Objective: There is an increasing body of literature supporting universal umbilical cord blood gas analysis (UCBGA) into all maternity units. A significant impediment to UCBGA’s introduction is the perceived expense of the introduction and associated ongoing costs.
Simple diagnostic tools, such as arterial blood gas (ABG) analysis, are often used at the bedside by clinicians to assist in making difficult management decisions in patients with suspected PE (e.g., to pursue a diagnosis of PE or not, to presumptively anticoagulate or not).
Confirm an increase in of more than 0.5 kPa using blood gas analysis After completion of the apnoea test, the ventilator should be reconnected. Acid–base status should be …
Measurement of arterial blood gases (ABGs) involves a sample of blood being taken from an artery (most commonly from the pulsation at the wrist). The ABG is then analysed on a special machine. The ABG is then analysed on a special machine.
Arterial blood gas analysis is a useful tool for diagnosis monitoring and as an aid in management, but its value is limited by the understanding of the basic physiology and ability of the surgeon to interpret the report. Using a systematic and logical approach by using these steps would make the interpretation simple and easy to use.
Cyanosis affects co-oximetry (i.e., blood gas analysis in the laboratory) differently than it affects pulse oximetry (i.e., equipment used at the bedside; see Chapter 20). Because co-oximetry can distinguish deoxyhemoglobin from other abnormal hemoglobin, it indicates hypoxemia only in patients with central cyanosis (i.e., it samples arterial blood and therefore indicates normal oxygen levels
The frequency of arterial blood gas analysis should be dictated by the acuity of illness, availability of noninvasive monitoring, and frequency of ventilator changes. f.
Normal values for blood gas analysis are given in Table 8–1, and capillary blood gases are discussed in a following section. Mixed venous blood gases are reviewed in Chapter 20 . The bicarbonate concentration ([HCO 3 – ]) from the blood gas is a calculated value and should not be used in interpretation of blood gases; the [HCO 3 – ] from a concurrent chemistry panel should be used.
Bedside diagnosis of alcohol intoxication with a pocket-size breath-alcohol device: sampling from unconscious subjects and specificity for ethanol.

Noninvasive bedside techniques that aid in the diagnosis and evaluation of PE are based on respiratory parameters derived from the alveolar dead space. Using volumetric capnography (VCap), Eriksson and colleagues 3 described a graphic method of extrapolating the arterial to end-tidal CO 2 gradient [P(a-et)CO 2 ] to a prolonged expiration.
The arterial blood gas (ABG) analysis is the tool for diagnosis of the acid/base state. The test includes: pH – measures the amount of H+ concentration. PaCO2 – partial pressure of arterial CO2 HCO3- reflects the activity of the kidneys in retaining or excreting bicarbonate. PO2-partial pressure of O2 Base excess – Lewis says +/- 2mEq/L – other sources said +/- 3.0 mEq/L Ventilation – The

Although several measures, such as the ratio of PaO2 to FIO2 and the Lung Injury Score (LIS), have traditionally been used in both clinical practice and clinical trials, these offer limited prognostic information or require arterial blood gas analysis,6-11 highlighting
Abdominal symptoms are often hidden by the presence of deep sedation and/or analgesia, so laboratory tests (e.g. leucocytes count, procalcitonin, lactate or specific enzymes plasma levels), arterial blood gas analysis and, above all, radiological findings, become the key to a correct diagnosis of intraabdominal pathology. However, radiological examinations are not always possible or accurate
