This observational study aims to determine the correlation between capillary refill time (CRT) and vital parameters in patients presenting to the emergency department. It explores whether CRT is associated with triage categories and vital signs in non-traumatic patients, including oxygen saturation (SpO₂), heart rate, systolic and diastolic blood pressure, body temperature, forearm temperature, and respiratory rate. Patients admitted to the emergency department of a training and research hospital were assigned triage codes (green, yellow, red). Their CRT was measured three times, and vital signs were recorded accordingly.

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

Triage Code Assignment
Timeframe: Baseline [within 30 minutes of initial Emergency department admission triage assessment]
Capillary Refill Time (CRT) in Seconds
Timeframe: Single measurement by the emergency physician within 10 minutes of the patient's arrival in the emergency care room
Heart Rate
Timeframe: The patient is then assessed by the emergency physician within 10 minutes of being transferred to the ER triage code section. (Single measurement )
Systolic Blood Pressure
Timeframe: Single simultaneous measurement (systolic and diastolic) by the emergency physician within 10 minutes of arrival in the emergency care room (ER).
Diastolic Blood Pressure
Timeframe: Single simultaneous measurement (systolic and diastolic) by the emergency physician within 10 minutes of arrival in the emergency care room (ER).
SpO2 (Oxygen Saturation)
Timeframe: Single measurement by the emergency physician within 10 minutes of the patient's arrival in the emergency care room
Respiratory Rate
Timeframe: Following the patient's admission to the ER, the triage nurse determins the patient's triage code. The patient is then assessed by the emergency physician within 10 minutes of being transferred to the ER triage code section. (single timepoint)
Forearm Temperature
Timeframe: Single measurement by the emergency physician within 10 minutes of the patient's arrival in the emergency care room (ER).
Body Temperature
Timeframe: Single measurement by the emergency physician within 10 minutes of the patient's arrival in the emergency care room (ER).
