What is a ProSeal LMA?
The LMA ProSeal™ is a reusable supraglottic airway device that incorporates a gastric drainage tube placed lateral to the main airway tube and which ends at the tip of the mask [12].

What is seal pressure in LMA?
The LMA forms a low pressure seal around the larynx, with a mean leak pressure of 20 cm H,O in pediatric pa- tients.
How many types of LMA are there?
Laryngeal mask airways come in several types, as follows: The LMA Classic is the original reusable design. The LMA Unique is a disposable version, making it ideal for emergency and prehospital settings. The LMA Fastrach, an intubating LMA (ILMA), is designed to serve as a conduit for intubation.
What is an LMA used for?
Laryngeal mask airways (LMA) are supraglottic airway devices. They may be used as a temporary method to maintain an open airway during the administration of anesthesia or as an immediate life-saving measure in a patient with a difficult or failed airway.
What is leak pressure?
Oropharyngeal leak pressure (OLP), measured by closing the expiratory valve of the anesthetic circle system at a fixed gas flow rate and noting the equilibrium airway pressure, is used to quantify the efficacy of airway sealing in SGA devices.
How do you check for leak pressure in LMA?
Measurements and main results: The LMA leak pressure was determined by closing the circuit popoff valve and recording the pressure at which gas was first heard to escape around the LMA at the mouth. The LMA cuff pressure was determined by connecting the check valve of the LMA pilot balloon to a sphygmomanometer.
What are the sizes of LMA?
Answer
| Weight, kg | Mask Size | LMA Models |
|---|---|---|
| 20-30 | 2.5 | Classic, Unique |
| 30-50 | 3 | Classic, Unique, Fastrach |
| 50-70 | 4 | Classic, Unique, Fastrach |
| 70-100 | 5 | Classic, Unique, Fastrach |
How much air is in a LMA?
In summary, the minimum effective cuff volume for LMA Well Lead™ is 7–9 ml, which is responsible for the reduction in the incidence of postoperative pharyngeal complications for those patients using LMA.
Can a nurse insert an LMA?
The LMA has been successfully used by nurses during cardiopulmonary resuscitation (Baskett, 1994). Ventilation using a bag/valve/LMA device is more efficient, and certainly easier, than the conventional bag/valve/mask device, and the incidence of regurgitation is lower (Resuscitation Council (UK), 2000).
How is an LMA inserted?
The LMA is a tube with an inflatable cuff that is inserted into the oropharynx. A: The deflated cuff is inserted into the mouth. B: With the index finger, the cuff is guided into place above the larynx. C: Once in place, the cuff is inflated.
Is the Igel an LMA?
The i-gel is a disposable supraglottic airway device with a noninflatable cuff, and the laryngeal mask airway (LMA) Classic is a reusable device with an inflatable cuff.
How do you find a leak in a LMA?
Which fluid is used in leak test?
The test consists of bombing the package with a fluorocarbon liquid (detector liquid) that has a boiling temperature from 50°C to 95°C for a length of time and pressure.
How do I confirm my LMA placement?
After insertion, placement of the LMA was confirmed by clinical tests, ultrasound examination and fiberoptic laryngoscopy. Of the 64 women, placement was confirmed as acceptable in 89.1% by clinical tests, in 59.4% by fiberoptic laryngoscope assessment and in 67.2% by ultrasound examination.
How do I choose the right size LMA?
In addition, there is little difference between the calculated LMA size–patient weight relation between this formula and the recommended formula. 1For example, if the patient weighs 15 kg, the calculation would be as follows: LMA size ≥ (15/5)0.5= (3)0.5= 1.7. In this case, a No. 2 LMA would be used.
How do I know what size LMA to get?
The following are practical guidelines when choosing an LMA size: Generally, the size 4 LMA will be suitable for most adult female patients, and the size 5 LMA for adult males up to 100 kg. The new size 6 is intended for adult patients over 100 kg. The size 6 device is intended for adult patients over 100 kg.
