Breathlessness Flashcards
Definition
Uncomfortable need to breathe
3 pathophysiology of breathlessness
Simulation of intrapulmonary sensory nerves
Increased in mechanical loads of respiratory muscle
Simulation of chemoreceptors in hypoxia hypercapnia acidosis
Common pulmonary causes of dyspnea
COPD
asthma
Pneumonia
pulmonary embolism
pneumothorax
Cardiac disease causing Dyspnea
Congestive heart failure
Acute coronary syndrome
dysrhythmias
valvular heart disease
Stages of dyspnea
Exertional dyspnea
Orthopnea
Paroxysmal nocturnal dyspnea
Resting Dyspnea
Miscellaneous causes of dyspnea
Metabolic acidosis
severe anemia
pregnancy
hyperthyroidism
hyperventilation syndrome
