RMIST Intracuff Pressure Monitor
RMIST Intracuff Pressure Monitor – Continuous Cuff Pressure Monitoring During Intubation
The RMIST Intracuff Pressure Monitor, manufactured by Rmist (Tianjin) Medical Device Co., Ltd. in China, is a single-patient-use cuff manometer. It attaches to the pilot balloon of cuffed airway devices such as endotracheal tubes (ETT), laryngeal mask airways (LMA) and double-lumen tubes (DLT), and continuously displays the cuff pressure on its dial during inflation and throughout anesthesia or mechanical ventilation. Prizma Med Sağlık Hizmetleri is the exclusive Türkiye distributor for RMIST.

Why measure cuff pressure?
If cuff pressure is too low, the risk of air leakage and of secretions passing around the cuff (microaspiration) increases; if it is too high, the cuff presses on the tracheal or pharyngeal mucosa and may cause sore throat and hoarseness and, over longer periods, mucosal injury. Estimating cuff pressure by hand (squeezing the pilot balloon) is not reliable, which is why measuring cuff pressure with a manometer is recommended.
How does it work?
The monitor attaches to the pilot balloon and stays connected to the cuff. Coloured zones on the dial show the pressure at a glance:
- Green: Target range (22–32 cmH₂O for the ETT model, 42–60 cmH₂O for the LMA model)
- Yellow: Low pressure; insufficient seal
- Red: Over-inflation
The target pressure is set by the physician according to the patient and institutional protocol.
Key features
- Continuous, real-time cuff pressure indication on a dial with a numerical scale
- No separate manometer or repeated manual checks needed; pressure changes are noticed immediately
- Makes it easier to document cuff pressure
- Single patient use; no cross-contamination between patients
- Latex-free; MRI compatible according to the manufacturer
Scientific background
In a randomized controlled trial by Seet et al. (Anesthesiology 2010;112:652-7, 200 patients), keeping laryngeal mask airway cuff pressure below 44 mmHg (about 60 cmH₂O) with manometry reduced postoperative complaints such as sore throat, hoarseness and difficulty swallowing from 45.6% to 13.4%. This study used manometry measurement, not a continuous monitor.
Areas of use
Patients whose airway is secured with an ETT, LMA or DLT in the operating room, intensive care unit and emergency department.
