NSG 229 Exam 3 With
Complete Solution
Indications for mechanical ventilation - ANSWER hypoxia
apnea
respiratory muscle distress
acute resp failure (ARFs)
inability to breathe or protect the airway
negative pressure ventilation - ANSWER use of chambers that encase the
chest or body and surround it with intermittent subatmospheric or negative
pressure. it does not include the use of artificial airway
positive pressure ventilation (PPV) - ANSWER main method of ventilation
used with acutely ill patients.
Volume ventilation - ANSWER A predetermined tidal volume (Vt) is delivered
with each inspiration
Vt is consistent from breath to breath but the airway pressures needed to
deliver the Vt will vary
pressure ventilation - ANSWER peak inspiratory pressure is predetermined
Vt delivered varies based on pressure selected
monitor exhaled Vt to prevent hypoxemia and hypoventilation
,adjustable ventilator settings - ANSWER respiratory rate - # breaths per
minute
tidal volume - volume of gas delivered per breath
O2 concentration (FiO2)
PEEP - positive end-expiratory pressure
pressure support
I/E ratio
inspiratory flow rate and time
sensitivity
PIP - peak inspiratory pressure
what is O2 concentration on mechanical vent - ANSWER fraction of inspired
O2 (FiO2) delivered
set between 30% and 100%
you would never intubate and place on room air (21%)
what is PEEP - ANSWER a vent setting that gives positive end expiratory
pressure
positive pressure applied at the end of expiration of vent
apnea alarm causes - ANSWER change in patient condition
increased WOB
loss of airway
over-sedation
, respiratory distress
apnea alarm interventions - ANSWER increase analgesia and sedation
change mode of ventilation
disconnect patient, attach BVM and call for help
high pressure alarm causes - ANSWER increase in compliance (pulmonary
edema, ARDS, pneumonia, tension pneumo)
condensation in tubing
kink in tubing (can also be from patient biting tube)
increase in resistance (bronchospasm)
high pressure alarm interventions - ANSWER suction patient
unkink tubing
insert bite block
administer bronchodilator
assess breath sounds/order chest x-ray
remove water from tube
administer analgesia and sedation
high VT, resp rate or minute ventilation alarm causes - ANSWER anxiety or
pain
change in condition
