Week 3: Respiratory Conditions & Management Flashcards
Define hyperventilation
Fast and/or deep breathing
Define hypoventilation
Slow and/or shallow breathing
Define apnoea
Absent breathing/no breathing rate
Define heamoptysis
bleeding from respiratory tract below larynx
Define dyspnoea
Difficult or uncomfortable breathing
Define orthopnoea
Breathless when lying down, relieved by sitting or standing
Define PND
Paroxysmal nocturnal dyspnoea- a sensation of breathlessness that wakes the patient, often after 1-2 hours of sleep, usually relieved in the upright position
Define hypoxia
Hypoxia is the deficiency in the amount of oxygen reaching the tissues and cannot maintain adequate homeostasis
What are causes of hypoxia?
- poor oxygen delivery to tissues
- decreased alveolar PAO2
- diffusion impairment
- V/Q mismatch
- haemoglobin abnormalities
- poor cardiac output
What factors can influence respiration rate?
-Disease, exercise, shock, sleep, smoking, age, speech/singing, emotional displays, drugs
What are symptoms of asthma?
- audible expiratory wheeze
- increased work of breathing
- tachypnoea
- dyspnoea
- tachycardia
- reduced SpO2
- coughing
- chest tightness
What are possible asthma triggers?
infections, house dust mites, pollen and spores, animals, exercise, cold air, drugs, foods, pregnancy, emotion, deep inhalation
What causes asthma?
Bronchioconstriction
- chronic inflammation of bronchi makes them narrower
- excessive suptum
- hypersensitive airways
How would you manage asthma?
- oxygen therapy
- nebulised salbutamol
- prednisolone/hydrocorisone
What is the main stimulus to breathe for a patient with COPD?
Hypoxia
What does the term COPD cover?
- Chronic asthma
- Chronic bronchitis
- Emphysema
