Transcutaneous oxygen monitoring. Its use in the treatment of outpatients with congenital heart disease
S. S. Gidding, A. Rosenthal and C. Moorehead
To validate transcutaneous Po2 (TcPo2) monitoring for outpatient use in
cyanotic congenital heart disease (CCHD), TcPo2 was compared with
simultaneous arterial Po2 at cardiac catheterization and with arterial Po2
obtained by puncture. Over a 40-month period, 1,493 outpatient TcPo2
determinations were made in 461 patients to diagnose the presence or
absence of hypoxemia in newly referred patients and to help assess oxygen
delivery in patients with known CCHD. Clinical decisions regarding the need
for further diagnostic study and the adequacy of oxygen delivery were made
based on these determinations.
