Transcutaneous carbon dioxide for short-term monitoring of neonates.
We studied transcutaneous pCO2 monitoring in 70 neonates, most of them premature with respiratory distress syndrome. Measurements were at 44 degrees C. Calibration drift was large in some instances. Least squares linear regression analyses of transcutaneous pCO2 (y) vs arterial pCO2 (x) in kilopascals showed, for all observations (n = 516), for one observation randomly selected from each patien...
متن کاملInfluence of total face, facial and nasal masks on short-term adverse effects during noninvasive ventilation.
OBJECTIVE Failure of noninvasive ventilation (NIV) has been associated with short-term adverse effects related to the use of masks. The aim of this study was to compare the incidence, type and intensity of adverse effects, as well as the comfort, of total face masks (TFMs), facial masks (FMs) and nasal masks (NMs) during NIV. METHODS This was a randomized crossover trial involving 24 healthy ...
متن کاملEstimating Soil Carbon, Nitrogen, and Phosphorus Mineralization from Short-Term Carbon Dioxide Respiration
The measurement of soil carbon dioxide (CO2) respiration is a means to gauge biological soil fertility. Test methods for respiration employed in the laboratory vary somewhat, and to date the equipment and labor required have limited more widespread adoption of such methodologies. A new method to measure soil respiration was tested along with the traditional alkali trap and titration method. The...
متن کاملCarbon dioxide rebreathing in respiratory protective devices: influence of speech and work rate in full-face masks.
UNLABELLED Carbon dioxide (CO2) rebreathing has been recognised as a concern regarding respirator use and is related to symptoms of discomfort, fatigue, dizziness, headache, muscular weakness and drowsiness. Previous investigations are limited by small sample size and have not evaluated the relationship between CO2 inhalation and phonic respiration (breathing during speech) in respiratory prote...
متن کاملReview: thrombolysis increases short-term death and intracranial hemorrhage but decreases long-term death or dependence.
D a t a e x t r a c t i o n Data were extracted on patients, drug dose, administration route, duration of treatment, stroke type, results of computed tomography, and duration of follow-up. Outcomes were all-cause mortality 7 to 10 days after treatment, symptomatic or fatal intracranial hemorrhage, all-cause mortality at long-term follow-up, and poor functional outcome. Study quality was assesse...
