Comparison of Arterial and Capillary Blood Gas Analyses in Patients With Respiratory Distress Due to COPD or APE (GAZOCAP)
The assessment of gas exchange is crucial for the management of patients suffering from respiratory distress due to an exacerbation of chronic obstructive pulmonary disease (COPD) or cardiogenic acute pulmonary edema (APE). These measurements are used by physicians to determine the need for noninvasive ventilation (NIV) as well as to evaluate its effectiveness and to decide whether to continue the treatment.
Arterial blood gas analysis is currently the gold standard for the measurement of these gas exchanges, though invasive, painful and risky (failure risks and possible local complications). Capillary blood gas analysis, which consists in collecting a blood drop from the ear or the finger by capillarity after punction, could represent a less invasive alternative. However, data comparing the performances of arterial and capillary blood gas analysis in the context of respiratory distress requiring a NIV remain limited.
This study is based on the hypothesis that capillary blood gas analysis can perform as well as arterial blood gas analysis. It is aimed at comparing values obtained from arterial and capillary blood gas analyses from patients with respiratory distress and requiring a NIV due to an exacerbation of COPD or cardiogenic APE.

Экспериментальный: Respiratory distress arm requiring a noninvasive ventilation
|
The intervention consists in carrying out arterial, veinous and capillary blood gas analyses before submitting the patient to noninvasive ventilation (5 minutes will separate each sampling). Data from these samplings will be recorded. 1 hour after the implementation of the noninvasive ventilation, patients will once again undergo arterial, veinous and capillary samplings for blood gas analyses. Respiratory parameters will be recorded as well at the onset of the noninvasive ventilation and one hour after its start. |
