Different Body Systems

Cellular Metabolism

Cellular metabolism refers to the chemical reactions occurring within cells to maintain life. It can be divided into two main categories:

Catabolism: The breakdown of molecules to obtain energy. For example, glucose is broken down during cellular respiration to produce ATP.
Anabolism: The synthesis of all compounds needed by the cells. This includes the formation of proteins, nucleic acids, and lipids.

Overall, cellular metabolism is essential for energy production, growth, and maintenance of cellular function

- Begin at the lowest setting and titrate
- >12 years old

  - Pulmonary edema
  - COPD
  - Asthma
  - Pneumonia
- Caution with patients with hypotension and hypertension
- BiPAP = ICU
- Over ventilation = cardiac arrest

Notes on ventilation

Without an adequate airway, oxygenation, or ventilation, all other emergency care provided to a patient will be futile.
The most basic care for all patients focuses on establishing and maintaining a patent airway and providing adequate ventilation and oxygenation.
Assessment of the airway, oxygenation, and ventilation status occurs early in your patient contact.
For example, a patient can have an open airway but ineffective ventilation or adequate ventilation but ineffective oxygenation.
Thus, it is imperative to become highly efficient in assessing all three components and remain vigilant of any changes in their status.
An obstructed airway is opened using either the head-tilt, chin-lift maneuver or the jaw-thrust maneuver.
The head-tilt, chin-lift maneuver is performed on patients who do not have any suspected spinal injury, whereas the jaw-thrust maneuver is used to open the airway in a patient who has a suspected spinal injury while maintaining spine motion restriction.
The oropharyngeal airway can be inserted only in patients who have no gag reflex.
The nasopharyngeal airway can be used in patients who still have a slight gag reflex.
After the airway is established, the ventilation status is assessed.
When assessing and managing the airway, ventilation, and oxygenation, you must also be aware of special circumstances or patient conditions that can provide challenges, such as a patient with a stoma or tracheostomy tube, infants and children, facial injuries, foreign body obstruction, and dental appliances.

Intubation: Intubation is a medical procedure that involves placing a tube into a patient's airway to maintain an open airway and ensure adequate ventilation. It is commonly used in emergency situations, during surgeries, or in critically ill patients who are unable to breathe adequately on their own.

Types of Intubation

Endotracheal Intubation: Inserting a tube into the trachea to maintain an open airway.
Orotracheal Intubation: A specific technique of endotracheal intubation where the tube is inserted through the mouth.
Nasotracheal Intubation: Inserting the tube through the nose into the trachea; often used in conscious patients or to avoid mouth injuries.
Tracheostomy: A surgical procedure creating an opening in the neck into the trachea for long-term airway access.
Rapid Sequence Intubation (RSI): A technique used to quickly induce anesthesia and intubate, typically in emergency

Effective emergency care necessitates an adequate airway, ventilation, and oxygenation. Early assessment of these components is crucial. A patient can have an open airway without effective ventilation or vice versa. Airway obstruction relief can be achieved through the head-tilt, chin-lift maneuver (no spinal injury suspected) or jaw-thrust maneuver (if spinal injury is suspected). Oropharyngeal airways are for patients without a gag reflex, while nasopharyngeal airways can be used for those with a slight gag reflex. After establishing the airway, ventilation status is evaluated, considering special patient situations such as stomas, pediatrics, facial injuries, and obstructions.
