-
ippb is a short term breathing treatment which provides
pressures to be dilivered to the pt's lungs via pressure limited ventilator
-
what is meant by increased mean airway pressure
the avg mean presure in the airways during one breathing cycle
-
what is lung compliance
"bounce back of the lungs" indication of elastic recoil of the lung
-
to prevent pt from experiencing light-headedness, dizziness or faintness from reduced paco2 levels, encourage the pt to
breathe slowly and to pause between breaths
-
airway resistance is a narrowed
bronchioles. ex: asthma
-
lung compliance is the
bounce back of the lungs. indication of the loss of elastic recoil of the lungs
-
what are some types of indications for ippb therapy
- inc wob
- hypoventilation
- pt who cannot take a deep breath
- inadequate cough
- inc airway resistance
- atelectasis, esp in sedated postop pt and pt recovering from chest or abdominal surgery
- pulm edema
-
list some hazards of ippb
- excessive ventilation/oxy
- dec CO
- inc icp
- pneumothorax
- hemoptysis
- gastric distention
- nosocomial infection
-
if the ippb is given with o2 with copd pt, it may elevate the pao2 abouve normal level (50-60) which may
knock out the pt's drive to breathe
-
how do u prevent an inc icp
use low pressure and shorter itime and have pt position in the fowler or sitting up position
-
pt who complains of sudden chest pain, sob, tachy, must be suspected with having
pneumothorax and treatment must be stopped immediately
-
what should u do if pulse rate eincresease more then 20 bpm
stop treatment and notify dr
-
how would u instruct a pt using a ippb
tight lip seal, allow the machine to fill the lungs until it cycles off,
hold breath for a count of threee before exhaling to better med delivery and improve gas exhange.
pause before the next breath
-
what is the goal of is
- to prevent atelectasis (collapse lung/alveoli)
- treat pre-existing atelectasis
- to imp cough
- maintain airway during preoperative period
-
hazards of is
- hyperventilation
- pneumothorax
- inc icp and stimulation of the vagal nerve reflex
-
how to instruct pt to use the is
- hold the is in a upright position
- tight seal on mouth piece (use nose plugs if theres a leak)
- INHALE slowly and as deeply as possible.
- hold breath for 3-5 sec then remove mouthpiece and exhale normally
- rest n breathe for 30 sec
repeat 8 to 10x's per waking hour
