To achieve negative air pressure, external exhausts pull air from the cleanroom at a faster rate than air is introduced over a span of time. The resulting negative pressure means the air will want to flow into the cleanroom to fill the low pressure area, effectively stopping contaminants from...
The air chamber adopts negative pressure seed absorption and positive pressure seed feeding to reduce the seed damage rate to zero, has the advantages of saving seeds, simplifying the process of final singling and thinning, and reducing the production cost, is suitable for directly sowing seeds ...

The effect of NIPPV and NHFOV may be clinically relevant because every additional day of IMV27 and each reintubation28 have been associated with various negative outcomes in similar populations; of note, 2 days of IMV has been associated with significantly increased neutrophil influx into the ...
Air under pressure is introduced into the air channel surrounding the toning channel thus providing a barrier around the toning channel, such that the toner is confined within the channel, thereby preventing unwanted leakage of liquid toner from the channel. 展开 ...
Adverse events such as increased risk of pneumothorax, nasal septal trauma, feeding intolerance, abdominal distension and gram-negative sepsis secondary to nasal mucosal barrier breakdown have been described in the literature with the use of various forms of NCPAP [5, 28, 29]. The incidence of pn...

Therapeutic decisions in patients with sleep apnea (eg, adjustment of continuous positive airway pressure [CPAP]) depend on differentiating central from obstructive apnea. Obstructive apnea is defined by cessation of airflow in the presence of continued respiratory effort, which is conventionally inferred...
