| Measure | Time frame |
|---|---|
| Arterial oxygen saturation, which is considered as a hemodynamic parameter. Timepoint: The Arterial oxygen saturation is measured at the beginning of the study (before the intervention) and 1, 5 and 30 minutes after the intervention. Method of measurement: It is controlled and recorded by means of monitoring connected to the patient.;Respiratory rate, which is considered as a hemodynamic parameter. Timepoint: The Respiratory rate is measured at the beginning of the study (before the intervention) and 1, 5 and 30 minutes after the intervention. Method of measurement: For 1 minute, the Respiratory rate is counted and recorded in the patient's chest by observation method.;Arterial blood gases include PH, PCO2, PO2, HCO3, SPO2. Timepoint: Arterial blood gases are measured at the beginning of the study (5 minutes before the intervention) and 25 minutes after the intervention. Method of measurement: Blood gas Technomedica Arterial Blood Gas Analyzer Gastat-720 series.;Heart rate, which is considered as a hemodynamic parameter. Timepoint: The heart rate is measured at the beginning of the study (before the intervention) and 1, 5 and 30 minutes after the intervention. Method of measurement: It is controlled and recorded by means of monitoring connected to the patient.;Blood pressure, which is considered as a hemodynamic parameter. Timepoint: The blood pressure is measured at the beginning of the study (before the intervention) and 1, 5 and 30 minutes after the intervention. Method of measurement: It is controlled and recorded by means of monitoring connected to the patient. | — |
