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
