Lungs Flashcards
What is Scattered ronchi and what causes it?
- Breath sounds associated with COPD and is caused when there are secretions or obstructions is the large airways
What are crepitations and what causes them?
- Abnormal sounds heaved over the lungs caused bya subcutaneous emphysema or rupture in the airway
Why does a patient uses accessory inspiratory and expiratory muscles ?
Because the person is unable to breath out enough air and the accessory muscles are activated automatically
Can occur in patients with COPD
Cyanosis

Bronchodilators efficacy and categories
Long acting have been able to produce an improvement inlung function and quality of life and prevents relapses in patients with COPD, reduce hyperinflation and therefore improve dyspnea and increase latesince tophysical activity.

Normal levels of oxygen in the blood
75-100 mmHg
cower than 60 mmHg will need supplemental O2
What is O2 saturation and how do we determine it?
measures how well oxygen the haemoglobin is carrying
and is determined by the pulse oximeter
