Medline AG Cuffill cuff pressure manometer HCSCUFF0041 in a gloved hand, digital display reading 26 cmH2O, graduated 10 cc barrel and luer tip - Pacific Biomedical

AG CUFFILL, ETT Cuff Pressure Manometer

SKU: MED-HCSCUFF0041

Medline Industries

The AG Cuffill is a pocket-sized digital cuff pressure manometer made by Medline Industries, sold under item number HCSCUFF0041. It measures and adjusts the pressure in the air-filled cuff of an endotracheal tube, tracheostomy tube or laryngeal mask airway. The display reads 0 to 99 cmH2O to within 2 cmH2O, and the 0 to 10 cc plunger adds or removes air, so you measure and set the cuff with one device. The luer tip connects straight to the pilot balloon. Sold as 1 each: one device, non-sterile, battery built in, ready to use. Labeled for single-patient use with a 100-reading counter; between patients, clean it with a listed disinfectant wipe and keep using it within that limit.

Product Highlights

  • Measures and adjusts in one device: read the cuff, then push or pull the plunger to set it, with no separate syringe or dial gauge.
  • Digital readout in cmH2O, the unit your protocol uses, accurate to ±2 cmH2O across 0 to 99 cmH2O.
  • 100-reading service life with the remaining count shown at every power-on, so you know when a device is near the end.
  • Fits every cuffed airway with a luer pilot balloon: endotracheal tubes, tracheostomy tubes and laryngeal mask airways.
  • At 18 g it rides in a jump bag, flight suit pocket or airway kit and stays at the bedside.
  • Shows 00 at power-on and re-zeroes with a 5-second button hold if it ever shows anything else; no routine calibration required.
  • Wipes clean between patients with Super Sani-Cloth, Sani-Cloth Prime, Medline Micro-Kill One and other listed disinfectant wipes, and shuts off automatically 60 seconds after activation.

Why cuff pressure is measured, not estimated

Cuffs inflated by feel are usually wrong. With conventional inflation, 69% of 100 adult patients had cuff pressures above the 20 to 30 cmH2O range.1 Among 55 patients intubated before helicopter transport, the mean cuff pressure was 70 cmH2O and 84% were above 30 cmH2O.2 In one anesthesia quality program, over-inflation occurred in 59% of cases at baseline; after manometers and training that fell to 27%, and postoperative sore throat dropped from 60% to 32%.3

Pressure also drifts between checks. Under usual care, 51.7% of cuff pressure readings fell outside 20 to 30 cmH2O, against 11.1% with an active monitoring intervention, and pressure decreased over time without it.4 In ventilated ICU patients, only 41.5% of 2,120 measurements taken 2 to 4 hours after the routine check were in range, and 53% were below it.5 In flight, cuffs set to a mean 25.1 cmH2O at takeoff rose a mean 10.8 cmH2O at cruise altitudes of 1,000 to 3,000 ft.6 Pressure drifts within hours of a check and rises in flight, so check at your protocol's routine interval and again after suctioning, repositioning, coughing, transport or a change in altitude.

The 20 to 30 cmH2O target balances seal against perfusion. Tracheal mucosal blood flow falls as cuff pressure rises, which is why 30 cmH2O (22 mmHg) is the accepted ceiling,7 and the range is recommended to reduce tracheal injury and ventilator-associated pneumonia risk.8 Routine manometry reduced moderate-to-severe postoperative sore throat, hoarseness and dysphagia across 558 surgical patients.9 Laryngeal mask cuffs are different: the LMA Unique, for example, is inflated to a maximum of 60 cmH2O.10

The AG Cuffill tracks a standard cuff manometer closely: in 200 pediatric patients, R2 0.9943 with a bias of -0.53 ± 0.68 cmH2O.11 On a ventilated patient the display cycles with each breath, and the correct cuff pressure is the lowest value in the cycle; with the plunger fully in, the device has minimal dead space, so connecting it does not bleed pressure from the cuff.12 Disconnect after each reading (the device is not for continuous monitoring), expect a drop of 1 to 2 cmH2O when you disconnect, and use it only on air-filled cuffs. Full operating, cleaning and storage instructions are in the Instructions for Use.13

Who Uses This

Ground EMS and Ambulance

Cuffs inflated by feel in the field run high; a reading after intubation and again before handoff puts the cuff in range before the receiving team ever sees it.

Air Medical and HEMS

Cuff pressure rises with altitude; a check at takeoff and again at cruise keeps the cuff at 20 to 30 cmH2O through the flight.

Hospital ED, ICU and Respiratory Therapy

Pressure drifts within hours of a check; a bedside manometer makes scheduled and post-suction checks routine on endotracheal and tracheostomy tubes.

Anesthesia and OR

Routine manometry reduces postoperative sore throat, hoarseness and dysphagia; one device sets the endotracheal cuff after intubation and verifies LMA cuff pressure.

Frequently Asked Questions

How does the AG Cuffill work?
Power it on, push the plunger fully in, connect the luer tip to the pilot balloon and read the cuff pressure in cmH2O on the display. To adjust, move the plunger (in to add air and raise the pressure, out to draw air and lower it), then disconnect after the reading; the device shuts off on its own after 60 seconds.
How accurate is the Cuffill?
Accuracy is ±2 cmH2O across the 0 to 99 cmH2O range; the display shows 00 at power-on and can be re-zeroed by holding the power button for 5 seconds while disconnected. In 200 pediatric patients it tracked a standard cuff manometer with a bias of -0.53 cmH2O, and with the plunger fully in it has minimal dead space, so connecting it does not bleed pressure from the cuff.
Is the Cuffill single-use or reusable?
Both, within limits: it is labeled for single-patient use and carries a 100-reading counter, and after a wipe-down with a listed disinfectant it can be used on the same or a different patient until that count runs out. When the limit is reached the display shows E1 and the device is discarded per facility policy.
What is the normal endotracheal tube cuff pressure?
Keep an endotracheal or tracheostomy tube cuff at 20 to 30 cmH2O (about 15 to 22 mmHg): high enough to seal the airway, low enough to preserve tracheal mucosal blood flow. Laryngeal mask cuffs use a different limit; the LMA Unique, for example, is inflated to no more than 60 cmH2O, so check the airway's own labeling.
How often should cuff pressure be checked?
There is no single fixed interval, so check at your protocol's routine interval and again after anything that can change the cuff: suctioning, repositioning, coughing, transport or a change in altitude. Pressure drifts within hours of a check and rises in flight, so a reading before and after transport is good practice.
Why does the reading fluctuate on a ventilated patient?
The cuff sits in the airway, so each ventilator breath briefly raises the pressure around it and the display cycles up and down with the respiratory cycle. Read the lowest value in the cycle as the cuff pressure and set your 20 to 30 cmH2O target against that number, not the peak.
What do 1H and E1 on the display mean?
At power-on the display blinks the number of readings left and then shows 00; 1H means more than 100 readings remain on a new device. E1 means the 100-reading limit has been reached and the device will not take another reading, while E2, E3 or E4 indicate a system error and the device is not usable.
How should the Cuffill device be cleaned?
Wipe the device after each patient with a listed disinfectant wipe such as Super Sani-Cloth, Sani-Cloth Prime or Medline Micro-Kill One, or scrub with Alconox 1% or chlorhexidine 4% followed by 70% isopropyl alcohol or 1.4% hydrogen peroxide. Pull the plunger out to clean it, keep fluid away from the black sensor gasket and keep the device dry.
