what vent setting mode provides the most respiratory support and gives the ability to control RR, PEEP, TV and Fi02 and vent will deliver a set number of breathes each minute if pt does not self-initiate?
what vent setting mode will deliver a set number of breaths if the patient doesn't self-initiate, tidal volume is dependent on whether it is a ventilator breathe or pt breathe, and is a good mode for weaning?
which vent mode setting is used a lot in acute respiratory distress and diseases with decreased lung compliance and it allows the expiratory phase to be longer than normal to keep pressure in the lung higher and Most of the time used in conjunction with high PEEP settings to improve ventilation?
Pressure Release Ventilation (PRV)
which vent setting mode is considered a weaning mode with no set respiratory rate, pt initiates their own breathe and the vent applies pressure to make sure the air gets through the ET tube?
the sickest patient is usually on what vent setting mode?
assist control AC
if your patient is having a gas exchange issue what would you expect their vent setting to be set on?
pressure release ventilation (PRV) it is used in conjunction with a high PEEP
what are the two types of ventilator alarms?
high-pressure alarm and low-pressure alarm
which vent alarm goes off when the pressure increase? for example the patient is coughing or secretions are building up?
high-pressure alarm will go off
how do you trouble shoot the high-pressure alarm?
check tubing for condensation, check tube position, auscultate lung sounds for wheezing, barotrauma (too much oxygen, too fast of breathing), look for secretions in airway
which vent alarm goes off when the pressure decreases? For example there is spontaneous extubation or disconnection of tubing for ET tubing
how would you trouble shoot the low-pressure alarm?
Reconnect the tube to the ventilator, check tube placement, make sure all connections are intact.
