Quiz 2 Flashcards
It occurs when the patient’s minute ventilation cannot keep up with CO2 production.
Ventilatory Failure
It is the volume change per unit pressure change ()
lung compliance
ARDS, atelectasis, Tension Pneumothorax, obesity and retained secretions are the clinical conditions that under in? ()
Static Compliance
Give one clinical conditions under in dynamic compliance? (
Bronchospasm, kinking of ET tube, Airway obstruction)
It is defined as airflow obstruction in the airways. ()
Airway resistance
What is the normal airway resistance in healtht adults ranges from _ to _ H20/L/sec (
0.5 to 2.5 cm)
Airflow resistance of a patient-ventilator system may be monitored using the _____________ display on a ventilator waveform display.
pressure-volume (P-V) loop)
It is also known as high elastance, means that the volume change is small per unit pressure change.
Low Compliance)
- In clinical range, for critically ill patients their static compliance is between _____ and _____. (
40 and 60 mL/cm H2O
It reflects how effectively the lungs expand and contract during normal breathing. ()
Dynamic Compliance
A persistent low level of oxygen in blood that is not responsive to medium to high concentration of inspired oxygen. It is usually caused by intrapulmonary shunting.
refractory hypoxemia
The pressure used to deliver the tidal volume by overcoming nonelastic (airways) and elastic (lung paren- chyma) resistance.
peak inspiratory pressure:
