The equation was applied to measurements of PETCO2 obtained in two previous studies in 10 subjects in which PaCO2 had been measured, and was found to predict PaCO2 to within 1.04 Torr (+/- SD) for PaCO2 between 25 and 58 Torr (n = 56; r = 0.962). The effect of the response ...
After institutional approval had been obtained, between four and seven sets of arterial and mixed venous blood gas measurements and cardiac output estimations were obtained from each patient. The following measurements were recorded: PaO2, PaCO2, arterial haemoglobin saturation (SaO2), mixed venous ...
Analysis of end-tidal and arterial PCO2 gradients using a breathing model The aim of this paper was to analyse the difference between end-tidal carbon dioxide tension (PETCO2) and arterial carbon dioxide tension (PaCO2) at rest a... H Benallal,T Busso - 《European Journal of Applied Physiol...
The purpose of this study was to evaluate the stability of the arterial PCO2 (PaCO2) to end-tidal PCO2 (PetCO2) partial pressure difference (Pa-etCO2) during surgery usingPetCO2 monitoring, in children with congenital heart disease (CHD). Forty children with CHD were studied: ten children ...
Advance the blade until it reaches the angle between the base of the tongue and epiglottis.( volecular space) Lift the laryngoscope upwards and away from the nose – towards the chest. This should bring the vocal cords into view. It may be necessary for a colleague to press on the trach...
The difference between mixed venous blood carbon dioxide tension (PvCO2) and arterial carbon dioxide tension (PaCO2), called PCO2has been proposed to better characterize the hemodynamic status. It depends on the global carbon dioxide (CO2) production, on cardiac output and on the complex relation ...
In turn, the decrease in PaCO2 was probably associated with hyperventilation that maintained the PaO2 at a constant level during repeated sprints. Results show that SID, [Atot] and PCO2 have different effects on plasma [H+] and [HCO3] at sites A and V and that the chloride shift is ...
The LOS of cases varied between 1 and 28 days, with an average of 7.00 卤 3.83, ICU admission rate was 8% and the overall mortality rate was 5.4%. Albumin (AUC 0.81) and pH (AUC 0.68) showed the highest 30-day mortality prediction. While A-a O2 gradient difference (AUC 0.68) ...
