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.

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.
