mechanical Ventilation exam 1 questions
with answers
what is pip? - ANSWER: ✔✔total pressure required to deliver the breath
what is Auto Peep? - ANSWER: ✔✔air trapping in lung during mechanical ventilation
What is Plateau pressure? - ANSWER: ✔✔pressure that required to keep alveoli inflated
indication for mechanical ventilation - ANSWER: ✔✔- apnea
- acute ventilatory failure/ arrest
- impending ventilatory failure
- severe hypoxemia
hazards and complication of PEEP - ANSWER: ✔✔- barotrauma
- pneumothorax
- ICP
- negative cardiovascular effects
contraindications for PEEP/CPAP - ANSWER: ✔✔- hypovolemia
- Barotrauma
- increase ICP
- untreated pneumothorax
- unilateral lung disease
what is Optimal PEEP? - ANSWER: ✔✔PEEP levels that have acceptable parameters
, indications for ABG - ANSWER: ✔✔- Sudden unexpected dyspnea
- cyanosis
- abnormal breath sounds
- heavy use of accessory muscles or sever tachypnea
- diffuse infiltrate in CXR
- CPR
Changes in Vent settings
steady state for ABG - ANSWER: ✔✔- when pts is placed on O2 or vent,
Sites for ABG - ANSWER: ✔✔- Radial
- Brachial
- Femoral ( physicians only)
modified Allen Test? - ANSWER: ✔✔Pt asked to clench fist; then put pressure with fingures on their
radial and ulnar aa; should see blanching(white); then release ULNAR artery and hand should flush pink
approx 5-15 seconds; means ulnar circulation is good; (+allens test)
Monitoring on ABG - ANSWER: ✔✔- FiO2
- Proper application of O2 device
- Mode and Vent settings
- Pulsatile blood setting
plateau - ANSWER: ✔✔pressure measured where there is no gas flow
functional residual capacity - ANSWER: ✔✔total amount of gas remaining in the lung after resting
expiration
the cause of mechanically ventilated patients PIP increase from 20 to 40cmH2O while the static
compliance remains relatively unchanged is which of the following?
