The absence of clear international guidelines complicates recommendations for optimal cuff pressure
range and frequency of intermittent monitoring.
To abolish the influence of cuff pressure
on the MEP, endotracheal cuff pressure
was adjusted between 26 and 30 cm[H.sub.2]O.
To reduce POST, we should use smaller size ET tubes, keeping tracheal cuff pressure
not more than that is required to prevent air leak.
Simultaneously, cuff pressure
(NIBP I) was recorded using appropriate cuff as per AHA JNC 2015 guidelines for BP measurement.
adjustment: in both arms, very high and very low pressures were adjusted as per the recommendation by the ethics committee.
During the manual auscultatory BP measurement, the oscillometric cuff pressure
, as shown in Figure 1, was simultaneously recorded with a sampling rate of 2000 Hz for offline analysing oscillometric waveform and determining automated BPs for each subject.
Compared with conventional electronic BP instruments, the novelty of the proposed BP measurement approach is to utilize a variable volume chamber which actively and stably alters the cuff pressure
during inflating or deflating cycles.

before, during, and after fixed-wing air medical retrieval," Prehospital Emergency Care, vol.
This phenomenon results in an elevated cuff pressure
compared with intra-arterial measurements and is found primarily in advanced age.
Endotracheal tube cuff pressure
measured and regulated in both groups, using a manometer, set on 20 mm Hg (every 6 hours).
After these procedures, the cuff was inflated and the cuff pressure
was adjusted to 20 cm [H.sub.2]O in the Group C.
With all endotracheal tubes, measuring tube cuff pressure
is also an important measure in regard to reduction of VAE.
