Q

What might reduce the amount of air in the lungs?

A

Atelectasis/collapse- alveoli, segment, lobe and total lung
Others- consolidation, thoracic cage restriction, lung tissue restrictive disease will reduce lung volume
Pleural effusion, pneumothorax and abdominal distension compress the lung

Q

What does loss of lung volume mean to a physio?

A

A decrease amount of aerated lung, it can only be used to directly manage some causes of reduced lung volume, only collapse can be directly treated by physio techniques. When lung volume is not amenable to physio, v/q matching can be optimised.

Q

16
Q

How does IPPB ( the bird) work?

A

Intermittent positive pressure applied during inspiration, this pushes the patient into IRV. ( extra volume of air that can be inspired with maximal effort after reaching the end of a normal, quiet inspiration) Greater volumes means improved gas exchange and decreased WOB. The patient triggers inspiration by taking a breath and then a sustained positive pressure is applied to the patients airway to a set pressure level. This is followed by a passive expiration and is therefore a pressure supported inspiration.

17
Q

What are the indications for using IPPB or the Bird?

A

Atelectasis/ volume loss when the patient is tired, drowsy, weak or neurologically impaired. - unable to participate in more active treatments
May be used to aid secretion clearance

18
Q

What are the contraindications for using IPPB?

A 
Untrained pneumothorax 
Bronchospasm
Recent lung surgery
Hypoxic drive patients
Nausea
Flail chest
Haemoptysis
Bronchospasm
19
Q

What is the NIPPY clear way?

A

Airway assisting device with two settings
Mechanical insufflation- exsufflariom machine
Insufflation- positive inspiratory pressure - pushes air in
Exsufflation- negative pressure applied at the mouth for secretion removal - sucks air out
For volume loss just set the insufflation to a desired pressure
Nippy clear way can be put on a cough assist mode as well

20
Q

What can the NIPPY clear way be used for?

A

Due to its many modes the machine can be used to increase volumes, remove secretions and as a non invasive ventilator p

21
Q

What does CPAP stand for?

A

Continuous Positive Airway pressure

22
Q

What does CPAP involve?

A

It consists of positive pressure applied throughout the whole respiratory cycle ie inspiration and expiration.
It keeps the airway pressure higher than atmospheric throughout the whole respiratory cycle. It delivers a constant flow of gas which exceeds the patients demands.
This will increase FRC above CV thus recruiting collapsed alveoli and maintaining higher lung volumes

23
Q

What is the percussion technique?

A

It is also referred to as cupping or clapping. The purpose of percussion is to intermittently apply kinetic energy to the chest wall and lungs. This is accomplished by rhythmically striking the thorax with a cupped hand (for more air) over the lung segment being drained

24
Q

Resevoir

A

Normal o2 therapy plus the expired o2, the co2 is disposed off

25
Q

What is the 3 important components of the bird that the physio can manipulate?

A

How fast the breath goes in
The pressure at which the breath goes in
Starting effort or sensitivity

26
Q

What are the effects of a general anaesthetic in terms of treatments post op on the respiratory system?

A

Decreased mucocilliary clearance
Harder to inflate lungs
Less incentive to breath
Patient is drowsy and finds clearance more difficult
Sputum is drier and less mobile and hydrated so doesn’t move as well
FRC is lowered which affects closing volumes and decreases lung compliance and can cause atelectasis

27
Q

What is the different types of collateral channels for collateral ventilation

A

The ones between bronchioles called inter bronchial channels of Martin
The ones between bronchioles and alveoli - lambert
The ones between alveoli and alveoli- kohn

28
Q

What is incentive spirometry?

A

Patient is in relaxed sitting of side laying if extra volume is required in one lung due to v/q matching
Patient- tight seal around mouth piece and inhales deeply and slowly as they watch the mouth piece
If possible they create an end inspiratory hold- 3-4 seconds

Contraindications
People with severe dyspnoea
Fatigue
If they can’t use it properly

Indications for use- 
Presence of atelectasis 
Abdominal thoracic surgery
Prolonged bed rest
Surgery in patients with COPD 
Lack of pain control
Restricted lung diseases

It is used to facilitate sustained slow breathes

29
Q

How to measure the size of a catheter

A

Measure the size of the endotracheal tube and minus 2 and multiply by 2 and can add one if they have thick secretions

30
Q

What is the NIPPY clear way technique (cough assist)

A

It is a mechanical insufflation exsufflation
It can be used with different interfaces- mouth pie, face mask or tracheostomy connector
Insufflation- the inspiratory pressure
Exsufflation- the pressure applied at the mouth for secretion removal
It can set the pressures and
For volume loss just set the insufflation to the correct pressure

31
Q

What is bagging

A

Provides deep breaths in order to do increase lung volumes
Opens airways if atelectasis occurs
Facilitates secretion removal
Aids secretion removal as sputum clearance occurs during icu

32
Q

What are respiratory Adjuncts?

A

Apply the pressure at the mouth and breath out against resistance. They can be use in conjunction with other interventions. They help to remove secretions by increasing functional residual capacity and enhancing collateral ventilation for removing secretions from collapsed airways as they get air behind the secretions.
Eg flutter, acapella, bubble pep, pep mask

33
Q

What happens during bubble pep

A

Facilitates positive expiratory pressure which allows the patient to breath against resistance- facilitates collateral channels of ventilation

34
Q

What is the difference between restrictive and obstructive

A

Restrictive- can’t get air in

Obstructive- can’t get air out

35
Q

What is inspiratory reserve volume

A

The extra volume of air that can be inspired with maximal effort after reaching the end of a normal inspiratory volume

36
Q

If they are in respiratory acidosis or alkalosis

A

Alkalosis- getting rid of too much co2

Acidosis- retaining too much co2

37
Q

What does acapella do

A

Gives positive expiratory pressure, gives oscillations, helps splint the airways open, helps collateral ventilation, the oscillations also help to decrease the viscosity of the sputum

Acapella - prescription - puts pressure on the NHS
Flutter- patients have to buy their own- more cost effective

Don’t use adjuncts if they have had a previous tracheostomy
