CO 2 vs. air insufflation in endoscopic ultrasonography: a

The role of CO 2 vs. air insufflation for colonoscopy was also the subject for a meta-analysis by Wu et al. (9 studies, 1577 patients). Despite significant heterogeneity for some major results, data showed that CO 2 insufflation was associated with a significant decrease in abdominal pain during and 1, 6 and 24 hours after the procedure 13.Commissioning of new dissolved air flotation (DAF) installations and optimization of already existing installations takes at least one year of laboratory and pilot plant experiments.

The AirSeal® insufflation device can entrain room air during

The amount of room air as a percentage of the total volume of gas in the surgical cavity at any point in time was calculated as the oxygen percentage multiplied by 4.78, based on the assumptions that (1) room air contains a constant 20.9% of oxygen (100/20.9 = 4.78); (2) room air was the only source of oxygen in the surgical cavity; (3) The second phase is the compression phase, which involves the closing of the larynx and increasing intrathoracic pressure due to abdominal muscle contraction. The final phase of the cough, the expiratory phase, starts with the glottis opening and air flowing at a high rate out of the lungs, intending to remove mucus or other debris.Full article: Mechanical insufflation-exsufflation and available

CO2 insufflation versus air insufflation for endoscopic PubMed

Background: Carbon dioxide (CO2) insufflation is increasingly used for endoscopic submucosal dissection (ESD) owing to the faster absorption of CO2 as compared to that of air. Studies comparing CO2 insufflation and air insufflation have reported conflicting results. Objectives: This meta-analysis is aimed to assess the Flottation naturelle améliorée par l'insufflation au sein de la masse liquide de bulles d'air de quelques millimètres de diamètre.
