Final answer:
following statements are advantages of using a pocket mask b) I, II, IV
I- Has a one-way valve
II- Allows the use of supplemental oxygen
IV- Provides a barrier between the patient and the paramedic
Step-by-step explanation:
A pocket mask is advantageous for several reasons. It has a one-way valve (I) that allows for the delivery of rescue breaths to a patient while preventing the backflow of air or contaminants.
The pocket mask also allows the use of supplemental oxygen (II), which can be crucial in providing oxygen to a patient with compromised breathing. Additionally, it provides a barrier between the patient and the paramedic (IV), reducing the risk of cross-contamination during resuscitation efforts. Therefore, the correct answer is b) I, II, IV.
The one-way valve in the pocket mask ensures that the air delivered during rescue breaths goes into the patient's lungs and not back into the mask, preventing the potential transmission of infectious agents.
The ability to use supplemental oxygen (II) enhances the effectiveness of respiratory support, especially in cases where the patient requires higher concentrations of oxygen. The barrier provided by the pocket mask (IV) is an essential safety feature, protecting both the patient and the paramedic from exposure to bodily fluids and pathogens.
Understanding the features and advantages of a pocket mask is crucial for emergency medical professionals. These devices play a vital role in cardiopulmonary resuscitation (CPR) and first aid scenarios, providing a means to deliver effective rescue breaths while maintaining a safe and hygienic environment for both the rescuer and the patient.
