Multiple rib fractures can detach a segment of the chest wall, making normal breathing mechanically impossible.
: Rabbits exposed to decompression from 100 kPa to 15 kPa within one minute experienced severe cardiac abnormalities. After an initial increase in heart rate accompanied by struggling, heart rate gradually decreased. P-R and Q-T intervals extended significantly, and animals developed serious atrioventricular block or ventricular arrhythmias. Death ultimately occurred due to complete atrioventricular block accompanied with ventricular standstill. Pathological examination revealed extensive necrosis and disintegration of cardiac muscle cells. lethal pressure crush rabbit
The abdomen lacks the bony protection of the thorax, making it vulnerable to lower pressure thresholds. The liver and spleen—both highly vascular organs—rupture easily under compressive loads. Massive internal hemorrhage follows, leading to hypovolemic shock. Death from abdominal crush typically takes longer than thoracic crush—anywhere from 5 to 30 minutes—as the victim bleeds internally. Multiple rib fractures can detach a segment of
Massive release leads to severe metabolic acidosis, compounding tissue damage and destabilizing vital organ functions. 3. Clinical Manifestations in Rabbits P-R and Q-T intervals extended significantly, and animals
