Sublingual Tonometry to Assess Tissue Perfusion in Patients With Chronic Obstructive Pulmonary Disease (COPD)

NCT01169506 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 66

Summary

Sublingual positioning of a silicon capillary system is applied. After 15 min, while the individual is in resting position with closed mouth and normal tidal breathing through the nose is performed, the silicon capillary system is connected to a capnometer and CO2 tension is measured.

The investigators hypothesis is that this setup offers a non-invasive assessment of ventilatory efficiency with similar accuracy as arterial PCO2.

Interventions

DEVICE

sublingual silicon capillary

Stable patients with COPD and healthy individuals were asked to open their mouth and a small butterfly silicon capillary was placed sublingually. After 15 minutes, while the mouth was closed completely and nose breathing was performed, the capillary system was connected to a capnometer and sublingual tonometric PCO2 was measured. At the same time, PETCO2 was also measured and arterial blood was drawn for pH, PO2 and PCO2 analysis
