SUMMARY
The blood crosses from the right to the left side of the heart without being oxygenated.
1. Anatomic shunts: blood bypasses the alveoli, e.g., intracardiac shunts (ASD, VSD, PDA), pulmonary arteriovenous malformations, fistulas, and hepato-pulmonary syndrome.
2. Physiologic shunting: blood passes through non-ventilated alveoli, for example, pneumonia, atelectasis, and ARDS.
