Breathing And Obstructive Lung Disease Flashcards
What is breathlessness
An awareness of the intensity of breathing
What is dyspnoea
This is the medical term for breathlessness and is the difficulty breathing at a time where difficulty should not be accepted
What is tachypnoea
Rapid breathing
What is hyperventilation
Breathing in excess of metabolic requirements, resulting in a decrease if CO2 levels in the blood
What is Orthopnoea
Medical term to describe difficulty breathing whilst lying flat. This condition is associated with heart failure. It also occurs in conditions like COPD, asthma, obesity or conditions that cause chest wall deformity.
What is SOBAR
Shortness of breath at rest refers to difficulty breathing whilst at rest, without any physical exertion or activity.
What is paroxysmal nocturnal dyspnoea
Sudden episodes of severe shortness of breath that wake a person from sleep, often after a few hours of falling asleep. It is associated with heart failure or other cardiac conditions.
What is SOBOE
Shortness of breath on exertion. Very self explanatory
Why is it hard to diagnose the mechanism of breathlessness
- no specialised receptors
- no identified area of the cortex
- no single easy identifiable stimulus
- very subjective sensation, based on experience.
What are some sensations of breathlessness
Rapid breathing
Shallow breathing
Increased work
Chest tightness
Heavy breathing
What is hypoxia
When there is a deficiency of oxygen supply to the tissues in the body. This can impair normal cellular function and lead to various health problems
Is hypoxia and breathlessness related always
No - people with low O2 are not necessarily dyspnoeic and people with normal O2 often complain of dyspnoea maybe due to obstruction of airway, just not lack of O2. However if hypoxia is prolonged then it often leads to dyspnoea
What is hypercapnia
A condition where the body has an excess of CO2 and the body’s ability to remove the CO2 is impaired.
What are some abnormal breathing oatterns
Use of accessory muscles
Rapid shallow breaths
Nasal flaring
Paradoxial breathing
Pursed lip breathing
Breath holding on activity
What are some treatments for breathlessness
Relaxation techniques
Positioning
Cognitive therapy
Aerobic exercise
Pacing
