Study Notes
Airway Management Concepts
- To minimize gastric distension during bag-valve mask ventilation, avoid increasing the tidal volume.
- Elevated carbon dioxide levels in the bloodstream indicate hypercarbia.
- Positive-pressure ventilation raises intrathoracic pressure, which can reduce cardiac output due to diminished venous return.
Airway Devices and Techniques
- Oropharyngeal airways are crucial for unconscious patients with poor respiration; they are typically necessary for patients like a 40-year-old unconscious individual with shallow breaths.
- In emergencies where an apneic patient regurgitates, it is important to roll them onto their side and remove the oral airway to prevent aspiration.
- For a patient in respiratory distress unable to follow commands, assistance with a bag-valve mask is recommended.
Respiratory Measurements
- Tidal volume refers to the volume of air exchanged during a single breath.
- A nasal cannula is suitable when a non-rebreather mask isn't tolerated by the patient.
Safety and Anatomy
- The pin-indexing system for gas cylinders ensures that the correct regulator is used to match the cylinder type.
- The cricoid cartilage is a significant anatomical feature forming the lower part of the larynx.
Patient Care Considerations
- In a case of foreign body airway obstruction where a patient is alert and coughing, the best approach is to encourage coughing and transport the patient.
- Using a nasopharyngeal airway on a trauma patient poses risks of penetrating the cranium.
- Oxygen toxicity occurs from excessive oxygen levels, leading to cellular damage.
- Gas exchange of oxygen and carbon dioxide takes place in the alveolar sacs.
Metabolism and Respiratory Functions
- Cells use aerobic metabolism to convert glucose into energy in the presence of oxygen.
- Deep respirations do not lead to decreased tidal volume; they actually enhance it.
- Continuous Positive Airway Pressure (CPAP) is effective for patients with pulmonary edema who can follow commands.
Clinical Indicators
- The jaw-thrust maneuver is particularly important for patients with suspected cervical spine injuries to maintain airway patency.
- Hypoxia is defined as insufficient oxygen reaching the tissues and organs.
- Normal respiratory rate for adults at rest falls between 12 and 20 breaths per minute.
