Blood gases in gasometry

P Sławuta, K Glińska-Suchocka
The acid-base balance parameters (ABB) of blood are used in the diagnostics and therapy of acidosis or alkalosis type disorders. Nowadays, some reports on the attempts to use the body cavity fluid for the diagnostics of the ABB disorders have appeared in the human medicine. The study has aimed at comparing the acid-base balance parameters (ABB): pH, pCO2, and HCO3(-) determined in the arterial blood and the fluid from the peritoneal cavity in dogs. The study was carried out on 20 dogs suffering from ascites developed as a result of the chronic renal failure...

Gasometry is the measurement of dissolved gases in the blood, by measuring pH, carbon dioxide pressure (pCO(2)), serum bicarbonate (HCO(3-)), and lactate and serum electrolytes: sodium, potassium and chlorine you can make a diagnosis, etiology and treatment in the critically ill patient. The aim is to provide five steps for the interpretation of blood gases by: 1. The definition of acidemia or acidosis, or alkalemia or alkalosis. 2. Defining the metabolic component or respiratory. 3. To determine the anion gap; levels above 15 ± 2 determine other likely causes of excess anions (methanol, uremia, diabetic ketoacidosis, paraldehyde, ionized, lactic acidosis, ethylene glycol and salicylates...

Arterial gasometry is considered the gold standard for establishing a diagnosis of respiratory failure of any etiology. However, there are some circumstances in which it loses specificity, making necessary to consider other tests such as pulse oximetry to adequately determine hypoxemia. We report a 67 years old patient with sudden hypoacusia, right hemiparesis and polypnea. His laboratory exams on admission, showed extreme hypoxemia in several readings, without correlation to the patient's clinical condition nor the pulse oximetry, and a leukocytosis of 800...

UNLABELLED: Little is known on oxygen saturation in patients with chronic pulmonary embolism. AIM OF THE STUDY WAS: Tto assess the occurrence and importance of oxygen desaturations (D) in these patients. MATERIAL AND METHODS: The study involved 58 normotensive patients with chronic pulmonary embolism (18 males, 40 females, mean age 60 years, range 22-87 years) and was carried out 6 weeks to 2 years after an acute pulmonary embolic event. During 24-hour pulse oximetry mean oxygen saturation (SpO2), and number and duration of desaturations (D), defined as at least a 6% drop of pSO2, below 88%, lasting a minimum of 8 s, were recorded...

Validation must be carried out before a model can be used confidently as a tool of managerial decision making in health care. The authors describe a bootstrap approach to validating models for predicting the utilization of four technologies used in neonatal care: measurement of blood gases (gasometry), the oxygen hood, continuous positive airway pressure (CPAP), and mechanical ventilation. These models were fitted by stepwise multiple linear regression from 20 prognostic covariates of 193 neonates. One hundred bootstrap samples were generated to validate the choices of covariates in the models based on their frequencies of selection...

The final results of arterial blood gases can be affected for several technical factors. If the results have to be corrected for patient temperature, is still a controversial issue. Our observations support that final results should be corrected for temperature because the variation might be clinically relevant in the management of respiratory patients.

During simultaneous evaluation of pulmonary O2, CO2, and CO in the stable state (ES) at rest, CO volume per minute (V'CO) standardized (V'COs) for FICO = 0.001 [2, 3] can be expressed relative to simultaneous flow of "respiratory" gases (V'O2 and V'CO2) by the quotient of the gas concentrations concerned, if its is admitted that V'I = V'E. Whether at the "expired"mean E or "alveolar" A levels, these concentrations have identical paired relationships. In the strict stable state, the proposed expressions of V'CO are constants independent of age, sex, stature, and ventilatory regimen in healthy non-smokers [6]; the result is that V'COs in relation to alveolar ventilation, V'COs/V'A, which is related to V'COs/V'CO2 by PaCO2, is also a constant...

In lasting rest, V'COs (or CO intake standardized for FICO = 0.0001) measures for this gas the activity of the exchange and its yield by DuCO. When V'COs (ml) is expressed for one litre of CO2 reject measured simultaneously, that is for a given metabolic activity, a constant standard is obtained in a healthy non smoking subject independent of its age and of ventilatory or morphometric data. Its lower limit (-2 standard deviations) is 12. V'COs/v'co2 and DuCO express 2 complementary data of the global CO exchange: the specific capacity of CO exchange (relatively to the exchange of the respiratory gas) and its quality...

We performed a functional respiratory examination which consisted of arterial gasometry, spirometry, diffusion capacity to CO2, alveolo-arterial gradient of O2 and pulmonary volumes to 8 patients with cirrhosis diagnosed by clinical history, laboratory exams, abdominal ultrasound and histology. Our results showed a slight obstructive pattern of peripheric airways (FMM: 88.87 +/- 8.7%) in the spirometry, no difference in arterial gases at upright and recumbent position was observed, with low values of apO2 (75...
