  1. describe the different oxygenation criteria for nasal cannula, face masks, non-rebreathers, venturi masks and face tents
    • Nasal Cannula: 1-6 L/min, common skin breakdown behind ears
    • Simple Facemask: 40-60% O2 equal to about 5-8L/min. Make sure it fits
    • Partial Rebreather: 60-75% O2 equal to about 6-11L/min. Rebreaths about 1/3 of exhaled volume
    • Non-rebreather: Provides the highest amount of O2 at above 90%.  Flaps over exhalation port vent out CO2 and need to be checked to prevent aspiration
    • Venturi mask: delivers a set percentage of oxygen. Best delivery before intubation.  Combines RA with O2
    • Fact tent: provides high humidity with O2
  2. What is a CPAP?
    • Continuous Positive Airway Pressure
    • Mild air pressure to keep airway and alveoli open during the entire respiratory cycle, commonly used for sleep apnea

    • A fenestrated tracheostomy tube may be used in the future to restore verbal communication
  5. What is a PE? what are the risk factors?
    • An air bubble, plaque, fat or clot that lodges in the pulmonary vessels and prevent oxygenation and gas exchange
    • A large clot can be fatal
    • Usually begins as a thromboembolism (DVT is common) or a thrombosis, air bubble from large IV tubing
    • Risk factors: immobility, advanced age, hist of DVT, surgery to pelvis or long bones, gastric bypass, central lines, nonadherance to anticoags

    • Used to maintain a patent airway, remove sections and provide ventilation (oxygen)
    • The tip of the tube rests just above the carina, cuff of the tube seals the trachea when pilot balloon is filled with area
    • Correct placement done by c-ray or CO2 (gold standard)
    • Chest rise and sounds should be equal bilat when done correctly
    • Nasal intubations used for clients have oral surgery, distorted oral anatomy or with maxillofacial trauma

    • Provide frequent oral care
    • Restrain pt if appropriate
    • *Fistula can develop between esophagus and traches
  18. Describe positive pressure ventilation and BiPAP
    • Positive pressure: pressure is pushed into the lungs and expands the chest. Uses an ET tube
    • BiPAP: provides noninvasive positive pressure support by nasal mask or face mask. Often used for sleep apnea
  19. What is PEEP?
    • Positive end expiratory pressure
    • positive pressure exerted during expiration
    • Prevents atelectasis because lungs are kept partially inflated
    • Gas exchange in promoted throughout respiratory cycle
  20. What is the nursing care for a client with mechanical ventilation?

  25. Describe chest tube placement and purpose
    • Insertion of tube into the pleural space between visceral and parietal pleurae
    • Purpose: evacuate air or fluid, regain negative pressure
    • Mechanical systems can use a single bottle water seal system or a three bottle water seal system
  26. describe how a chest tube drainage system works
    • First section (bottle 1) drains air or fluids from client
    • Second section (bottle 2) prevents air or water from moving back into the client. section contains water. This section should bubble initially until air has been evacuated from the pleural space and then the bubbling stops.  Water will rise and fall with inspir/expir (tidaling)
    • Third section (bottle 3) is connected to suction at the wall. This should bubble gently.  Contains water
  27. What are the nursing interventions for chest tube drainage?
    • Assessment of respirations- rate, rhythm, depth, anterior, posterior, lung bases
    • Monitor vital signs
    • Assessment of chest tubes (mark placement on tube) and drainage system 
    • Assess puncture site
    • Admin pain medications
  28. What is the protocol for chest tube removal?
    • Supplies needed: sterile gloves, goggles, mask, gown, chux, vaseline gauze, tegaderm, sterile suture removal kit, rubber tipped hemostats, occlusive tape
    • Admin pain medication
    • Place the client in semi fowlers and put chux under tube site
    • After dressing is removed and sutures are cut, MD clamps tube
    • Instruct patient to perform valsalva or hold breath
    • MD removes tube and occlusive (vaseline) dressing is immediately placed
    • VS q15min for 1 hr, q30min for next 2hrs, then q1hr for 4hrs
