Topic 20 - Dyspnoe Flashcards
What is dyspnoea?
caused by difficulties of respiration
Name the different types of dyspnea:
- Inspiratory
- Expiratory
- Mixed
What is inspiratory dyspnoea caused by?
- Narrowed upper airways
- Pneumothorax
- Pleural effusions
- Diffuse pneumonia
Signs of inspiratory dyspnea:
Prolonged and labored inspiration
- Extension of head and neck
- Nostril dilation
- Labial respiration: breathing through mouth
- Slack of slunken flanks
- sagging belly
Inspiratory dyspnea have a … respiratory pattern?
Restrictive
What is expiratory dyspnoea caused by?
-compression or obstruction of lower air passages
-microbronchitis
-(pulmonary emphysema)
-fibrous pleuritis
-rarely neoplasms in larynx and pharynx
Signs of expiratory dyspnea:
Prolonged and labored expiration
- Work of abdominal muscles are more severe
- Extension of head and neck
- thorax is fast to collapse during expiration
Expiratory dyspnea have a … respiratory pattern?
Obstructive
What is mixed dyspnea caused by?
-decreased compliance
-pulmonary edema
-pulmonary emphysema
-neoplasma
-compressed diaphragm
Signs of mixed dyspnea:
Forced inspiration and expiration
Name the different respiratory patterns due to lung disease:
Restrictive and obstructive
What is restrictive respiratory pattern?
= difficulty filling the lung completely
the INHALATION is laboured
Signs of restrictive respiratory pattern:
Shallow breathing
Tachypnoea
Laboured breathing
What is obstructive respiratory pattern?
Difficulty to expel the air from the lungs, causing increased residual volume
The EXHALATION is laboured
