Question

1. Briefly describe what it is Peak Inspiratory Pressure and some significantly important in relation to mechanical ventilator management, how it is measured or monitored.

2. Explain and describe the pathophysiological effects or impacts on the lungs, airway, and cardiopulmonary systems.

Answer 1

Peak inspiratory pressure is the prssure needed by the ventilator to deliever a set tidal volume at a given compliance and it is the highest pressure when the lungs during inhalation..The normal peak inspiratory volume need to kept below 20 to 25 cm of H2O.There are certain ciecumstances the peak inspiratory presure may increase like when the patient has increased secetion,bornchosapasm ans so on.

In pressure cyciled ventilator the ventilator pushes air into lungs until a specific airway prssure is reached and in time cycled the ventilator pushes air into lungs until a prset tie has elapsed ,when it comes to volume cycled ventilator it pushes air into lungs until a prset volume is delieverd and constant tidal volume is delieverd regarding of the changing compliance of the lungs and chest wall or the airway resistance in the client or ventilator.An inspiratory positive airway prssure and expiratory postive airway pressure are set on a large ventilator with a desured pressurec support and postive ending expiratory pressure level.This allow more air into and out of the lungs without normal muscular activity needed to do so.For a clent recieving mechanical ventilator always assess vital signs,lung sounds ,respiratory status and breathing patterns.
