Respiratory arrest can be used interchangeably with complete respiratory failure. The former refers to the complete cessation of breathing, while respiratory failure is the inability to provide adequate ventilation for the body's requirements. However, both lead to death without intervention. Respiratory arrest is also different from cardiac arrest, the failure of heart muscle contraction. If untreated, one may lead to the other. The laryngeal mask airway is a tube with an inflatable cuff. A laryngeal mask airway can be positioned in the lower oropharynx to prevent airway obstruction by soft tissues and to create a safe channel for ventilation. The laryngeal mask airway is the standard rescue ventilation when endotracheal intubation cannot be accomplished. To insert the laryngeal mask airway into the patient, the deflated mask should be pressed against the hard palate, rotated past the base of the tongue, and reaching the pharynx. Once the mask has been placed in the correct position, the mask can be inflated. Some benefits of the laryngeal mask airway include minimization of gastric inflation and protection against regurgitation. A potential problem the laryngeal mask airway poses is that over inflation will make the mask more rigid and less able to adapt to the patient's anatomy, compressing the tongue and causing tongue edema. In that case, the mask pressure should be lowered or a larger mask size should be used. If noncomatose patients are given muscle relaxants before the insertion of the laryngeal mask airway, they may gag and aspirate when the drugs are worn off. At that point, the laryngeal mask airway should be removed immediately to eliminate the gag response and buy time to start at new alternative intubation technique. Decreased respiratory effort: Central nervous system impairment leads to decreased respiratory effort. Central nervous system disorders, such as stroke and tumors, may cause hypoventilation. Drugs may decrease respiratory effort as well, such as opioids, sedative-hypnotics, and alcohol. An overdose of any of these drugs may lead to a decreased respiratory effort. Metabolic disorders could also decrease respiratory effort. Hypoglycemia and hypotension depress the central nervous system and compromise the respiratory system. [2]. Diagnosis requires clinical evaluation. If there was a foreign body obstructing the airway, the first option would be to locate the foreign body. The presence of a foreign body can be detected from resistance to ventilation from the mouth-to-mask or bag-valvemask ventilation. The foreign body can be extracted during laryngoscopy for endotracheal intubation. [7]. Treatment involves clearing the airway, establishing an alternate airway, and providing artificial ventilation that can include modes of mechanical ventilation. There are many ways to provide an airway and to deliver breathing support. The list below includes several options. One common symptom of respiratory arrest is cyanosis, a bluish discoloration of the skin resulting from an inadequate amount of oxygen in the blood. If respiratory arrest remains without any treatment, cardiac arrest will occur within minutes of hypoxemia, hypercapnia or both. At this point, patients will be unconscious or about to become unconscious. [4]. Resistance to bag valve mask may suggest presence of a foreign body that is obstructing airways and commonly used as a diagnostic tool and treatment for respiratory arrest. The bag-valve-mask device has a self-inflating bag with a soft mask that rests on the face. When the bag is connected to an oxygen supply, the patient will receive 60 to 100% of inspired oxygen. The purpose of bag-valve-mask is to provide adequate temporary ventilation and allow the body to achieve airway control by itself. However, if the bag-valve-mask is left on for more than five minutes, air may be introduced into the stomach. At that point, a nasogastric tube should be inserted to take the accumulated air out. During this process, practitioners must carefully position and maneuver the bag-valve-mask in order to keep airways open. An oropharyngeal airway is used during bag-valve-mask ventilation to prevent oropharynx soft tissues

from blocking the airway. An oropharyngeal airway may cause gagging and vomiting. Therefore, an oropharyngeal airway must be sized appropriately. It should be as long as distance between corner of patient's mouth and angle of the jaw is calculated correctly. For TEENren, pediatric bags can be used. Pediatric bags have a valve that limits peak airway pressures to around 35 40 cm of water. Practitioners must tweak valve settings to accurately determine each of their patients to avoid hypoventilation or hyperventilation. [9]. The first step to diagnosing patient is to clear and open the upper airway with correct head and neck positioning to determine the cause of respiratory arrest. The practitioner must lengthen and elevate the patient's neck until the external auditory meatus is in the same plane as the sternum. The face should be facing the ceiling. The mandible should be positioned upwards by lifting the lower jaw and pushing the mandible upward. If a foreign body can be detected, the practitioner may remove it with a finger sweep of the oropharynx and suction. It is important that the practitioner does not cause the foreign body to be lodged even deeper into the patient's body. Foreign bodies that are deeper into the patient's body can be removed with Magill forceps or by suction. A Heimlick maneuver can also be used to dislodge the foreign body. The Heimlick maneuver consists of manual thrusts to the upper abdomen until the airway is clear. In conscious adults, the practitioner will stand behind the patient with arms around the patient's midsection. One fist will be in a clenched formation while the other hand grabs the fist. Together, both hands will thrust inward and upward by pulling up with both arms. [8]. Airway obstruction: Obstruction may occur in the upper and lower airway. Upper airway obstruction is common in infants less than 3 months old, because they are nose breathers. Nasal blockage may easily lead to upper airway obstruction in infants. For other ages, upper airway obstruction may occur from edema of the vocal cords, foreign bodies, or pharyngolaryngeal tracheal inflammation. Lower airway obstruction may occur from bronchospasm, drowning, or airspace filling disorders (e.g. pneumonia, pulmonary edema, pulmonary hemorrhage). [1]. Respiratory arrest is caused by apnea (cessation of breathing ) or respiratory dysfunction severe enough it will not sustain the body (such as agonal breathing ). Prolonged apnea refers to a patient who has stopped breathing for a long period of time. If the heart muscle contraction is intact, the condition is known as respiratory arrest. An abrupt stop of pulmonary gas exchange lasting for more than five minutes may damage vital organs especially the brain, possibly permanently. Lack of oxygen to the brain causes loss of consciousness. Brain injury is likely if respiratory arrest goes untreated for more than three minutes, and death is almost certain if more than five minutes. Respiratory muscle weakness: Neuromuscular disorders may lead to respiratory muscle weakness, such as spinal cord injury, neuromuscular diseases, and neuromuscular blocking drugs. Respiratory muscle fatigue can also lead to respiratory muscle weakness if patients breathe over 70% of their maximum voluntary ventilation. Breathing over an extended period of time near maximum capacity can cause metabolic acidosis or hypoxemia, ultimately leading to respiratory muscle weakness. [3]. A tracheal tube is inserted into the trachea through the mouth or nose. Endotracheal tubes contain high-volume, lowpressure balloon cuffs to minimize air leakage and the risk of aspiration. Cuffed tubes were made originally for adults and TEENren over 8 years old, but cuffed tubes have been used in infants and younger TEENren to prevent air leakage. Cuffed tubes can be inflated to the extent needed to prevent air leakage. The endotracheal tube is a guaranteed mechanism to secure a compromised airway, limit aspiration, and bring about mechanical ventilation in comatose patients. The endotracheal tube is a great method for patients who are comatose, have an obstructed airway, or need mechanical ventilation. The endotracheal tube also allows suctioning of the lower respiratory tract. Drugs that can be inserted through the endotracheal tube during cardiac arrest are discouraged. Before intubation, patients need correct patient positioning and ventilation with 100% oxygen. The purpose of

ventilation with 100% oxygen is to denitrogenate healthy patients and prolong the safe apneic time. Tubes with an internal diameter of over 8mm are acceptable for most adults. Insertion technique includes visualizing the epiglottis, the posterior laryngeal structure, and not passing the tube unless tracheal insertion is ensured. [10]. Surgical entry is required when the upper airway is obstructed by a foreign body, massive trauma has occurred, or if ventilation cannot be accomplished by any of the aforementioned methods. The requirement of the surgical airway is commonly known as the response to failed intubation. In comparison, surgical airways require 100 seconds to complete from incision to ventilation compared to laryngeal mask airways and other devices. During emergency cricothyrotomy, the patient lies on his back with neck extended and shoulders backward. The larynx is held in one hand by the practitioner while the other hand is holding a blade to incise the skin through the subcutaneous tissue and into the midline of the cricothyroid membrane to access the trachea. A hollow tube is used inserted into the trachea to keep the airway open. A tracheal hook is used to keep the space open and prevent retraction. Complications may include hemorrhage, subcutaneous emphysema, pneumomediastinum, and pneumothorax. Cricothyrotomy is used as emergency surgical access due to being fast and simple. Another surgical airway method is called tracheostomy. Tracheostomy is done in the operating room by a surgeon. This is the preferred method for patients requiring long-term ventilation. Tracheostomy uses skin puncture and dilators to insert the tracheostomy tube. [11]. A condition that frequently precedes respiratory arrest is respiratory distress, which is a gradual, subtle imbalance in patient response that can result in eventual respiratory failure and arrest. Symptoms of respiratory compromise can differ with each patient. Complications from respiratory compromise are increasing rapidly across the clinical spectrum, partly due to expanded use of opioids combined with the lack of standardized guidelines among medical specialties. While respiratory compromise creates problems that are often serious and potentially life-threatening, they are almost always preventable with the proper tools and approach. Appropriate patient monitoring and therapeutic strategies are necessary for early recognition, intervention and treatment. [5]. Patients with respiratory arrest can be intubated without drugs. However, patients can be given sedating and paralytic drugs to minimize discomfort and help out with intubation. Pretreatment includes 100% oxygen, lidocaine, and atropine. 100% oxygen should be administered for 3 to 5 minutes. The time depends on pulse rate, pulmonary function, RBC count, and other metabolic factors. Lidocaine can be given in 1.5 mg/kg IV a few minutes before sedation and paralysis. The purpose of administering lidocaine is to blunt the sympathetic response of an increased heart rate, blood pressure, and intracranial pressure caused by laryngoscopy. Atropine can be given when TEENren produce a vagal response, evidenced by bradycardia, in response to intubation. Some physicians even give out vecuronium, which is a neuromuscular blocker to prevent muscle fasciculations in patients over 4 years old. Fasciculations may result in muscle pain on awakening. Laryngoscopy and intubation are uncomfortable procedures, so etomidate may be delivered. Etomidate is a short-acting IV drug with sedative analgesic properties. The drug works well and does not cause cardiovascular depression. Ketamine is an anesthetic that may be used as well, but it may cause hallucinations or bizarre behavior upon awakening. Thiopental and methohexital may be used as well to provide sedation, but they tend to cause hypotension. [12]. of the respiratory system. The volume-cycled ventilation is the simplest and most efficient of providing ventilation to a patient's airway compared to other methods of mechanical ventilation. Each inspiratory effort that is beyond the set sensitivity threshold will be accounted for and fixed to the delivery of the corresponding tidal volume. If the patient does not breathe enough, then the volume-cycled ventilation will initiate a breath for the patient to bring up the breathing rate to the minimum respiratory rate. The synchronized intermittent mandatory

ventilation (SIMV) is a similar method of mechanical ventilation that also delivers breaths at a fixed rate and volume that corresponds to the patient's breathing. Unlike the Volume-Cycled Ventilation, patient efforts above the fixed rate are unassisted The purpose of mechanical ventilators is to deliver a constant volume, constant pressure, or a combination of both with each breath. Any given volume will correspond to a specific pressure on the pressure-volume curve and vice versa in any case. Settings on each mechanical ventilator may include respiratory rate, tidal volume, trigger sensitivity, flow rate, waveform, and inspiratory/expiratory ratio. The volumecycled ventilation includes the volume-control function and delivers a set tidal volume. The pressure is not a fixed number but it varies with resistance and capacitance. Abnormal speech (have the patient say "you can't teach an old dog new tricks"). Sodium nitroprusside 0.5 µg/kg per minute IV infusion as initial dose and titrate to desired blood pressure. Aim for a 10% to 15% reduction in blood pressure. The ACLS Suspected Stroke Algorithm emphasizes critical actions for out-of-hospital and in-hospital care and treatment. Labetalol 10 mg IV for 1 2 min may repeat or double every 10 min to maximum dose of 300 mg or give initial labetalol dose and then start labetalol drip at 2 to 8 mg/min OR nicardipine 5 mg/hr IV infusion as initial dose and titrate to desired effect by increasing 2.5 mg/hr every 5 min to maximum of 15 mg/hr; if blood pressure is not controlled by nicardipine, consider sodium nitroprusside. Assess the patient using the CPSS or the LAPSS. Neurologic assessment by stroke team and CT scan performed within 25 minutes of arrival. Observe patient unless there is other end-organ involvement. Treat the patient's other symptoms of stroke (headache, pain, nausea, etc). Treat other acute complications of stroke, including hypoxia, increased intracranial pressure, seizures, or hypoglycemia. Note that the patient is not a candidate for fibrinolytics. Figure 2. Management guidelines for elevated blood pressure in patients with acute ischemic stroke. The 2018 ACLS guidelines have been in effect since October 2015 when the American Heart Association released the most recent guidelines changes for BLS, ACLS, and PALS. Furthermore, these guidelines will be good through 2020 when the AHA meets again to update the guidelines. There were some minor changes to both the BLS and ACLS Guidelines. The guideline changes that occurred with the release of the 2015 ACLS & BLS Guidelines can be reviewed using the links below. The articles will provide a complete review of the guideline changes released by the American Heart Association in their Executive Summary: 2015 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care. Please feel free to ask a question in the comments section below if something is not clear. This 6 minute video covers all the 2015 guideline changes listed below. 2018 ACLS Guideline Changes Review. Labetalol 10 mg IV for 1 2 min may repeat or double every 10 to 20 min to a maximum dose of 300 mg or give initial labetalol dose, then start labetalol drip at 2 to 8 mg/min. New!

Some benefits of the laryngeal mask airway include minimization of gastric inflation and protection against regurgitation. A potential problem the laryngeal mask airway poses is that over inflation will make the mask more rigid and less able to adapt to the patient's anatomy, compressing the tongue and causing tongue edema. In that case, the mask pressure should be lowered or a larger mask size should be used. If noncomatose patients are given muscle relaxants before the insertion of the laryngeal mask airway, they may gag and aspirate when the drugs are worn off. At that point, the laryngeal mask airway should be removed immediately to eliminate the gag response and buy time to start at new alternative intubation technique. Respiratory arrest is caused by apnea (cessation of breathing ) or respiratory dysfunction severe enough it will not sustain the body (such as agonal breathing ). Prolonged apnea refers to a patient who has stopped breathing for a long period of time. If the heart muscle contraction is intact, the condition is known as respiratory arrest. An abrupt stop of pulmonary gas exchange lasting for more than five minutes may damage vital organs especially the brain, possibly permanently. Lack of oxygen to the brain causes loss of consciousness. Brain injury is likely if respiratory arrest goes untreated for more than three minutes, and death is almost certain if more than five minutes. Surgical entry is required when the

upper airway is obstructed by a foreign body, massive trauma has occurred, or if ventilation cannot be accomplished by any of the aforementioned methods. The requirement of the surgical airway is commonly known as the response to failed intubation. In comparison, surgical airways require 100 seconds to complete from incision to ventilation compared to laryngeal mask airways and other devices. During emergency cricothyrotomy, the patient lies on his back with neck extended and shoulders backward. The larynx is held in one hand by the practitioner while the other hand is holding a blade to incise the skin through the subcutaneous tissue and into the midline of the cricothyroid membrane to access the trachea. A hollow tube is used inserted into the trachea to keep the airway open. A tracheal hook is used to keep the space open and prevent retraction. Complications may include hemorrhage, subcutaneous emphysema, pneumomediastinum, and pneumothorax. Cricothyrotomy is used as emergency surgical access due to being fast and simple. Another surgical airway method is called tracheostomy. Tracheostomy is done in the operating room by a surgeon. This is the preferred method for patients requiring long-term ventilation. Tracheostomy uses skin puncture and dilators to insert the tracheostomy tube. [11]. This list is incomplete; you can help by expanding it. Decreased respiratory effort: Central nervous system impairment leads to decreased respiratory effort. Central nervous system disorders, such as stroke and tumors, may cause hypoventilation. Drugs may decrease respiratory effort as well, such as opioids, sedative-hypnotics, and alcohol. An overdose of any of these drugs may lead to a decreased respiratory effort. Metabolic disorders could also decrease respiratory effort. Hypoglycemia and hypotension depress the central nervous system and compromise the respiratory system. [2]. Treatment involves clearing the airway, establishing an alternate airway, and providing artificial ventilation that can include modes of mechanical ventilation. There are many ways to provide an airway and to deliver breathing support. The list below includes several options. Patients with respiratory arrest can be intubated without drugs. However, patients can be given sedating and paralytic drugs to minimize discomfort and help out with intubation. Pretreatment includes 100% oxygen, lidocaine, and atropine. 100% oxygen should be administered for 3 to 5 minutes. The time depends on pulse rate, pulmonary function, RBC count, and other metabolic factors. Lidocaine can be given in 1.5 mg/kg IV a few minutes before sedation and paralysis. The purpose of administering lidocaine is to blunt the sympathetic response of an increased heart rate, blood pressure, and intracranial pressure caused by laryngoscopy. Atropine can be given when TEENren produce a vagal response, evidenced by bradycardia, in response to intubation. Some physicians even give out vecuronium, which is a neuromuscular blocker to prevent muscle fasciculations in patients over 4 years old. Fasciculations may result in muscle pain on awakening. Laryngoscopy and intubation are uncomfortable procedures, so etomidate may be delivered. Etomidate is a short-acting IV drug with sedative analgesic properties. The drug works well and does not cause cardiovascular depression. Ketamine is an anesthetic that may be used as well, but it may cause hallucinations or bizarre behavior upon awakening. Thiopental and methohexital may be used as well to provide sedation, but they tend to cause hypotension. [12]. A tracheal tube is inserted into the trachea through the mouth or nose. Endotracheal tubes contain high-volume, low-pressure balloon cuffs to minimize air leakage and the risk of aspiration. Cuffed tubes were made originally for adults and TEENren over 8 years old, but cuffed tubes have been used in infants and younger TEENren to prevent air leakage. Cuffed tubes can be inflated to the extent needed to prevent air leakage. The en
