atelectasis

lungs that are collapsed or airless, loss of lung volume due to failure of the alveoli to properly expand.

atelectasis
most significant factor of atelectasis
- COPD
- -creates the need for pre-surgical pulmonary screening for abdominal or thoracic surgical procedures
5 predisposing factors of atelectasis
- obesity
- old age
- smoking history
- anesthesia
- history of heart or lung disease
3 types of PFT reductions
- reduction in FRC (functional residual capacity)
- reduction in VC (vital capacity)
- reduction of lung compliance
perfusion to affected area usually remains
normal
- v/q mismatching occurs
- -perfusion w/out ventilation
- -results in hypoxemia
typical signs and symptoms of atelectasis (dependent on severity)
- dyspnea
- tachypnea
- cough
- deviation of mediastinum/trachea TOWARD affected area
- elevation of diaphragm
- dullness to percussion
- accessory muscle use
breath sounds heard with atelectasis
- bronchials and diminished over affected area
- late ins crackles - represents sudden opening of atelectasis regions
mediastinal shift towards which side?

affected side
radiographic findings in atelectasis
- inc density in areas of atelectasis
- air bronchospasms
- elevation of the hemidiaphragm on the affected side
ABGs
- hypoxemia
- -causes resp alkalosis
treatment for atelectasis
- hyperinflation
- -IS
- -IPPB
- -CPAP or PEP
- -deep breathing or coughing
- secretion removal
- -CPT
- -suction
- -hydration and humidification
- -rotating/vibrating bed
