Spirometry tests were performed using a portable OMI2000 10-L dry-rolling-seal volume spirometer (Occupational Marketing, Inc., Houston, TX) by personnel trained according to the standards of the National Institute for Occupational Safety and Health NIOSHH 1997).
Pulmonary function testing was performed according to National Institute for Occupational Safety and Health (NIOSH) standards (NIOSH 1997) using a portable OMI2000 10-L dry rolling seal volume spirometer (Occupational Marketing, Inc., Houston, TX) before and after 1-hr beach exposure.
21 A 10.2 L, dry rolling seal, volume displacement spirometer (Sensormedics 1022, Occupational Marketing Inc ,Houston, Texas, USA) was used to conduct spirometry while an Ultima PF system (Medical Graphics Corporation, St Paul, Minnesota, USA) was used to conduct DL,CO measurements.
The results of airway sealing pressure, volume of air for cuff inflation to 60 cmH2O, ICP measurement, blood staining and postoperative pharyngolaryngeal morbidity are shown in Table 2.
The Portex Soft Seal high-volume low-pressure (HVLP) cuff has a working intracuff pressure of 30 cmH2O, providing a safe TWP of the same value because there is no tension in the cuff wall material.
The Portex Soft Seal high-volume, low-pressure cuffed tracheal tube was compared with the Mallinckrodt HiLo, Sheridan Preformed and Portex Profile tracheal tubes for leakage of dye placed in the subglottic space of a pig's trachea which was used in a benchtop mechanical ventilation model and in six isolated pig tracheas.
The flat-tube SOFC (FT-SOFC) exhibits the advantages of ease in sealing, low stack volume and low current-collecting resistance.
The advantages of a flat-tube solid oxide fuel cell (FT-SOFC) include easy sealing, low stack volume and low resistance to current collection.
To obtain optimal sealing with high-volume low-pressure cuffs, they should be inflated to obtain a volume above tracheal diameter.
A constant volume sealed chamber is the controlled object.
