Q

Vent Settings: Assist Control

A
  • does everything for the patient (when the patient is too weak to perform spontaneous breathing)
  • usually used when patient is first intubated
32
Q

Vent Settings: Respiratory Rate

A
  • minimum amount of breaths the patient will be able to take
  • often set between 12-18
  • rate would be higher if the patient needs to blow off CO2
33
Q

Vent Settings: Tidal Volume

A
  • amount of air that will go into the patient’s lungs with each breath
  • based on the ideal body weight of the patient (10mL/kg)
  • may be less d/t poor lung compliance
34
Q

Vent Settings: FiO2

A
  • amount of oxygen being delivered
  • room air = 21%
35
Q

Vent Settings: PEEP

A
  • increases end-expired lung volume and reduces airspace closure at the end of expiration
  • unnatural breathing and feels strange for patient
  • PEEP that is too high can cause a pneumothorax, barotrauma, decreased cardiac output, and decreased BP
36
Q

Ventilator Alarm Reasons: High Pressure

A
  • secretions, coughing, or gagging
  • asynchrony (fighting the vent, biting tube, etc.)
  • water in the tubing (dump out the tube)
37
Q

Ventilator Alarm Reasons: Low Pressure

A
  • disconnect from the vent
  • partial or complete extubation
38
Q

Ventilator Alarm Reasons: Apnea

A
  • change in condition
  • loss of airway
39
Q

Nursing Interventions: Promoting Effective Airway Clearance

A
  • assess lung sounds at least every 2-4 hours
  • measures to clear airway: suctioning, CPT, position changes, promote increased mobility
  • humidification of airway
  • administer bronchodilators and mucolytics
  • suctioning only if excessive secretions
  • check for oral ulcers
40
Q

Nursing Interventions: Preventing Injury and Infection
