Endotracheal temperature and humidity measurements in laryngectomized patients: intra- and inter-patient variability |
Abstract | ||
|---|---|---|
This study assesses intra- and inter-patient variability in endotracheal climate (temperature and humidity) and effects of
heat and moister exchangers (HME) in 16 laryngectomized individuals, measured repeatedly (N = 47). Inhalation Breath Length (IBL) was 1.35 s without HME and 1.05 s with HME (P 2O/L (P P < 0.0001). For the temperature and humidity minimums, the inter-patient variability was much smaller than the short- and
long-term intra-patient variability. For exhalation breath length and full breath length, the opposite was the case. Conclusions:
(1) Because inter-patient variability is smaller than intra-patient variability, investigating endotracheal climate in a limited
number of laryngectomized subjects is justified, provided repeated measurements per patient are accomplished; (2) main contributor
to intra-patient variability is the positioning of the catheter tip in the trachea; (3) an HME leads to a shortened IBL which
enhances the HME effect. |
