<p>The thoracoabdominal pressure to occur at the time of crowd accident has the risk to let a person lead to suffocation. This study tested slight pressure on healthy subject's thorax and abdomen. The pressure load up to 40 kg (thorax 20 kg, abdomen 20kg). Pressure loading time defined as up to 20 minutes. We inspected about breathing properties of low tolerance subject for the pressure. As a result, pressure load condition at the interruption of low tolerance group was in condition that load 20 kg on the thorax, and it was suggested that pressure on thorax load was the main factor of the interruption. In addition, vital capacity of low tolerance group by pressure load on thorax of 20 kg is indicated more suppressed than high tolerance group.</p>
