Orthopneic or tripod position places the patients in a sitting position or on the side of the bed with an overbed table in front to lean on and several pillows on the table to rest on. Patients who are having difficulty breathing are often placed in this position since it allows maximum expansion of the chest.
Fowler's position is used for people who have difficulty breathing because in this position, gravity pulls the diaphragm downward allowing greater chest and lung expansion.
