Exam 1 Stuff Idk

Question 1

Weaning criteria for ventilator (numbers)
Vital capacity, max inspiratory pressure, tidal volume, breathing index, PaO2, and FiO2

Answer 1

Vital capacity: 10-15 ml/kg
Maximum inspiratory pressure at least -20cm H2O
Tidal volume: 7-9 ml/kg
Rapid/shallow breathing index: below 100 breaths/min/L
PaO2 >60 mmHg with FiO2 <50%

Question 2

Lab values indications for MV
PaO2, PaCO2, pH, vital capacity, negative inspiratory force, FEV1

Answer 2

PaO2: <55 mmHg
PaCO2: >50 mmHg
pH <7.32
Vital capacity <10 ml/kg
Negative inspiratory force: <25 cm H2O
FEV1 (forced expiratory volume of the 1st second): <10 ml/kg
