What is the purpose of using PEEP valves in paediatric patients?
To prevent alveoli collapse
What is the purpose of reopening alveoli during ventilation?
To prevent alveoli collapse
Which of the following is NOT a reason why airway management is important?
To prevent laryngospasm in cats
What is the purpose of using cuffed endotracheal tubes during airway management?
To reduce the likelihood of secretions passing down into the trachea
What is the purpose of using topical Lidocaine spray during airway management in cats?
To prevent laryngospasm
What is the main advantage of using an LMA (Laryngeal Mask Airway) for airway protection during short procedures?
It allows positive pressure ventilation
What is the recommended method for pre-oxygenation during anesthesia?
Using a cuffed endotracheal tube
What can happen if alveoli collapse between breaths?
Hypoxia
What are some reasons why airway management is important?
Airway management is important because it allows the delivery of oxygen and volatile anaesthetic agents to the patient, removes carbon dioxide, protects the airway from obstruction, and enables positive pressure ventilation if required.
What are some sources of oxygen in practice?
Some sources of oxygen in practice include cylinders (E or J size), oxygen concentrators with power supply, and liquid oxygen in large human hospitals.
What are some considerations when using endotracheal tubes?
When using endotracheal tubes, it is important to check them before use, inflate the cuff to 25mmHg using a manometer if possible, and consider using cuffed tubes to prevent secretions from coming up and going down the trachea.
What are some advantages of using PVC and silicone tubes for endotracheal intubation?
PVC and silicone tubes are less prone to cracking and kinking, non-irritant, allow visualization of blockages, and usually have a high volume low pressure cuff.
What are some advantages of using laryngeal mask airway (LMA) for airway protection during short procedures?
LMA is achieving popularity due to its effectiveness and patient comfort. It can be used to protect the airway similar to an endotracheal tube, allows for ventilation, and can be used for bronchoscopy.
What are some complications that can occur during airway management?
Complications include tracheal trauma, pressure necrosis, Macy tracheitis, subcutaneous emphysema, and obstruction. It is important to monitor the adequacy of ventilation using capnography and pulse oximetry.
What should you do after giving a breath to the animal?
Always open the valve.
Why should you avoid being over enthusiastic when ventilating an animal?
It can lead to trauma.
What is the purpose of using PEEP valves in paediatric patients?
To prevent alveoli collapse between breaths.
Which valve should be closed before squeezing the rebreathing bag?
The exploratory valve.
Which type of endotracheal tube is commonly used and prone to cracking and kinking over time?
Red rubber tube
What is the main advantage of using an LMA (Laryngeal Mask Airway) for airway protection during short procedures?
Channels to divert regurgitation can be incorporated
