Pulmonary physiology and interpretation of blood gas (PO2, PCO2) results
http://erj.ersjournals.com/content/early/2014/10/16/09031936.00039214.full.pdf+html. Accessed Oct 2014.
Arterial blood gas (ABG) analysis is clinically useful because it allows assessment of two vital interrelated physiological functions: pulmonary gas exchange and maintenance of blood pH (acid-base homeostasis)....

Fetal scalp blood sampling
Sampling capillary blood from the fetal scalp during labor of pregnancy, in order to determine its pH, was introduced to obstetric care in the late 1960s.
Despite current skepticism surrounding its utility, most notably in the US, fetal-scalp blood sampling (FSBS) is still considered a useful fetal monitoring test...

Role of POCT in the management of patients with acute dyspnea
This short review aims to put the diagnostic options provided by state-of-the-art POCT technology into perspective with the clinical challenges faced by physicians treating patients presenting with acute dyspnea.
Natriuretic peptides, hemoglobin, D-dimers and venous blood gases play a key role in the early...

Blood gases and acute pancreatitis
Acute pancreatitis, i.e. acute inflammation of the pancreas, causes sudden onset of severe upper abdominal pain often radiating to the back. Other symptoms include vomiting, constipation and pyrexia. Two main causes - alcohol abuse and gall stone disease – account for the majority (~80 %) of cases. The condition has a ...

Umbilical-cord blood gas analysis
The pH, base excess and pCO2 (acid-base status) of arterial blood flowing through the umbilical cord provides valuable objective evidence of the metabolic condition of neonates at the moment of birth; a notion that has assured a role for the blood gas analyzer in hospital delivery suites in cases of suspected fetal...

The significance of blood gas results following cardiac arrest
Those who have been resuscitated from cardiac arrest may benefit from mechanical-ventilation strategies aimed at maintaining pCO2 above the normal (reference) range, 35-45 mmHg (4.7-6.0 kPa). This is the headline finding of recently published research from the FINNRESCUI study group, a collaboration of Finnish...

Acidosis at birth – significance for very premature, low-birthweight infants
Umbilical-cord blood gas analysis provides objective evidence of the metabolic status of neonates at the time of delivery. Perinatal metabolic acidosis is indicative of hypoxia (sometimes the result of asphyxia during birth) and associated risk of permanent brain damage.
A recently published study sought to assess...

Heparin anticoagulation of samples for blood gas analysis
Since the inception of blood gas analysis, heparin has been the anticoagulant of choice for preparation of samples. Historically, syringes used to collect arterial blood for gas analysis were prepared ”in house” by aspirating a small volume of liquid heparin (LH) and then expelling it. The thin film of liquid heparin...

Postmortem CO-oximetry
CO-oximetry provides the means for automated spectrophotometric measurement of the concentration of total hemoglobin (ctHb) in blood and the percentages of the four hemoglobin derivatives that total hemoglobin comprises: oxyhemoglobin (O2Hb); deoxyhemoglobin (HHb); carboxyhemoglobin (COHb); and methemoglobin (MetHb)....

Laboratory use of umbilical cord blood for critically ill infants
Neonates nearly always experience their single largest day of blood loss on the day of birth due to admission laboratory testing. The term "admission laboratory testing" refers to the initial blood tests done when a baby is born and admitted to the NICU.
Total circulating blood volume in a 3.5 kg term newborn is 280...
