Question

Regarding mechanical ventilation, what ventilator settings are the primary determinants of oxygenation?

Answer 1

Answer:

The ventilator is not called a magical therapy that provide relaxation to the patient but now it is a simple supportive therapy that help a patient to get up well soon.

Explanation:

Ventilation is used when a patient have hypoxemia and when increased the work before the breathing. The main goal of ventilator is to provide the oxygenation and ventilation to the patients. It reduces the lung injury during ventilation.

Oxygenation is a process that controlled by the positive end expiratory pressure and the fraction in the inspired oxygenation. It also controlled by RR and Vt. There is the fact that help us to understand the mechanical ventilator but later on it limited our understanding the advanced modes of machine.

Answer 2

Answer:

Ventilator are machines to provide mechanical ventilation to a patient, it works by moving air into and out of the lungs  and delivering breaths to the patient if he/she is unable to breathe or having breathing difficulty.

$FiO_2$ and mean airway pressure are two factors that determine oxygenation.  

The average pressure your lung is exposed to during inspiration and expiration during mechanical ventilation is called mean airway pressure.  

$FiO_2$ is the concentration of oxygen in the air that we breathe.
