Ventilation vs RespirationVentilation vs Respiration First: Get the terms straight. What most First: Get the terms straight. What most
people call people call respirationsrespirations are actually are actually ventilationsventilations
VentilationVentilation = Movement of air in and out = Movement of air in and out RespirationRespiration = Exchange = Exchange of oxygen and carbon of oxygen and carbon dioxide (in the lung or dioxide (in the lung or at the cell level)at the cell level)

Ventilation As ventilation begins the spaces between
the ribs expand and the diaphragm drops resulting in a vacuum in the chest.
Air rushes in from the atmosphere to fill the space.

REMEMBER!!! Must be able to breathe
spontaneously Must have good rise and fall of the
chest

Management 2: Ventilation Support
Use Bag-Valve-Mask ventilation if patient shows signs of fatigue • Slowing ventilations• Poor rise and fall of the chest• Altered level of consciousness with poor
ventilation • Use supplemental oxygen
![Page 63: Presence Regional EMS System](https://reader037.vdocument.in/reader037/viewer/2022103106/5a4d1aca7f8b9ab05996f50b/html5/thumbnails/63.jpg)
Management 3: CPAP: Continuous Positive Airway Pressure
A means of providing high flow, low pressure oxygenation to the patient in severe respiratory distress or respiratory failure
Goals of CPAP
• Increase the amount of inspiredIncrease the amount of inspiredoxygenoxygen• Decrease the work of breathingDecrease the work of breathing
![Page 64: Presence Regional EMS System](https://reader037.vdocument.in/reader037/viewer/2022103106/5a4d1aca7f8b9ab05996f50b/html5/thumbnails/64.jpg)
CPAP Increases the airway pressures allowing for better
gas diffusion & for re-expansion of collapsed alveoli
Allows the refilling of collapsed, airless alveoli Expands the surface area of the collapsed alveoli
allowing more surface area to be in contact with capillaries for gas exchange
Without CPAP With CPAP
![Page 65: Presence Regional EMS System](https://reader037.vdocument.in/reader037/viewer/2022103106/5a4d1aca7f8b9ab05996f50b/html5/thumbnails/65.jpg)
CPAP CPAP is applied during the entire
respiratory cycle (inhalation & exhalation) via a tight fitting mask applied over the nose and mouth
The patient must be able to maintain an upright sitting position
![Page 66: Presence Regional EMS System](https://reader037.vdocument.in/reader037/viewer/2022103106/5a4d1aca7f8b9ab05996f50b/html5/thumbnails/66.jpg)
Indications for CPAP ApplicationIndications for CPAP Application
Patient has severe respiratory distress and/or respiratory failure
To ease significant labored respirations and work of breathing in patients on supplemental oxygen who may otherwise require intubation
Patient exhibiting hypoxemia (O² sat <94% at any time) not responsive to supplemental oxygen therapy
![Page 67: Presence Regional EMS System](https://reader037.vdocument.in/reader037/viewer/2022103106/5a4d1aca7f8b9ab05996f50b/html5/thumbnails/67.jpg)
Criteria for CPAP(all must apply) Age ≥ 14 Fully cooperative patient, exhibiting a
reliable respiratory rate and effort, and able to protect their airway.
Medical patient with SBP≥90 mmHg No presence of nausea or vomiting
![Page 68: Presence Regional EMS System](https://reader037.vdocument.in/reader037/viewer/2022103106/5a4d1aca7f8b9ab05996f50b/html5/thumbnails/68.jpg)
Patient Monitoring During CPAP Use
Patient tolerance; mental status Respiratory pattern
• rate, depth, subjective feeling of improvement
• B/P, pulse rate & quality, SaO2,EtCO2 EKG pattern
![Page 69: Presence Regional EMS System](https://reader037.vdocument.in/reader037/viewer/2022103106/5a4d1aca7f8b9ab05996f50b/html5/thumbnails/69.jpg)
Indications the patient is improving (can be noted in as little as 5 minutes after beginning)reduced effort & work of breathing increased ease in speakingslowing of respiratory and pulse rates increased SaO2

Discontinuation of CPAP Hemodynamic instability
• B/P drops below 90 mmHg The positive pressures exerted
during the use of CPAP can negatively affect the return of blood flow to the heart
Inability of the patient to tolerate the tight fitting mask
