When do you use cuffed endotracheal tube?

Advantages of using cuffed ETTs. Cuffed ETTs potentially offer the advantages of: lower rate of ETT leak; improved ventilation; less reintubations to find the correct ETT size; a smaller ETT through the delicate cricoid; less ventilator-associated pneumonia/aspirations; and the use of less anaesthetic and other gases.

Why is it important to measure cuff pressures?

The importance of tracheal tube cuff pressures is highlighted by the spectrum of complications that can occur: high cuff pressures can result in complications ranging from sore throat and hoarseness to tracheal stenosis, necrosis, and even rupture, while cuff pressures that are too low place the patient at risk for …

Why are some Trach cuffed?

Tracheostomy tubes can be cuffed or uncuffed. Uncuffed tubes allow airway clearance but provide no protection from aspiration. Cuffed tracheostomy tubes allow secretion clearance and offer some protection from aspiration, and positive-pressure ventilation can be more effectively applied when the cuff is inflated.

How is ET tube size measured?

The average size of the tube for an adult male is 8.0, and an adult female is 7.0, though this is somewhat an institution dependent practice. Pediatric tubes are sized using the equation: size = ((age/4) +4) for uncuffed ETTs, with cuffed tubes being one-half size smaller.

How often should cuff pressure of ET tube be monitored?

A cuff pressure between 20 and 30 cm H2O is recommended to provide an adequate seal and reduce the risk of complications. Survey results5–7 indicate that cuff pressure is usually monitored and adjusted every 8 to 12 hours.

What is the purpose of cuff?

The functional reason for the cuffs is to add weight to the bottom of the leg, to help the drape of the trousers. Parents may also use cuffs to extend the life of children’s clothes by buying pants that are too long, cuffing the leg and then unrolling it as the child grows.

How many types of ET tube are there?

Types of endotracheal tubes include oral or nasal, cuffed or uncuffed, preformed (e.g. RAE (Ring, Adair, and Elwyn) tube), reinforced tubes, and double-lumen endobronchial tubes.

When should ET tube be removed?

The endotracheal tube should be removed as soon as the patient no longer requires an artificial airway. Patients should demonstrate some evidence for the reversal of the underlying cause of respiratory fail- ure and should be capable of maintaining adequate spontaneous ventilation and gas exchange.

What are cuffed endotracheal tubes used for?

cuffed endotracheal tube. an endotracheal tube with a balloon at one end that may be inflated to tighten the fit in the lumen of the airway. The balloon forms a cuff that prevents gastric contents from passing into the lungs and gas from leaking back from the lungs. Both high-pressure and low-pressure cuffs are used.

Are there any disadvantages to using a cuffed tube?

On the other hand, there are potential disadvantages to using cuffed tubes in small children. cuffs take up space and force use of a smaller tube. decreasing the tube radius a little greatly increases resistance and significantly decreases flow.

Why was endotracheal intubation done with rubber tubes?

In 1946 an alarmed Dr J.U. Human wrote to complain that the ordinary rubber ETTs were too hard, and caused bleeding when used nasally, a complication which he felt might “bring the practice of endotracheal intubation into disrepute”. He had to actually soften his rubber tubes in kerosene before he was able to use them safely.

Can a pediatric endotracheal tube be uncuffed?

In the pediatric population the cricoid ring is sufficiently narrow to form a seal all by itself, and thus the tubes can be uncuffed for this population.
