Overview of RUSH Exam
- Heart: LV function, RV dilation, pericardial effusion/tamponade
- IVC: size and collapsibility (volume responsiveness)
- Lungs: B-lines (pulmonary oedema), pneumothorax (absence of sliding)
- Abdomen: free fluid (haemoperitoneum, ruptured AAA)
- Aorta: AAA
- Lower limbs: DVT (if PE suspected)
- Bedside ultrasound
- Place in subxiphoid/subcostal area and orient head to toe
- Measure the IVC diameter and collapsibility with sharp inspiration (ask the patient to ‘sniff’)
- Estimating CO
- Using LV function on ultrasound as a substitute for CO
- Use the ultrasound in the parasternal long axis view
