Advanced Cardiovascular Support Pressure System Fundamentals

UNIT I

A. PRESSURE SYSTEM BASICS
1. Pulmonary ventilation

a) Definitions
i. Ventilation
Act to move or direct air movement for a given porposito.

ii.
Inspiration Movement for introducing air into the lungs.

iii. exhalation
phenomenon is the opposite of inspiration, which air dureante found in the lungs out of them. It is a passive phase of breathing, because the chest is retracted and reduce us all diameters, without the intervention of muscle contraction.

iv.
diaphragm muscle that separates the chest from the abdominal cavity.

v. Pressure Intratoraxica -

B. LUNG VOLUME

1. Definitions and Amounts
a) VT - Tidal volume
b) ERV - Volume exhalation Reserve
c) RV - Volume Reserve
d) TLC - Total Lung Capacity
e) IC -
f) FRC - Functional Residual Capacity
g) VC - Current Volume

C. POINTS TO REVIEW

1. Atelectasis - is caused by a blockage of the airways (bronchi
or bronchioles) or by pressure on the outside of the lung.

2. Hemothorax - is an accumulation of blood in the space between
the chest wall and the lungs (pleural cavity).

3. Barotrauma - In patients with mechanical ventilation, the presence of extra-alveolar air
in places where normalmenteno found.

4. pneumothorax -


Class Notes

Centers Respiratory

respiratory centers are located in the central nervous system level and the pons and medulla are that regular orders and regulate the inspiration and expiration (breathing cycle).

For breathing is adequate, not only have to be normally functioning respiratory centers, must be accompanied by a normal function of the skeleton at the spine and the muscles involved in breathing, which are convenient to remember:

Ü major inspiratory muscles

Ø Diaphragm

Ø intercostals External

Ø Sternocleidomastoid

ü most important expiratory muscles

Ø Abdominal

Ø Internal intercostals

Pulmonary Ventilation

The amount of air that enters or leaves the lungs each minute.

If we know the amount of air entering the lungs with each breath (this is called the tidal volume) and multiplied by respiratory rate, we in volume / minute [minute = tidal volume X RR].
