Answer to Question 1

I appreciate you answering this question. This is a great community

Answer to Question 2

ANS: D
Patients who have nasotracheal tubes usually have tubes that are smaller than they would be if they were intubated orally. This increases the resistance through the artificial airway, making pressure support necessary when the patient is breathing spontaneously. Patients with small spontaneous tidal volumes can be assisted with pressure support to increase their tidal volumes. The pressure-support ventilation level can be adjusted to attain the desired tidal volume based on the patient's ideal body weight. Patients with high respiratory rates can also benefit from pres-sure-support ventilation. Titrating the pressure support level to the patient's respiratory rate and tidal volume provides the appropriate assistance to overcome the airway and artificial tubing re-sistance and improve the patient's work of breathing.

Did you know?

As many as 28% of hospitalized patients requiring mechanical ventilators to help them breathe (for more than 48 hours) will develop ventilator-associated pneumonia. Current therapy involves intravenous antibiotics, but new antibiotics that can be inhaled (and more directly treat the infection) are being developed.

Did you know?

The use of salicylates dates back 2,500 years to Hippocrates’s recommendation of willow bark (from which a salicylate is derived) as an aid to the pains of childbirth. However, overdosage of salicylates can harm body fluids, electrolytes, the CNS, the GI tract, the ears, the lungs, the blood, the liver, and the kidneys and cause coma or death.

Did you know?

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.
