Due to gravity, this medical treatment is more likely to cause injury in non-dependent regions than dependent regions. Infection of patients undergoing this treatment may be prevented through subglottic secretion drainage. The high frequency oscillatory form of this treatment is performed at a frequency exceeding 3 hertz. A type of injury caused by this treatment can be prevented by maintaining a high value of PEEP (“P-E-E-P”), and is caused by repeated cyclic (*) atelectasis (“at-uh-LEK-tuh-sis”). Pseudomonas aeruginosa causes a type of nosocomial pneumonia named for its association with this procedure. A common method of this procedure involves maintaining a positive pressure gradient between the central airways and the alveoli. Severe COVID-19 infection often necessitates, for 10 points, what procedure in which a machine is used to exchange gas for patients unable to breathe? ■END■
ANSWER: ventilation [accept word forms; accept using a ventilator; accept high frequency oscillatory ventilation; accept ventilator-associated pneumonia; accept answers mentioning using a CPAP machine or CPAP therapy; prompt on intubation with “which is a step in what medical treatment?”; prompt on answers referring to placing someone on life support with “what specific treatment are you providing them here?”; prompt on mechanical breathing or respiration but reject answers that use the word “respirator”]
