About

In pediatric cardiac patients with shunt dependent pulmonary circulation, Qp/Qs ratio is a important parameter indicating the balance of pulmonaty and systemic circulation.

This study will calculate Qp/Qs using variables measured using non-invasive monitors (cerebral oximeter and pulse oximeter). This value will be compared with Qp/Qs calculated using variables obtained from blood sample.

Full description

Blood sampling will be performed in both arterial and central venous lines.

Enrollment: 29 patients

Sex: All

Ages: Under 18 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. pediatric cardiac patients scheduled to cardiac operation (shunt dependent pulmonary circulation)
2. preoperative SpO2<97%

Exclusion criteria

1. unable to measure pulse oximeter or cerebral oximeter signal
2. unable to measure SaO2 or SmvO2
3. unstable vital sign

Trial design

29 participants in 1 patient group
