the most common diagnosis requiring mechanical ventilatory support:
|
1. acute respiratory failure
2. COPD exacerbation |
|
the 4 therapeutic goals of mechanical ventilation:
|
-- to maintain adequate alveolar ventilation.
-- to maintain oxygen delivery. -- to restore acid-base balance. -- to reduce the work of breathing with minimal harmful side effects and complications |
|
lists 3 advantages of negative pressure ventilation:
|
-- the lack of need for an artificial airway.
-- relative simplicity. -- ease of use of the devices |
|
list 3 situations in which noninvasive positive pressure ventilation should be considered:
|
-- in the management of acute exacerbation of COPD.
-- management of acute cardiogenic pulmonary edema. -- the treatment of patients who are prematurely extubated after conventional mechanical ventilation |
|
inability to tolerate the nasal or oral mask,
poor mask fit, secretion problems, severe hypoxemia, severe acidosis, hypotension, and upper airway obstruction are all related to: |
contraindications for the use of noninvasive positive pressure ventilation
|
|
in PSV, what cycles off inspiration?
|
flow
|
|
disadvantages of assist control mode include:
|
-- an increase in the work of breathing with inappropriate sensitivity and flow settings
|
|
-- anxiety.
-- pain. -- hypoxemia. -- metabolic acidosis -- inappropriate ventilator settings....... can all lead to: |
a patient raising their respiratory rate
|
|
pressure control ventilation is selected in which situations:
|
-- for patients who have poor results, with volume control.
-- when limiting the plateau pressure is a concern. -- in the care of patients expected to need prolonged inspiration (typically ALI or ARDS patients) |
|
the maximum suggested a rate to achieve the desired pH in adult patients in pressure control mode is:
|
35 breaths per minute
|
|
-- improved gas distribution.
-- decreased hyperinflation of compliant alveoli. -- sustained inspiration pressure may result in more alveolar recruitment. -- lower peak inspiratory pressure. -- variable flow is able to compensate for small air leaks, are all: |
advantages of pressure control ventilation
|
|
-- higher mean airway pressure that can decrease in venous return and cardiac output.
-- varying tidal volumes based on lung compliance, resistance, and patient effort. -- if tidal volume or minute ventilation alarms are not set properly, alveolar hypoventilation and acidosis may not be detected, are all cases of: |
disadvantages of pressure control ventilation
|
|
VAPS stands for:
|
volume assured pressure support
|
|
PRVC stands for:
|
pressure regulated volume control
|
|
what protective lung strategy is should be used when a plateau pressure is approaching 30 cm H2O?
|
the pressure limit or the tidal volume should be decreased
|
|
air trapping during positive pressure ventilation is often referred to as:
|
--dynamic hyperinflation
-- auto PEEP. -- occult PEEP. -- intrinsic PEEP |
|
--V/Q mismatch
-- shunt -- alveolar hypoventilation. -- diffusion impairment. -- decreased inspired O2. -- Venus admixture are all causes of: |
acute respiratory failure
