Barrel Chest with Tripod Positioning
An increased anterior-posterior chest diameter combined with the patient leaning forward on supported arms to optimize accessory breathing muscle use.
The clinician observes the patient's upper body geometry, looking for signs of chronic muscular compensation during respiration. This fundamental physical examination technique identifies the long-term structural effects of labored breathing. It quickly reveals signs of chronic lung hyperinflation without the need for equipment.
