Study Arms:
- Sitting Position (head of bed 90 degrees) (Type: None): Ultrasound measurements will be performed. A= skin to the pleura at the level lateral to the subclavian artery, B= skin to center of the subclavian artery, C= skin to first rib, D= skin to corner pocket
- Semi-sitting position (45 degrees) (Type: None): Ultrasound measurements will be performed. A= skin to the pleura at the level lateral to the subclavian artery, B= skin to center of the subclavian artery, C= skin to first rib, D= skin to corner pocket
- Supine position (Type: None): Ultrasound measurements will be performed. A= skin to the pleura at the level lateral to the subclavian artery, B= skin to center of the subclavian artery, C= skin to first rib, D= skin to corner pocket
