Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Pain score in the "Critical Care Pain Observation Tool" questionnaire. Timepoint: Pain score measurement during arterial sampling (when the needle is in the artery), 5 minutes, and 20 minutes after the needle is removed from the artery. Method of measurement: "Critical Care Pain Observation Tool" questionnaire.;Heart rate. Timepoint: Measuring the patients' heart rate in four stages: 5 minutes before the needle enters the artery, during sampling (when the needle is inside the artery), 5 minutes and 20 minutes after the needle leaves the artery. Method of measurement: Measurement with a "monitoring device" and recording in the hemodynamic indicators checklist.;Systolic and diastolic blood pressure levels. Timepoint: Measuring patients' systolic and diastolic blood pressure in four stages: 5 minutes before the needle enters the artery, during sampling (when the needle is inside the artery), 5 minutes and 20 minutes after the needle leaves the artery. Method of measurement: Measurement with a "monitoring device pressure gauge" and recording in the hemodynamic indicators checklist.;Blood oxygen saturation level. Timepoint: Measuring patients' blood oxygen saturation in four stages: 5 minutes before the needle enters the artery, during sampling (when the needle is inside the artery), 5 minutes and 20 minutes after the needle leaves the artery. Method of measurement: Measurement with a "pulse oximeter monitoring device" and recording in the hemodynamic indicators checklist. | — |
