respiratory pattern Flashcards
what is tachypnoea?
resp rate >25 breaths/min
what is tachypnoea caused by
increased ventilatory drive in fever, acute asthma and exacerbation of COPD
or reduced ventilatory capacity in pneumonia, pulmonary oedema and ILD
what is bradypnoea?
resp rate <10 breaths/mnin
what is bradypnoea caused by?
opiod toxicity
hypercapnia
hypothyroidism
raised intracranial pressure
what is kussmaul respiration and what is it associated with?
hyperventilation with deep, sighing respirations occurs in metabolic acidosis caused by DKA, acute renal failure and lactic acidosis
what is apnoea
absence of breathing
what is hypopnoea
reduction in airflow or respiratory movements by >50%
what is OSAHS
obstructive sleep apnoea/hyponoea syndrome
combination of excessive daytime sleepiness and recurrent upper airway obstruction with sleep fragmentation caused by upper airway obstruction from collapse of the retropharynx
