Ventilation

Question 1

If you’ve got volume loss what do you do

Answer 1

Positioning
ACBT
INCENTIVE SPIROMETER- 10 breaths per hour - this is if the patient can’t understand the instructions
Bird is used after this- 3 main instructions -volume, pressure and senstivity- start at 10 and adjust it for the patient
Nippy clear way- one that can used with cough assist as it can give a breath in and a breath out
CPAP- used for atelectasis/ collapse - splints airways open
Mechanical ventilation- should know what settings to put it on- intubation (tube down throat) (tracheostomy)- made in throat- better lung term because it is better for weaning the patient off as it can be unplugged and they can breath, tracheostomy can be permanent as well. Intubation scrapes along throat

Pressure controlled ventilation, volume controlled ventilation or combined ventilation -

In normal breathing, taking a breath in, the pressure inside the lungs is lower, the diaphragm contracts and moves down, chest wall moves out, (pump handle and bucket handle) this creates a lower pressure inside the lungs and all the structures relax to their original state which increase the pressure and pressure is lower outside the lungs so air moves back out.
(Pressure moves from high concentration to low concentration)

Question 2

What types of mechanical ventilation exist

Answer 2

Pressure controlled
Volume controlled
Spontaneous
SIMW- volume (synchronised intermittent mandatory ventilation which is volume control)

For a patient in ICU- PEEP prevents collapsing of the airways on expiration. If they need a PEEP of more than 15, you can’t disconnect the ventilator to use suction using the sterile glove technique.

Ventilator gives peep.
