to literature, for experimental studies and parametric measurements, at least 30 participants should be included in both experimental and control groups. Therefore, this crossover randomized design will include 45 children per group: control, aromatherapy, and music therapy. Children included in the sample will be assigned to groups based on a crossover randomized design. This method is suitable for studies with a small sample size. Since three different interventions will be applied once per session over three sessions, to avoid bias, the order of interventions will be randomized and labeled as A, B, and C. The researcher will write the names of the interventions on three separate papers, draw them one by one, and assign them accordingly: Method A: Aromatherapy, Method B: Music Therapy, Method C: Control. Then, the six possible sequences (ABC, ACB, BAC, BCA, CAB, CBA) will be written on six papers and drawn randomly to determine the intervention order for each participant.
