10.1007/s001010050146. How do you measure cuff pressure? Cuff pressures less than 20cmH2O have been shown to predispose to aspiration which is still a major cause of morbidity, mortality, length of stay, and cost of hospital care as revealed by the NAP4 UK study. Curiel Garcia JA, Guerrero-Romero F, Rodriguez-Moran M: [Cuff pressure in endotracheal intubation: should it be routinely measured?]. chin anteriorly), no lateral deviation, Open mouth and inspect: remove any dentures/debris, suction any secretions, Holding laryngoscope in left hand, insert it looking down its length, Slide down right side of mouth until the tonsils are seen, Now move it to the left to push the tongue centrally until the uvula is seen, Advance over the base of the tongue until the epiglottis is seen, Apply traction to the long axis of the laryngoscope handle (this lifts the epiglottis so that the V-shaped glottis can be seen), Insert the tube in the groove of the laryngoscope so that the cuff passes the vocal cords, Remove laryngoscope and inflate the cuff of the tube with 15ml air from a 20ml syringe, Attach ventilation bag/machine and ventilate (~10 breaths/min) with high concentration oxygen and observe chest expansion and auscultate to confirm correct positioning, Consider applying CO2 detector or end-tidal CO2 monitor to confirm placement, if it takes more than 30 seconds, remove all equipment and ventilate patient with a bag and mask until ready to retry intubation. For example, Braz et al. 32. They were only informed about the second purpose of the study: determining the relationship between cuff volume and pressure. 2, pp. Morphometric and demographic characteristics of the patients were similar at each participating hospital (Table 1). . 10911095, 1999.

The loss of resistance syringe method was superior to pilot balloon palpation at administering pressures in the recommended range. The patient was then preoxygenated with 100% oxygen and general anesthesia induced with a combination of drugs selected by the anesthesia care provider.

With IRB approval, we studied 93 patients under general anesthesia with an ET tube in place in one teaching and two private hospitals. In the later years, however, they can administer anesthesia either independently or under remote supervision. However, the presence of contradictory findings (tense cuff bulb, holding appropriate inflating pressure in the presence of a major air leak) confounded the diagnostic process, while a preoperative check of the ETT would have unequivocally detected the defect in the cuff tube.

[21] observed that when the cuff was inflated randomly to 10, 20, or 30 cmH2O, participating physicians and ICU nurses were able to identify the group in 69% of the high-pressure cases, 58% of the normal pressure cases, and 73% of the low pressure cases.
