Airway and Ventilation
Mnemonics for oxygen therapy, respiratory failure and ventilatory support.
Entries in Airway and Ventilation
Gas is fully saturated at body temperature by the time it reaches the isothermic boundary
A memory aid for how inspired gas is conditioned.
Diffuse alveolar damage causes non-cardiogenic oedema, shunt and stiff lungs
A memory aid for the physiology of acute respiratory distress syndrome.
Reduced functional residual capacity, blunted drive, and atelectasis
A memory aid for the respiratory changes under general anaesthesia.
The diaphragm alone at rest, with accessory muscles for forced inspiration and abdominals for forced expiration
A memory aid for which muscles are used in quiet and forced breathing.
CPAP for oxygenation, BiPAP for ventilation
A memory aid for when to use CPAP and when to use BiPAP.
Target saturations of 94 to 98 per cent, or 88 to 92 per cent if at risk of hypercapnia
A memory aid for prescribing oxygen safely.
From nasal cannulae to non-rebreathe and Venturi masks
A memory aid for the oxygen delivery devices and the concentrations they give.
Variable devices depend on the patient's breathing pattern; fixed devices do not
A memory aid for fixed and variable performance oxygen devices.
It reverses the normal negative intrathoracic pressure, reducing venous return
A memory aid for the physiological consequences of positive pressure ventilation.
It makes ventilation more uniform while perfusion remains relatively unchanged
A memory aid for why proning improves oxygenation.
Type 1 is hypoxaemia alone; type 2 adds hypercapnia
A memory aid for distinguishing type 1 from type 2 respiratory failure.
Rate, accessory muscles, recession, position and the ability to speak
A memory aid for recognising increased work of breathing.
Sixteen to twenty C-shaped cartilages, open posteriorly and bridged by the trachealis muscle
A memory aid for the structure of the trachea and why its cartilages are incomplete.
Type 1 is a gas exchange problem, type 2 a ventilation problem
A memory aid for classifying respiratory failure and its causes.
Elastic work plus resistive work, minimised at an optimal respiratory rate
A memory aid for the components of the work of breathing.
