Four bones of the skull contain paired air spaces called that help to lighten the heavy load of the head.
yanalaym [24]

Four bones of the skull contain paired air spaces called the paranasal sinuses that help to lighten the heavy load of the head.

<h3>What is Paranasal Sinus?</h3>

The paranasal sinuses are air-filled, bony spaces located next to the nasal passages in the face bones of the skull. They grow via slowly expanding pneumatized cells that erupt from the nasal cavity. The term is typically used in everyday speech to refer to the hollow, air-filled spaces in front of the human skull. There are four pairs of sinuses in humans. There are now eight sinuses in all. These four pairs of sinuses are together referred to as paranasal sinuses since they are all joined to the nasal cavity.

Therapeutic Hypothermia and Targeted Temperature Management for Traumatic Arrest and Surgical Patients
IceJOKER [234]

Prior studies have not included trauma and postoperative patients, but it has been demonstrated that therapeutic hypothermia (TH) and targeted temperature management (TTM) improve outcomes in cardiac arrest survivors. We investigated the safety of TH/TTM in surgical and trauma patients. An adult patient who presented with a cardiac or traumatic arrest in the postoperative period and had been treated with either TH or TTM had a Glasgow Coma Scale of 8 when the patient was reviewed in a retrospective cohort study at a single level I trauma center. A patient's neurological recovery is deemed positive if they were released after obeying orders.

32 cardiac arrest patients in all, 14 of whom received TH treatment and 18 of whom received TTM treatment, with target temperatures of 33°C and 36°C, respectively, were included in the study. With 26 (81%) men, the cohort had a mean age of 60 13. There were 14 postoperative patients and 18 trauma patients. Pneumonia (13%), sepsis (6%), bleeding that required transfusion (22%), arrhythmias (6%), and seizures (9%), which are similar to earlier reported series, were among the complications. All survivors had good neurological recovery, and the overall survival rate (n = 13) to discharge was 41%. Patients who had previously been excluded from TH/TTM studies due to traumatic arrest and postoperative cardiac arrest appear to have an acceptable incidence of problems compared to conventional TH/TTM patients.

What is cardiac arrest ?

When the heart unexpectedly and unexpectedly stops pumping, cardiac arrest happens. If this occurs, blood supply to the brain and other important organs is interrupted. Certain arrhythmias that stop the heart from pumping blood result in cardiac arrests. A medical emergency is cardiac arrest.

Andru [333]

Answer:

To a certain point

Explanation:

Welll for one the government has moved towards getting rid of fruit flavored vapes by banning them here in the US. As well as the government increasing the age to purchase nicotine products federally.  Now this is currently a small think but I think for the teens that are not truly addictied to nicotine this will stop them from using it. Though I think the truly addicted ones will continue no matter the taste. I mean an obvious action would be to ban them overall.
