Which Of The Following Is True Regarding Respiratory Anatomy In Infants And Children?

What is the best reason that the EMT should be knowledgeable about normal anatomy and physiology?

What is the BEST reason that the EMT should be knowledgeable about normal anatomy and​ physiology? It will help the EMT to recognize when​ life-threatening findings are present.

What occurs during normal and Unlabored exhalation?

During expiration, the inspiratory muscles relax causing the volume of the thoracic cavity to be reduced. The relaxation of the diaphragm increases intrapleural and intrapulmonary pressures forcing the gases in the lungs out. Normally, unlabored expiration at rest is passive by relaxation of inspiratory muscles.

Why is it critical to manage swelling of the pediatric patient’s airway?

Why is it critical to manage swelling of the pediatric patient’s airway? Because of the small diameter of the pediatric airway.

When stimulated the alpha receptors of the sympathetic nervous system result in which of the following effects?

The types of sympathetic or adrenergic receptors are alpha, beta-1 and beta-2. Alpha – receptors are located on the arteries. When the alpha receptor is stimulated by epinephrine or norepinephrine, the arteries constrict. This increases the blood pressure and the blood flow returning to the heart.

Why is anatomy so important?

Knowledge of anatomical structure of the body is basic to understanding musculoskeletal function and how both structure and function are modified by exercise or disease. This is true for professionals in physical therapy and athletic training and it is true for exercise physiologists too.

What are the minimum infection control precautions?

Standard Precautions

  • Hand hygiene.
  • Use of personal protective equipment (e.g., gloves, masks, eyewear).
  • Respiratory hygiene / cough etiquette.
  • Sharps safety (engineering and work practice controls ).
  • Safe injection practices (i.e., aseptic technique for parenteral medications).
  • Sterile instruments and devices.

What is the breathing process?

The process of breathing, or respiration, is divided into two distinct phases. The first phase is called inspiration, or inhaling. When the lungs inhale, the diaphragm contracts and pulls downward. At the same time, the muscles between the ribs contract and pull upward.

What is the normal drive to breathe?

Normal respiration is driven mostly by the levels of carbon dioxide in the blood, which are detected by central chemoreceptors, via a change in pH. It has very little by the oxygen levels. An increase in carbon dioxide will cause chemoreceptor reflexes to trigger an increase in respirations.

What are the two phases of respiration?

Breathing (or pulmonary ventilation) has two phases – inspiration (or inhalation) and expiration (or exhalation). It is a mechanical process that depends on volume changes in the chest cavity.

How do I manage my baby’s airways?

Positioning Infants and Young Children for Airway Management Simple extension of the neck can bring an infant into optimal sniffing position. More often than not, a combination of a shoulder roll and head rest is required as shown in the graphics below.

How do you assess an airway in children?

Endoscopy. Endoscopy of the pediatric airway involves the use of either fibreoptic or rigid instruments. Flexible pernasal laryngoscopy is possible even in neonates, using a small-caliber fibroscope. It can be performed without general anesthesia, with the application of local anesthesia to the nasal fosse.

How do you open a pediatric airway?

Instead, you should place a small rolled towel under the shoulders in children younger than 2 years to open the airway (Figure 8A). As the child reaches 2 years of age, the occiput gradually becomes less prominent but is still rounded. Keeping the head in a more neutral position is helpful at this age.

What’s the difference between alpha and beta receptors?

The difference between Alpha Receptors and Beta Receptors is that the Alpha receptors are involved in the contraction of blood vessels and in the stimulation of effectors cells. Beta Receptors on the other hand are involved in the dilatation of blood vessels and relaxation of effectors cells.

What is the action and side effects of alpha and beta receptor antagonists?

Alpha – blockers work on norepinephrine or noradrenaline, while beta – blockers work on epinephrine or adrenaline. Alpha – blockers affect only blood pressure levels, while beta – blockers affect both the heart and blood pressure. Beta – blockers can cause weight gain, while alpha – blockers do not.

What do the alpha receptors do?

Alpha receptors are known to function for vasoconstriction, iris dilation, intestinal relaxation, intestinal sphincter contraction, pilomotor contraction, and bladder sphincter contraction.
