A GE LOGIQ S8 ultrasound system with a linear array ultrasound probe having a frequency of 9.0–14.0 MHz was used in this study. All patients underwent lung ultrasound examination immediately after admission (approximately 1.23 ± 0.75 h after delivery based on admission time). The patients were placed in a supine, lateral or prone position in a quiet state, with the anterior and posterior line axillaries as boundaries. The lungs were divided into the front, side and back regions. The examination was performed from the sternal line to the anterior line axillary, from the anterior line axillary to the posterior line axillary, and from the posterior line axillary to the paravertebral line. The scanning was performed sequentially from top to bottom, longitudinally (probe was perpendicular to the rib) and horizontally (probe was along the rib gap), ensuring that the entire scanning area was covered (Figure 1 ). All the ultrasound exams were performed by the same examiner.
Logiq s8 ultrasound system
Manufactured by GE Healthcare
The LOGIQ S8 is an ultrasound system designed for a wide range of clinical applications. It features high-resolution imaging, advanced image processing, and a user-friendly interface. The system is capable of generating detailed images of the body's internal structures to support clinical decision-making.

Abdominal Doppler ultrasound was performed by two experienced sonographers. Patients fasted for 8 hours before ultrasound, and all measurements were conducted with the participants lying supine and breathing normally by using a 3.5-MHz transducer (LOGIQ S7 Expert Ultrasound System, GE Healthcare, Fairfield, CT; LOGIQ S8 Ultrasound System, GE Healthcare, Fairfield, CT; HD 15 Ultrasound System, Philips Healthcare, Reedsville, PA; iU22 Ultrasound System, Philips Healthcare, Reedsville, PA). The gallbladder wall thickness (GBWT) was measured as previously described.[16 (link)] Spleen diameter (SD) was defined as the maximum spleen bipolar diameter.[17 (link)] Portal vein diameter (PV) was defined as the maximum diameter of PV in hepatic hilum.[18 (link)] All measurements were performed in triplicate, and then averaged, expressing the results in millimeters (mm).

The GFR was determined in conscious unrestrained mice and rats using the excretion kinetics of an i.v. bolus of fluorescein isothiocyanate C-sinistrin (mice: 6 mg/100 g BW; rats: 8 mg/100 g BW; Fresenius Kabi AG, Bad Homburg, Germany) using a miniaturized fluorometric detector (NIC-Kidney excitation, 480 nm/emission, 521 nm; Mannheim Pharma & Diagnostics, Mannheim, Germany). The GFR was calculated using the half-life derived from the rate constant of the single exponential phase of the fluorescein isothiocyanatesinistrin excretion curve, as described. 55 Kidney sonograms and vascular resistance measurements Kidney sonograms were performed using a General Electric Logiq S8 Ultrasound System with L8-18i transducer (GE Healthcare, Chicago, IL). Doppler images were obtained through a dorsal window that allowed a kidney projection in a longitudinal view. The color Doppler sample volume was opened to include the whole kidney. Renal images plus measurements of the renal artery systolic and diastolic velocity were obtained. The renal artery resistive index (RI) was calculated using the formula: RI ¼ (peak systolic velocityenddiastolic velocity)/peak systolic velocity.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
