Q

4 Types of Pulmonary Function Studies

A

Forced vital capacity (FVC)- max amount of air that can be exhaled as quickly as possible after maximum inspiration. (decreased)

Forced expiratory volume (FEV)- max amount of air exhaled (decreased)

Peak expiratory flow rate (PEFR)- usually decreased

FRC (functional residual capacity) - the amount of air remaining in the lungs after normal expiration. (increased w/ air trapping i.e. emphysema)

Q

Other drugs for COPD

Mucolytics (Acetylcysteine, dornase alpha, guaifenesin) - 2
Oxygen - 2

A

Mucolytics (Acetylcysteine, dornase alpha, guaifenesin)
- thins secretions so easier to expectorate and cough up
- guaifenesin can raise cough threshold

Oxygen
- Usually oxygen flow of 2-4 L/min via nasal cannula or 40% via venturi mask
- ALL hypoxic patients should get oxygen therapy so SpO2 b/w 88-92%

COPD: Improving Endurance

Patient Education (5)

A
  • Avoid rushing in morning b-c can increase dyspnea

  • Avoid working w/ arms raised (raised arms reduce exercise tolerance b-c accessory muscles work to keep arms up instead of helping w/ breathing)
  • Do not talk during activities requiring energy (walking)
  • Avoid breath holding while performing any activity

Q

COPD: Breathing Exercises

  • Diaphragmatic/ abdominal breathing
  • Pursed-lip breathing (2)
A

Diaphragmatic/ abdominal breathing
- Patient consciously increases movement of diaphragm while lying on back to relax abdomen

Pursed-lip breathing
- Mild resistance created by breathing through pursed lips to prolong exhalation and increase airway pressure
- Delays airway compression and reduces air trapping

9 Nursing Care for chest tube system

A
  • Avoid kinks, Occlusions, or Loose Connections (should be straight)
  • Do NOT Strip/Milk Tubing
  • Keep Drainage System Below Level of Chest
  • Assess for “Tidaling” (water level rises inhalation and fall exhalation)
  • bubbling seen on exhalation, forceful cough, position changes (EXCESS BUBBLING = air leak)
  • Always have at least 2 cm of water to prevent air from returning to patient in water seal chamber
  • Limit clamping of a chest tube b-c will increase pressure in pleural space and may cause tension pneumothorax
  • No need to disconnect chest tube for transport
  • never let drainage come in contact w/ tubes (can cause tension pneumothorax)

  • Chest tube disconnects from the drainage system (first, put end of tube in a container of sterile water and keep below the level of the patient’s chest)
  • Drainage in tube stops (in the first 24 hours)

What are they?
How can it be prevented?

A

Hypoglycemia
