mechanical ventilation

Question 1

what is mechanical ventilation

Answer 1

it uses positive pressures air is pushed into the lung gas flow is stopped and air is allowed to be passively exhaled

Question 2

different types of ventilator modes

Answer 2

-spontaneous breathing-
-controlled ventilation
-mixed ventilation
-supported spontaneous breathing

Question 3

controlled ventilation

Answer 3

these take over the entire breathing effort all breaths are controlled by the ventilator.used when a patient can not breath

Question 4

mixed ventilation

Answer 4

synchronised intermittent mandatory ventilation

if patient does not make effort to breathe the ventilator will be triggered and a breathe will be released- synchronised with patients effort

Question 5

supported spontaneous breathing

Answer 5

preassure support ventilation . The patient triggers the ventilator with their spontaneous effort to breathe.​ventilator responds to the air flow and blows air into the lungs to the pre-set pressure to boost the patient’s inspiratory effort​Therefore​
Completely spontaneous effort​

Question 6

PEEP

Answer 6

positive end expiratory pressure
maintains a positive pressure in the lungs throughout expiration.prevent the lungs from completly emptying. prevents alveolar collapse
