What is the RTs first priority when an alarm is activated on a ventilator? |
Ensure adequate oxygenation and ventilation |
|
|
Removing a patient from a manual ventilator to ventilate manually can lead to what complications? |
Barotrauma Derecruitment of the lungs VAP |
|
|
Patient is bagged through ETT, bag is difficult to squeeze. Breath sounds are present on right but absent on the left. Percussion reveals hyperresonant over the left lung. What intervention should be done? |
Pneumothorax on the left perform needle decompression with 14 gauge needle |
|
|
Ventilator is sounding low pressure, low exhaled Vt, and low VE alarms, what could be happening? |
Leaks Patient disconnect Rupture of ETT cuff ETT has migrated into upper airway |
|
|
What is the initial step in the management of patient-ventilator asynchrony? |
Disconnect patient and manually ventilate |
|
What is seen on the scalar and how should it be fixed? |
Obstruction Administer bronchodilator Suction Pt. |
|
What is the problem? |
Inadequate flow |
|
What is the problem? |
Leak in the system |
|
What is the problem? |
Active inspiration |
|
|
How do you stop a hemorrhage from an innominate artery rupture caused by insertion of a trach? |
Overinflate cuff Apply internal pressure with a finger through stoma |
|
|
What ventilator settings can be changed in AC-VC to correct respiratory acidosis? |
Increase Vt in increments of 50ml Increase RR in safe range of 10-18bpm (15-25 for ARDS) |
|
|
What can be changed in AC-PC ventilation to correct respiratory acidosis? |
Increase PIP |
|
|
A patient has respiratory alkalosis due to high VE, what can be changed in AC-PC to correct this? |
Evaluate cause Decrease RR Decrease PIP |
|
|
A patient is alert and awake and is over breathing the ventilator which is on AC-VC and is causing respiratory alkalosis, changing to what kind of mode can help normalize the ABG? |
SIMV with PSV |
|
|
Define permissive hypercapnia |
Deliberate limitation of ventilatory support to avoid lung overdistention and injury allowing PaCO2 to rise and pH to fall Used for ARDS |
|
|
At what point during deep suctioning should negative pressure be applied? |
Insert catheter until resistance is met then withdraw 1cm before applying pressure |
|
|
While using a SVN or pMDI with NPPV, where in the NPPV circuit should the device be placed to obtain the greatest aerosol deposition? |
Between the leak port and the mask |
|
|
After a bronchosopy a patient is not arousable, what can be done? |
Administer Narcan (Naloxone) or Romazicon |
|
|
What is the normal ratio for VD/VT? |
0.2 - 0.4 |
|
|
What can cause a high-pressure alarm? |
Coughing Secretions Biting ETT Kinking ETT or circuit Position change of ETT Herniation or impingement of ETT Increased Raw Decreased complince Patient-ventilator asynchrony Accumulation of water in tubing Machine malfunction |
