Question | Answer |
Normal pressures in the cuff should be kept in which range? | 15 to 20 mmHg |
Normal arterial Po2 levels (at sea level) fall within which of the following ranges? | 80 to 100 mmHg |
Normal venous Po2 levels (at sea level) fall within which of the following ranges? | 35 to 40 mmHg |
Normal arterial hemoglobin saturation (SaO2) falls within which of the following ranges? | > 0.95 |
Normal mixed venous hemoglobin saturation (Svo2) falls within which of the following ranges? | 0.60 to 0.80 |
What worsen dynamic compliance? | A.OBESITY B. AIRWAY SECRETIONS C. THIRD-TRIMESTER PREGNANCY |
VITAL CAPACITY | MAXIMAL INSPIRATION FOLLOWED BY MAXIMAL EXPIRATION |
DEAD-SPACE VENTILATION | THE AMOUNT OF AIR THAT DOES NOT PARTICIPATE IN GAS EXCHANGE. |
ALVEOLAR VENTILATION | MINUTE VOLUME MINUS DEAD SPACE VENTILATION |
NORMAL DEAD SPACE LEVEL | 25% TO 35% |
THE MOST COMMON CAUSE OF HYPOXEMIA? | INTRAPULMONARY SHUNTS |
AN ESTIMATE OF INTRAPULMONARY SHUNTING | Pao2/FiO2 ratio |
FiO2 (fraction of inspired oxygen) | THE PERCENT OF OXYGEN DURING INSPIRATION |
Normal oxygen tension (Pao2) on exposure to 100% oxygen | 400 to 600 mmHg |
Intrapulmonary shunting ranges | 0 to 5% |
Which parameter is used as an estimate of alveolar ventilation (Va)? | Paco2 |
At which pH is an acidosis generally treated? | < 7.25 |
How is the pulmonary artery occlusive pressure (PAOP) used in differentiating ARDS from cardiogenic-induced pulmonary edema? | A low PAOP with large intrapulmonary shunts suggests ARDS. |
Oxygen toxicity is thought to develop with which level of FiO2? | > 50% for longer than 24hrs |
What is an indication for PEEP therapy? | TO ALLOW REDUCTION IN FiO2 LEVELS |
PRESSURE-SUPPORT VENTILATION (PSV) differs from synchronized intermittent mandatory ventilation (SIMV) and AMV in which ways? | SIMV and AMV are volume-limited, PSV is pressure-limited. |
What is a complication of mechanical ventilation and PEEP therapy? | REDUCED CARDIAC OUTPUT |
What is the highest FiO2 that can generally be achieved with a nasal cannula? | 40% |
What condition produces both ventilation and perfusion disturbances? | CHRONIC BRONCHITIS OR COPD |
In a pleural drainage system what indicates an active pleural leak? | BUBBLING IN THE WATER-SEAL CHAMBER |
What condition may lead to a tension pneumothorax? | CLOSED PNEUMOTHORAX |
Which finding would be an indication of a ruptured diaphragm? | BOWEL SOUNDS IN THE CHEST |
