CBRT Exercise Part 2 Sinoe the members of the CBRT had good reason to believe that the agent released was phosgene gas, they anticipated an influx of patients with respiratory symptoms to hospitals and dinics over the next several hours. The CBRT opted to inarease the availability of medical staff, especially emergency personnel and respiratory therapists, as well as the number of available mechanical ventilators. The team also issued a mandate that exposed patients presenting with any shortness of breath were to be given supplemental oxygen as soon as possible. Between 2-6 hours after the incident, the witnesses exposed to the gas began arriving at the hospital's emergenoy dyspnea, especially on exertion, a cough, and chest pain. On physical exam and disease: other patients were merely worried that they might experienoe symptoms, but were asymptomatic department. Many patients compliained of some of the patients showed early symptoms of respiratory The CBRT correctly anticipated that after the initial symptom-free lag time, or latent period, many victims attention for respiratory complaints. The preparations the team made were in anticipation of the most dangerous consequenoe of phosgene exposure damage to the respiratory membrane.

O Less air enters the alveoli because the increase in surfaoe tension inareases alveolar pressure and volume. O The ingreased surface tension causes a significant drop in alveolar pressure, which allows too much air to enter the alveoli and they rupture Air does not flow into the alveoli because the increased surface tension prevents an increase in alveolar volume O The inareased surface tension increases the pressure in the alveoli, which causes the volume of the a Submit My Answers Sive Ue

Explanation / Answer

The fourth option is correct.

According to Boyle‘s law, the volume is inversely proportional to pressure.

P V

Here we find that surface tension is increased. If this happens, the pressure will also increase because of Young–Laplace equation. It tells-

p = /R

Here p is the pressure, is the surface tension, and R is radii of the curvature.

Therefore, increased surface tension will also increase the pressure.

If pressure increases, the volume will decreased.

Therefore, the 4th option is correct.
