Study Notes

Decompression Illness

  • Therapy for decompression illness caused by too fast decompression after exposure to increased pressure is hyperbaric oxygenation (HBO)
  • Gas bubbles in decompression illness can cause pulmonary embolism

Pulmonary Embolism

  • Recommended therapy for pulmonary embolism is hyperbaric oxygenation (HBO)

Mechanical Ventilation

  • Goal of mechanical ventilation is to provide a work of breathing for the patient
  • Mode of ventilation that depends on lung compliance is Pressure-Regulated Volume Control (PRVC)

History of Ventilation

  • According to John Hunter in the mid-18th century, the first method-of-choice after drowning was mouth-to-mouth respiration
  • In the early 1800s, the first device described as a negative-pressure ventilator was the "spirometer"
  • Drinker and Shaw modified the device in the 1920s, leading to the invention of the 'Iron Lung'

Non-Invasive Ventilation (NIV)

  • Mode most commonly used for prolonged weaning and spontaneous breathing trials is Pressure Support (PS)
  • SIMV in NIV stands for Synchronized Intermittent Mandatory Ventilation
  • Primary goal of Pressure-Regulated Volume Control (PRVC) in NIV is to provide a work of breathing for the patient
  • Mode that adjusts peak inspiratory pressure (PIP) constantly in relation to the goal tidal volume is Pressure-Regulated Volume Control (PRVC)
  • Mode associated with increasing residual volume and hyperventilation as potential complications is Volume-Control (VC)
  • Popular mode for Acute Respiratory Distress Syndrome (ARDS) is Pressure-Control (PC)
  • Mode that aims to provide a work of breathing for the patient is Pressure Support (PS)
  • Mode that utilizes varying pressures depending on pulmonary compliance and airway resistance is Pressure-Regulated Volume Control (PRVC)
  • Primary complication associated with Pressure Support (PS) mode is over-assistance
  • Mode characterized by breaths that are patient- or time-triggered and are pressure-targeted and time-cycled is Pressure-Control (PC)
  • Mode that adjusts peak inspiratory pressure (PIP) according to the goal tidal volume and is commonly used for Acute Respiratory Distress Syndrome (ARDS) is Pressure-Control (PC)
  • Mode that allows spontaneous breaths to be unsupported and slightly pressure-supported is Pressure Support (PS)
  • Main indication for using a nasal cannula for NIV is for patients with claustrophobia or facial trauma
  • Contraindication for NIV using a mask is facial trauma or severe maxillofacial disease
  • Indication for continuous positive airway pressure (CPAP) is for obstructive sleep apnea
  • Bi-level Positive Airway Pressure (BPAP) helps to reduce pressure during exhalation
  • Main indication for hyperbaric oxygenation (HBO) is for decompression illness
  • Oxygen Dissociation Curve illustrates the relationship between PaO2 and SaO2
  • If SaO2 is 97% and SvO2 is 65%, the Sa-vO2 value is 32%
  • Mode of NIV with a low risk of ventilation-related injuries or pneumonia is CPAP
  • Condition that would indicate the use of a nasal cannula is claustrophobia or facial trauma
  • Condition that indicates the use of Bi-level Positive Airway Pressure (BPAP) is chronic obstructive pulmonary disease (COPD)
  • Most common contraindication for NIV using a mask is facial trauma or severe maxillofacial disease
  • Continuous Positive Airway Pressure (CPAP) helps to open up atelectatic regions in the lungs
