Desensitization, CPAP and BIPAP

What does desensitization do?

• reduced stress levels

• education

• sense of control

What is dyspnea

• breathlessness

• sensation and motor output

• air hunger, increased WOB, chest pain

What is pacing

• 2 steps, breath in

• 3 steps, breath out

• energy conservation, reduces fatigue

• avoids boom and bust cycle

What is fan therapy?

• used for dyspnoea

• air stimulates trigeminal nerve

• reduces sensation of breathlessness

What is blow as you go?

• Active Phase of Ex - exp

• Passive Phase of ex - insp

What is pursed lip breathing + its effects

• o shaped on expiration

• hands on abdomen

• blowing out a candle

• prolonged exhalation prevents air trapping

• reduced RR, WOB and muscle fatigue

• improved GE

• back pressure in airways = PEEP

• maintained oxygenatiom

• reduced dynamic hyperinflation

• improved breathing pattern

What is CPAP?

• continuous positive airway pressure

• delivery of continuous flow

• increased FRC by splinting alveoli open = increases oxygenation

• treats hypoxaemia

• reduced WOB

• increases SA for GE

• doesn’t improve VT - unhelpful for hypercapnia

What is BiPAP

• bilevel positive airway pressure

• 2 pressures - P and N

• splinting alveoli and flushing out co2

• oxygenation, reduced WOB

• reduced hypercapnia

• VQ match
