The implementation protocol of different alternative positions.

Rodin's thinker	The dolphin position	Reverse Trendelenburg position	Alternating prone positioning
Patients sit on a chair and rest their chest on a flat, elevated surface (i.e., their bed or a desk, at an intermammillary line), thus placing the chest in a “semi-prone” position. The head is laid on the arms, elevated and crossed.	Patients reverse their position on the bed, placing their head in the “bed foot area.” In this way, the joint of the bed, normally dedicated to the inclination of the lower limbs, is used to achieve a comfortable chest position.	In a supine position, the patients' hip and knees are not flexed, but the head and chest are elevated at 30° to the abdomen and legs.	1.30 min−2 h: lying on your belly 2. 30 min−2 h: lying on your right side 3. 30 min−2 h: sitting up 4. 30 min−2 h: lying on your left side; then back to position #1 5. repeat the cycles as many times as possible.
