what is the difference between a closed and open loop ventilation system. -
(answers)closed loop has an inhalation and exhalation. open loop has only an
inspiratory limb with an exhalation valve
what term refers to how much effert the patient has to exert to trigger an
inspiration - (answers)trigger mechanism
flow triggering is used in which ventilation modes? - (answers)complete control
which type of triggering has a decreased risk of trauma to patient - (answers)flow
triggering
list and define the indications for MAV - (answers)respiratory insufficiency, acute
respiratory failure, apnea, refractory hypoxemia W.O.B, head trauma, severe
cases of COPD
a patient who is successful in achieving ventilation and oxygenation, but at such a
physical cost that their ability to maintain their status is short term and will
eventually lead to respiratory failure - (answers)respiratory insufficiency
any conditon in which respiratory activity is completely absent or is inadequate to
maintain oxygen reuptake and CO2 clearance - (answers)respiratory failure
, 2
what are the goals of MAV - (answers)to maintain adequate alveolar ventilation,
reduce W.O.B until cause can be determined, restore acid/bases balance, increase
oxygen
what are the common conditions which can cause respiratory failure -
(answers)myasthenia gravis, guillain-barre, ALS, drugs, pleura occupation, chest
wall deformities, conditions with increased RAW, interstitial fibrosis, aspiration
what are the respiratory causes of respiratory failure - (answers)tachypnea,
dyspnea, paleness/cyanosis
what are the cardiovascular causes of respiratory failure -
(answers)tachycardia/bradycardia, hypertension/hypotension, vasoconstriction,
and arrhythmias
what are the neurological causes of respiratory failure - (answers)restlessess,
disorientation, headache, lassitude, somnolence, confusion, delirium,
blurred/tunnel vision
what are the ventalitory values association with the need for MAV? - (answers)<8
and >35bpm, Vt <5ml/kg, VC <15mmHg, NIF/MIP -20 - 0, MEP <40, PEFR 75-100,
CO2 >55mmHg, pH <7.25, Vd,Vt >0.6
what are the oxygenation values indicative of the need for MAV? - (answers)PaO2
<70 on O2 > 0.6, A-a gradient >450 on O2, PaO2/PAO2 < 0.15, PaO2/FiO2 <200
