Ards Stages

Question 1

Describe phase 1 of ARDS

Answer 1

Injury reduce his normal blood flow to the lungs
Platelets aggregate; release of histamine, serotonin, and bradykinin

Question 2

Describe phase 2 of ARDS

Answer 2

Histamine in flames and damages the alveolar capillary membrane = increase capillary permeability

Histamine breaks down membrane = passages of products that normally should not be there
Then fluid shift interstitial space

Question 3

Describe paste three of ARDS

Answer 3

Cap permeability increases, proteins and fluid leak out = increase interstitial osmotic pressure = pulmonary edema

Fluid now building up in the alveoli

Question 4

Describe phase 4 of ARDS

Answer 4

Decrease blood, flow and fluids and alveoli = damage surfactant = impaired cell ability to produce more

Results in alveoli collapse , impeding gas exchange, and decreasing lung compliance

Question 5

Describe phase 5 of ARDS

Answer 5

Sufficient oxygen cannot cross the membrane, but CO2 can and his loss every exhalation

O2 and CO2 levels decrease in blood = no longer exchanging

Question 6

Phase 6 of ARDS

Answer 6

Worsen, pulmonary edema, inflammation = fibrosis and bad gas exchange
Patient has ARDS now

Lungs are stiff and unable to open /close properly
