  • Nursingbullets: ARTERIAL BLOOD GASES
    • 1. Description: measurement of the dissolved oxygen and carbon dioxide in the arterial blood to reveal the acid-base state and how well the oxygen is being carried to the body

  • Nursingbullets: PULSE OXIMETRY
    • 1. Description
    • a. Pulse oximetry is a noninvasive test that registers the oxygen saturation of the client’s hemoglobin.
    • b. This arterial oxygen saturation (SaO 2 ) is recorded as a percentage.
    • c. The normal value is 95% to 100%.
    • d. After a hypoxic client uses up the readily available oxygen (measured as the arterial oxygen pressure, PaO 2 , on ABG testing), the reserve oxygen, that oxygen attached to the hemoglobin (SaO 2 ), is drawn on to provide oxygen to the tissues.
    • e. A pulse oximeter reading can alert the nurse to hypoxemia before clinical signs occur.
    • 2. Procedure
    • a. A sensor is placed on the client’s finger, toe, nose, ear lobe, or forehead to measure oxygen saturation, which then is displayed on a monitor.
    • b. Maintain the transducer at heart level.
    • c. Do not select an extremity with an impediment to blood flow.
    • d. Results lower than 91% necessitate immediate treatment.
    • e. If the SaO 2 is less than 85%, the tissues of the body have a difficult time becoming oxygenated; an SaO 2 of less than 70% is life threatening.
  • Nursingbullets: CHEST PHYSIOTHERAPY
    • Best time - morning upon arising, 1 hr before meals or 2-3 hrs after meals
    • Stop if pain occurs
    • Provide mouth care
    • CONTRAINDICATIONS OF CHEST PHYSIOTHERAPY (CPT)
    • Increased respiratory distress
    • History of fractures
    • Chest incisions
    • POSTURAL DRAINAGE: use of the gravity
    • NURSING CARE
    • Position the client
    • Best time – A.M. upon arising, 1 hr before meals, 2-3 hrs after meals
    • Stop if cyanosis or exhaustion occurs
    • Maintain position 5-20 mins after
    • Provide mouth care after the procedure
    • CONTRAINDICATIONS OF POSTURAL DRAINAGE
    • Unstable V/S
    • Increased ICP
    • CLIENT INSTRUCTIONS FOR INCENTIVE SPIROMETRY
    • Use the lips to form seal around the mouth piece
    • Inspire deeply
    • Hold inspiration for a few seconds
    • Forcefully exhale
    • Avoid the use of spirometry at mealtime - it may cause nausea
  • Nursingbullets: Chest Tube Thoracotomy
    • Chest Tubes/Water seal drainage
    • Insertion of a catheter into the intrapleural space to maintain constant negative pressure when air/fluid have accumulated
    • Chest tube is inserted to underwater drainage to allow for the space of air/fluid and prevent reflux of air into the chest
    • For evacuation of air, chest tube is placed in the second or third intercostal space, anterior or midaxillary line (air rises to upper chest)
    • For drainage of fluid, chest tube is place in the eight or ninth intercostal space, midaxillary line.
    • Chest tube is connected to tubing for the collection system; the distal end of the collection tubing must be placed below the water level in order to prevent atmospheric air from entering the pleural space.
    • Drainage system: water-seal drainage system can be set up using one, two, or three bottles; or a commercial, disposable device (e.g., Pleur-evac) may be used.
  • One-Bottle System
  • 2. Two-bottle system
    • a. One bottle serves as a drainage collection chamber, the other as a water seal.
    • b. The first bottle is the drainage collection and has two short tubes in the rubber stopper. One of these tubes is attached to the drainage tubing coming from the client; the other is attached to the underwater tube of the second bottle (the water-seal bottle). The air vent of the water-seal bottle must be left open to the atmospheric air. If suction is used, the first bottle serves as drainage collection and water-seal chamber, and the second bottle serves as the suction chamber
  • Two-way Bottle System
    • Nursing care: without suction
    • 1. Examine the entire system to ensure air tightness and absence of obstruction from kinks or dependent loops of tubing
    • 2. Note oscillation of the fluid level within the water-seal tube. It will rise on inspiration and fall on expiration due to changes in the intrapleural pressure. If oscillation stops and system is intact, notify physician.
    • 3. Check the amount, color, and characteristics of the drainage. If drainage ceases and system is not blocked, assess for signs of respiratory distress from fluid/ air accumulation
  • Three-Bottle System
    • a. This system has a drainage collection, a water seal, and a suction-control bottle.
    • b. The third bottle controls the amount of pressure in the system. The suction control bottle has three tubes inserted in the stopper, two short and one long. One short tube is joined with the tubing to former air vent of the water-seal; the second short tube is connected to suction. The third (long) tube (or suction-control tube) is located between the short tubes and has one end open to the atmosphere and other below the water level.
    • Nursing care: with suction
    • 1. Attach suction tubing to suction apparatus, and chest catheter to drainage system
    • 2. Open suction slowly until a stream of bubbles is seen in the suction chamber. There should be continuous bubbling in this chamber and intermittent bubbling in the waters seal. Check for an air leak in the system if bubbling in water seal is constant; notify physician if air leak
    • 3. Check drainage, keep drainage system below level of client’s chest, keep Vaseline gauze at bedside, encourage coughing and deep breathing, and provide ROM
    • 4. Always keep drainage system lower than the level of the client’s chest
    • 5. Keep Vaseline gauze at bedside at all times in case chest tube falls out
    • 6. Encourage coughing and deep breathing to facilitate removal of air and drainage from pleural cavity
    • 7. Never clamp chest tubes.
    • 8. Removal of the chest tube: instruct the client to perform Valsalva maneuver; apply Vaseline pressure dressing to the site
    • 9. If the water-seal bottle should break, immediately obtain some type of fluid-filled container to create an emergency water seal until a new unit can be obtained
