Arterialized ear lobe blood samples have been described as adequate to gauge gas
exchange in acute and chronically ill patients. It is a safe procedure, usually performed by …

BACKGROUND--Techniques for sampling arterialised capillary blood from the finger pulp
and the earlobe were first described over two decades ago but, although close agreement …

Blood gas estimations from arterialized capillary blood versus arterial puncture: are they
different? The answer to this question is that the oxygen tension (PO2) of arterial blood must …

The prescription of long-term oxygen (LTOT) is underpinned by the measurement of arterial
P O2, generally obtained by radial artery puncture. This test is commonly associated with …

Purpose: This study evaluates whether pH, partial pressure of oxygen (PO 2), partial
pressure of carbon dioxide (PCO 2), base excess (BE), and bicarbonate (HCO 3) values of …

Sampling arterialized earlobe blood is thought to be easier and less painful than direct
arterial puncture, and to allow measurement of blood gas values during exercise without the …

Researchers are increasingly looking for reliable non-invasive methods of assessing blood
gas concentrations, and several new techniques have recently become available. Values …

A method is described for the accurate measurement of PO 2 in a drop of blood. The PO 2 of
a drop of blood from the warm earlobe was an accurate representation of arterial PO 2 in 33 …

The purpose of this study was to compare arterial and arterialized blood gases during
normoxic and hypoxic exercise. In the same conditions, earlobe pulse oximetry O2 …

A meta-analysis determined whether capillary blood gases accurately reflect arterial blood
samples. A mixed effects model was used on 29 relevant studies obtained from a …
