  • Small amount of blood tinged sputum is normal.
  • Turn the head to one side to prevent aspiration.

Complications

  • Bronchial perforation
  • Hemorrhage
  • Infection
  • Pneumothorax
  • cardiac arrhythmia

Pulmonary angiography

Study of pulmonary artery by introduction of die in to the pulmonary artery through the femoral or antecubital vein contract die is injected and serious of X-ray are taken.

  • Nurses Responsibility

  • Insertion site care.
  • Monitor temperature.
  • Increased fluid intake.
  • If femoral vein is used keep bed rest for 8 to 12hr

THORACENTESIS





Insertion of needle in to the thoracic cavity for removal of air or fluid in the plural place  

Nurses Responsibility

  • Informed consent.
  • Monitor vital signs.
  • Do coagulation study
  • Prepare the patient for X-ray or USG

Position during the procedure

Sitting up right at the edge of the bed and leaning forward on a cardiac table.

Non ambulating patient

Sidelining the affected side upward with 45degree head elevation.

Instruct the patient do not move or cough during the procedure

Post procedure

  • Insertion site care.

–     Monitor temperature

–     Pressured dressing should be applied to the side.

COMPLICATION

  • Pulmonary air embolism.

LUNG BIOPSY.

Tissue taken from the lung for histopathological study

Nurses Responsibility

  • Informed consent.
  • Monitor vital signs.
  • Do coagulation study.
  • Keep NPO.
  • Administer sedative.

Post op procedure

  • Apply pressured dressing.
  • Administer analgesic.
  • Monitor for complication

Complications

  • haemorrhage
  • pneumothorax

VENTILATION PERFUSION SCAN (Vq scan)

Ventilation means patency of the pulmonary airway. And perfusion evaluate blood supply to lung. For accessing the ventilation patient inhale a radioactive gas and serious of X-rays are taken to evaluate the perfusion. Radio isotope die is administered through vein in to the pulmonary artery and scanning is done.

Nurses Responsibility

  • Informed consent.
  • NPO
  • Access allergy to sea food and shell fish
  • Remove metallic object.

Post procedure.

  • Increase fluid intake.

  • Wash hands\after each voiding.
  • Double flush the bathroom after voiding

ABG VALUES ANALYSIS

  • Ph:                 35-7.45
  • Pco2: 35-45mm of hg
  • Po2: 80-100 mm of hg
  • Hco3: 22-29 mcq
  • O2 concentration: 90-100%

NURSING RESPONSIBILITY

  • Do Allen test before sample collection.
  • Collect blood from artery only.
  • Insert needle in degree.
  • Keep sample over ice piece.
  • Sent sample as soon as possible
  • Apply pressure for 5 minute.

PULS OXIMETER.

To determine oxygen concentration. Normal is 96-100%

NSG RESP

  • Apply sensor or probe to the finger, ear lobe, nose, and forehead.
  • Keep transducer at heart level.
  • Do not keep probe in extremity with impair circulation.
  • Remove nail polish.
  • Do not keep the probed extremity under light.

INCENTIVE SPIROMETRY

Used to access lung capacity. And to maintain lung expansion.

NSG RESP

  • Instruct the patient to sit upright and keep mouth piece tightly around mouth.
  • Inhale slowly to raise the flow rate indicator between 600-900 mark
  • Instruct the patient to hold the breath for 5 second and exhale through purse lips
  • Repeat the procedure 10 times/hours.
