ABSTRACT

Objective: To monitor the levels and clinical value of transcutaneous partial pressure of oxygen (tcpO2) and carbon dioxide (tcpCO2) in patients undergoing balloon pulmonary angioplasty (BPA). Methods: Patients with chronic thromboembolic pulmonary hypertension (CTEPH) treated in our hospital from June 2020 to June 2021 were selected as the research object, and patients with conventional treatment in our hospital were selected as the control. The differences of tcpO2, tcpCO2, oxygen offset and carbon dioxide offset between the two groups were observed. Results: The levels of PaO2 and tcpO2 in CTEPH group were lower than those in control group (P < 0.001), and the levels of PaCO2, tcpCO2, oxygen offset and carbon dioxide offset were greater than those in control group. Conclusion: The levels of PaO2 and tcpO2 in CTEPH patients are low, and the levels of PaCO2, tcpCO2, oxygen offset and carbon dioxide offset are high, which are closely related to the prognosis of CTEPH patients.
