Inclusion criteria

Inclusion criteria: • American Society of Anesthesiologists physical status (ASA) I-III • Age > 60 year • Patients scheduled for elective surgeries under general anaesthesia.

Exclusion criteria

Exclusion criteria: • Patients with cardiac morbidities (impaired contractility with ejection fraction < 40% and tight valvular lesions, unstable angina). • Patients with heart block and arrhythmia (atrial fibrillation and frequent ventricular or supraventricular premature beat). • Patient with decompansted respiratory disease (poor functional capacity, generalized wheezes, peripheral O2 saturation < 90% on room air). • Patients with increased intraabdominal pressure (intrabdominal mass compressing IVC). • Body mass index =45 kg/m2.

Design outcomes

Primary

Measure	Time frame
The study 1ry outcome will be to rate the Incidence of hypotension after anesthesia Induction. Hypotension can be diagnosed if one of the following conditions is true: (1) a decrease in mean arterial pressure of > 20% compared to the baseline value (2) mean arterial pressure < 60mmHg	—

Secondary

Measure	Time frame
1- Maximum and minimum IVC diameters Maximum and minimum IVC diameters over a single respiratory cycle will be measured using built-in software. 2- Mean arterial blood pressure measured at 1-minute intervals starting from the baseline preoperative reading until skin incision as follows: preinduction reading - 1-minute postinduction reading - 2-minute postinduction reading - preintubation reading - one-minute postintubation reading until skin incision 2- Heart rate measured at 1-minute intervals starting from the baseline preoperative reading until skin incision as follows: preinduction reading - 1-minute postinduction reading - 2-minute postinduction reading - preintubation reading - one-minute postintubation reading until skin incision	—
