This line of fusion divides inferiorly to enclose a triangular area called the mental protuberance. On each side, inferior to the second premolar tooth, is the mental foramen for the passage of blood vessels and a nerve. Melasma

The nose may be best known for inhaling oxygen and exhaling carbon dioxide, but it also contributes to other important functions, such as tasting. The anatomy of the nose can be divided into the external nose and the nasal cavity. Nose Anatomy (External & Internal).
  • Place your mouth fully over theirs. 
  • Blow hard enough to get chest rise (retilt head if chest does not rise).

Rescue breaths should be provided to apneic patients during CPR. Chest compressions should take precedence, especially in children, over rescue breaths.

Heimlich maneuver Heimlich maneuver An emergency treatment commonly used to clear food and other foreign objects causing airway obstruction. Foreign Body Aspiration

If patient’s chest does not rise, foreign object may be obstructing airway Airway ABCDE Assessment:

  • With patient supine → open airway Airway ABCDE Assessment using jaw Jaw The jaw is made up of the mandible, which comprises the lower jaw, and the maxilla, which comprises the upper jaw. The mandible articulates with the temporal bone via the temporomandibular joint (TMJ). The 4 muscles of mastication produce the movements of the TMJ to ensure the efficient chewing of food. Jaw and Temporomandibular Joint: Anatomy lift →  if foreign body Foreign Body Foreign Body Aspiration is visible, remove object with finger sweep (do not perform blind finger sweep).
  • Attempt rescue breaths → if unsuccessful, retilt head and reattempt rescue breaths.
  • If no chest rise → kneel next to or straddle hips of patient → use 2 hands on top of each other and place heel of bottom hand Hand The hand constitutes the distal part of the upper limb and provides the fine, precise movements needed in activities of daily living. It consists of 5 metacarpal bones and 14 phalanges, as well as numerous muscles innervated by the median and ulnar nerves. Hand: Anatomy below xiphoid process Xiphoid process Chest Wall: Anatomy → press both hands into abdomen with quick upward thrust 5 times.

Heimlich maneuver

Heimlich maneuver
In a choking patient or an unconscious patient on whom rescue breaths are not providing adequate ventilation, airway obstruction with a foreign object should be considered. The Heimlich maneuver works by producing positive pressure in the lungs, forcefully expelling any foreign body in the upper airway.

Chest Compressions

Positioning

  • Patient must be supine.
  • Patient must be lying on a firm surface.

Technique

  • In adults, use 2-hand chest compression Chest Compression Crush Syndrome technique:
    • 1 hand Hand The hand constitutes the distal part of the upper limb and provides the fine, precise movements needed in activities of daily living. It consists of 5 metacarpal bones and 14 phalanges, as well as numerous muscles innervated by the median and ulnar nerves. Hand: Anatomy on top of the other

It consists of 5 metacarpal bones and 14 phalanges, as well as numerous muscles innervated by the median and ulnar nerves. Hand: Anatomy over lower portion of the sternum Sternum A long, narrow, and flat bone commonly known as breastbone occurring in the midsection of the anterior thoracic segment or chest region, which stabilizes the rib cage and serves as the point of origin for several muscles that move the arms, head, and neck. Chest Wall: Anatomy, slightly below nipples.
  • Push “hard and fast”:
    • Appropriate rate: 100–120 compressions/min
    • Adequate depth: 5.0–7.6 cm (2–3 in)

The two major components of cardiopulmonary resuscitation are artificial ventilation and closed-chest cardiac massage. Cardiac Arrest

  • Pause only to give rescue breaths.
  • If possible, have other providers prepare to take turns performing compressions (change every 2 minutes).
  • Avoid hyperventilation Hyperventilation A pulmonary ventilation rate faster than is metabolically necessary for the exchange of gases. It is the result of an increased frequency of breathing, an increased tidal volume, or a combination of both. It causes an excess intake of oxygen and the blowing off of carbon dioxide. Respiratory Alkalosis: ventilation Ventilation The total volume of gas inspired or expired per unit of time, usually measured in liters per minute. Ventilation: Mechanics of Breathing rate around 6/min

Defibrillation

Early defibrillation Defibrillation Ventricular Fibrillation (V-fib) has been shown to significantly improve morbidity Morbidity The proportion of patients with a particular disease during a given year per given unit of population. Measures of Health Status and mortality Mortality All deaths reported in a given population. Measures of Health Status in ventricular fibrillation Ventricular fibrillation Ventricular fibrillation (VF or V-fib) is a type of ventricular tachyarrhythmia (> 300/min) often preceded by ventricular tachycardia. In this arrhythmia, the ventricle beats rapidly and sporadically. The ventricular contraction is uncoordinated, leading to a decrease in cardiac output and immediate hemodynamic collapse. Ventricular Fibrillation (V-fib) ( VF VF Ventricular fibrillation (VF or V-fib) is a type of ventricular tachyarrhythmia (> 300/min) often preceded by ventricular tachycardia. In this arrhythmia, the ventricle beats rapidly and sporadically. The ventricular contraction is uncoordinated, leading to a decrease in cardiac output and immediate hemodynamic collapse. Ventricular Fibrillation (V-fib))/ventricular tachycardia Tachycardia Abnormally rapid heartbeat, usually with a heart rate above 100 beats per minute for adults. Tachycardia accompanied by disturbance in the cardiac depolarization (cardiac arrhythmia) is called tachyarrhythmia. Sepsis in Children ( VT VT Ventricular tachycardia is any heart rhythm faster than 100 beats/min, with 3 or more irregular beats in a row, arising distal to the bundle of his. Ventricular tachycardia is the most common form of wide-complex tachycardia, and it is associated with a high mortality rate. Ventricular Tachycardia) cardiac arrest Cardiac arrest Cardiac arrest is the sudden, complete cessation of cardiac output with hemodynamic collapse.

Timing

  • Chest compressions should be initiated before placing defibrillator Defibrillator Cardiac electrical stimulators that apply brief high-voltage electroshocks to the heart. These stimulators are used to restore normal rhythm and contractile function in hearts of patients who are experiencing ventricular fibrillation or ventricular tachycardia that is not accompanied by a palpable pulse. Some defibrillators may also be used to correct certain noncritical dysrhythmias (called synchronized defibrillation or cardioversion), using relatively low-level discharges synchronized to the patient’s ECG waveform. Cardiac Arrest.
  • Rhythm analysis/ shock Shock Shock is a life-threatening condition associated with impaired circulation that results in tissue hypoxia. The different types of shock are based on the underlying cause: distributive (↑ cardiac output (CO), ↓ systemic vascular resistance (SVR)), cardiogenic (↓ CO, ↑ SVR), hypovolemic (↓ CO, ↑ SVR), obstructive (↓ CO), and mixed. Types of Shock should be performed as soon as possible without interrupting high-quality chest compression Chest Compression Crush Syndrome.
  • Ideal timing is to pause between switching providers; done every 2 minutes.

Advance directives represent the ethical principle of autonomy and may take the form of a living will, health care proxy, durable power of attorney for health care (DPAHC), and/or a physician’s order for life-sustaining treatment (POLST).
