IPPB

Question 1

what does IBBP stand for

Answer 1

intermittent positive pressure breathing

Question 2

how long do you do IBBP for

Answer 2

15-20 minutes - short term

Question 3

how is the machine powered

Answer 3

pneumatically powered machine

Question 4

what happens to the alveoli due to IBBP treatment

Answer 4

increase in size bc of positive pressure

Question 5

what are the clinical goals of IPPB

Answer 5

need to improve lung expansion, need for short term ventilator support for hypercapnic patients, deliver medications

Question 6

physiology of IPPB

Answer 6

increase in mean airway pressure, decrease in work of breathing, manipulate the I:E ratio, increase in tidal volume, mechanical bronchodilation, secretion control, cerebral blood flow alteration

Question 7

indications of IPPB

Answer 7

acute or chronic hypoventilation, atelectasis, reduced cough effort, increased RAW, increased WOB, accumulation of secretions, pulmonary congestion/edema

Question 8

what is an absolute contraindication of IPPB

Answer 8

untreated tension pneumothorax

Question 9

hazards of IPPB

Answer 9

increased RAW, WOB, hemoptysis, psychological dependence, increased V/Q mismatch, air trapping, pneumothorax, bronchospasm, gastric distension, impede venous return, 02 induced hypoventilation, hyperventilation

Question 10

relative contraindications of IPPB

Answer 10

active hemoptysis, increased intercranial pressure >15 mmHg, hiccups, tracheoesophageal fistula, uncooperative patient, any facial/skull trauma, untreated active TB, blebs, hemodynamic instability

Question 11

effectiveness of therapy

Answer 11

tidal volume increased by more than 25%, breath sounds improved, PEFR/FEV1 increased, ABG improvement, secretion clearance increase, more effective cough, better x-ray evidence

Question 12

how does IPPB start

Answer 12

when it is triggered for sensitivity b/w -2 and -5 cmh2o

Question 13

how do you set the flow rate

Answer 13

watching pressure gauge and talking to the patient

Question 14

what do you set the pressure at

Answer 14

according to the prescribed tidal volume - 10 to 15 ml/kg ideal body weight and always below 20 cmh2o

Question 15

what happens when you increase sensitivity

Answer 15

the magnet is further away so it takes less breath to start the cycle and makes it easier

Question 16

`how do you increase pressure

Answer 16

have the magnet closer to the disk its harder because you have to break them apart

Question 17

how do you create volume

Answer 17

you create volume by increasing the pressure

Question 18

what will happen if the machine is too sensitive

Answer 18

it will autocycle to quickly and the magnet is to far away from the plate

Question 19

what will happen if the machine is to difficult

Answer 19

pt cant trigger and the manameter will swing negative but nothing will happen

Question 20

how can you tell if a patient is trying to breath with the machine

Answer 20

the manometer will have pressure jumps

Question 21

what does IPPB make the inspiration pressure become

Answer 21

positive instead of negative pressure

Question 22

when is the breath terminated

Answer 22

when the predetermined inhalation pressure is reached and then the patient can exhale

Question 23

what is the mean airway pressure

Answer 23

average of both pressures on exhalation and inhalation
