Answer:
This is achieved because the sodium channels have a refractory period following activation, during which they cannot open again. This ensures that the action potential is propagated in a specific direction along the axon.
An unconscious adult victim is gasping for breath and having difficulty breathing. The scene is safe and help has been called. Next you should use the head tilt chin lift procedure.
An unconscious patient is at risk of blocking their airway and suffocating. The main reason for this occurring is due to the tongue. An unconscious patient loses all their muscular tone, and this includes the tongue! The tongue can fall back and block the airway.
This situation is an emergency – without a supply of oxygen reaching the lungs, the patient will suffocate in a matter of minutes.
In CPR, we use the head-tilt, chin-lift method to open the airway.
How to Perform a Head-tilt Chin-lift :
- Kneel next to the patient’s head
- Place one hand on the patient’s forehead and tilt the head gently backward
- Place two fingers under the bony part of their chin and lift the chin vertically upwards
- Take care not to place any pressure on the soft part of the neck as this could obstruct the airway
If a cervical spine injury is suspected, then the modified jaw thrust would be used in place of "head-tilt, chin-lift". The jaw thrust is a technique used on patients with a suspected spinal injury and is used on a supine patient.

<h3>
What is a consent?</h3>
Consent is the voluntary acceptance of another person's offer or wish. It has specific definitions as used in the legal system, medical field, scientific community, and sexual relationships. Consent may not mean what is commonly believed when used in a particular circumstance. For instance, a person with a mental illness, someone with a limited mental capacity, or someone who isn't of legal sexual consent age could voluntarily engage in a sexual act that doesn't satisfy the legal requirements for consent as specified by the relevant law.
The United Nations believes that it is advantageous to include the subject of consent in a comprehensive sexuality education program.
