Capnography can serve as a vital monitoring tool to detect critical perfusion abnormalities such as differential lung perfusion in patients with pulmonary artery stenosis.

Variable capnograms may flag differential perfusion in repaired TOF; leaves open whether this refines monitoring or requires prospective validation.
Capnography is a simple non-invasive monitoring technique that provides prompt and valuable information about patient's ventilation, perfusion and metabolism. We are presenting a case of a 10 year-old boy with a history of repaired Tetralogy of Fallot (TOF) undergoing a cardiac catheterization for recurrent left pulmonary artery (LPA) stenosis. A variable plateau capnogram waverform was detected and attributed to ventilation-perfusion abnormalities from differential lung perfusion secondary to critical LPA stenosis. Capnogram can prove vital monitoring tool in detecting critical perfusion abnormalities.

Surendrasingh Chhabada (2020) conducted a case report in Critical Unilateral Pulmonary Artery Stenosis (n=1). Left pulmonary artery balloon angioplasty and stent placement was evaluated on Capnogram waveform normalization.
