Pharmacology
This group of medications stop muscle movement?
Paralytics
High levels of PEEP can cause a dilating of the capillaries and increase pulmonary vascular resistance.
True or false
false
During mechanical ventilation damage to the lungs caused by high pressures is called volutrauma.
True or false
false
You are weaning a chronic CO2 retainer from the mechanical ventilator, the least appropriate goal would be?
Normalize CO2
You are deciding to wean or not, the patients shunt is 15mmHG. Do you wean?
yes
This is the drug of choice to treat delirium.
Haldol
A fall in blood pressure caused by mechanical ventilation can stimulate the kidneys to a increased release in which hormone?
ADH
80/20 Heli-OX mixture lowers peak inspiratory pressure because it?
Is not as dense so flow is not as turbulent.
Your giving an IPPB treatment but the patient's tidal volume is high, the most appropriate action would be?
Decrease pressure limit
To consider weaning the A-aDo2 should be
<300mm Hg
What group of drugs are used to reduce anxiety.
Sedatives
If ADH is released it will cause?
Low urine output
A side affect of mechanical ventilation that requires high ventilating pressure.
pneumothorax
PIP=28, Plateau=21, ABG's: pH=7.32, PaCO2=52, HCO3=23, PaO2=81. The most appropriate ventilator change to increase ventilation would be to?
increase Vt
If your patient in pressure support ventilation, developed a large mucus plug, you would expect to see?
High peak pressures, low tidal volumes
Which group of medications will not help with pain?
Paralytics
The fall in intrapleural pressure that draws air into the lungs during inspiration also draws blood into the major thoracic vessels and heart.
True or false
True
When the alveoli become overdistended the ______________ decreases?
compliance
The high pressure alarm is sounding on the ventilator, which of the following are most likely cause? Multiple
Leak in circuit
Kink in circuit
Occlusion
Right mainsteam intubation
interpret these abgs: pH=7.12, PaCO2=60, HCO3=24
respiratory acidosis
A ramsay score of 2 to 4 indicates?
Adequate sedation
Muscle atrophy can occur when a patient's ventilation is totally controlled (they are not assisting the ventilator) for extended periods of time
True or false
true
Troubleshoot question
In volume control ventilation an increase in flowrate will cause a ?
decrease in I time
You are caring for a patient in NPPV with the following settings: IPAP=15, EPAP=5, Rise of 2, I-time of 0.8 seconds, FiO2=.60, their abgs are: pH=7.36, PaCO2=44, HCO3=24, PaO2=55, what is the most appropriate changes to correct the ABG?
increase EPAP but keep IPAP the same
You are caring for a patient with ARDS and their Plateau pressure is now up to 28cmh2o, with minimal PEEP the most appropriate action is?
Increase PEEP
