Chapter 6: ACLS Respiratory Arrest (With Pulse) Algorithm

Respiratory arrest known as apnea is the absence or cessation of breathing, generally caused by cardiogenic shock, cardiac arrest, drowning and trauma. The normal heartbeat rate either goes down or is absent.

Respiratory Arrest Causes

  • Overdose of drugs: heroin, morphine, codeine, narcotics, anesthetics, and barbiturates
  • Injury or infection in the CNS that alters the pressure of the cerebrospinal fluid
  • Stroke, irregular heartbeats, cyanide, CO poisoning, heart attack, and other cardiac problems

Respiratory Signs And Symptoms 

  • Difficulty breathing: stridor, wheezing, etc.
  • Loss of consciousness
  • Cyanosis or blue coloration of skin
  • No passage of air from nose and mouth
  • Low levels of oxygen in blood
  • Complaining of difficulty in breathing
  • No chest rise and fall

This section will cover assessment, intervention, and management of an unconscious, unresponsive adult in respiratory arrest with a pulse.  Both BLS and ACLS Survey are used to manage patients in respiratory arrest.

Normal respiratory rate is 12-20 breaths/minute. Normal tidal volume is 6-8 mL/kg. If the respiratory rate is < 6 breaths/minute, assisted ventilation is required, either through bag-mask or advanced airway with 100% oxygen.

Scenario:  You are a nurse in the ICU unit and you see a patient complaining of chest pain. A few seconds later the patient lies completely motionless. There are a few agonal gasps and you start to notice the patient turning cyanotic. 

Respiratory Arrest Assessment

  1. Check for response – Tap and ask “Are you alright?” and look at chest for movement for maximum of 10 seconds
  2. Check carotid pulse (maximum of 10 seconds) and note pulse is present
  3. Call the doctor on duty

Respiratory Arrest Intervention

  2. Start bag-mask ventilations at a rate of 1 breath every 5-6 seconds or 10-12 breaths per minute

Respiratory Arrest Management: ACLS Survey

  1. If bag-mask ventilation is not adequate, insert oropharyngeal (OPA) or nasopharyngeal (NPA) airway
  2. Administer oxygen: maintain a saturation of ≥94% on pulse oximetry
  3. Continue bag-mask ventilations for 1 minute

Review of advanced airways

Bag-Mask Ventilation: This device has a ventilation bag attached to a face mask and provides positive pressure ventilation of 600 ml tidal volume.

Oropharyngeal Airway (OPA): used in patients whose airway might be obstructed by the tongue or relaxed upper airway muscles. This device is only used in unconscious patients, but not in conscious or semiconscious patient where it could stimulate gagging or vomiting.

Nasopharyngeal airway (NPA): used as an alternative to OPAs and can be used in a conscious or semiconscious patients. NPAs are usually inserted when inserting OPAs is difficult or dangerous.

Advanced Airway Tools and Techniques

There are many different devices used for advanced airway access and depends upon the training of the individual administrating the technique.

  1. Laryngeal mask airway
  2. Laryngeal tube
  3. Esophageal-tracheal tube
  4. Endotracheal tube

Interventions below are used during the BLS & ACLS Surveys:

  • Opening airway
  • Giving adequate oxygen
  • Providing basic ventilation
  • Suctioning

Note: Be careful of excessive ventilation. Excessive ventilation can cause a lot of problems because it increases intrathoracic pressure, reduces venous return to heart and blocks cardiac output. It can also cause gastric inflation and patient may be inclined to vomit and aspirate the gastric contents.

Precaution for trauma patients with a known or suspected C-spine injury:

Avoid moving the patient’s head, neck, and spine. Perform jaw-thrust without head extension, and have another team member stabilize the patient’s head as you insert the airway.

Learning Outcomes:

You have completed Chapter VI. Now you should be able to:

  1. Know the signs and symptoms for Respiratory Arrest
  2. Understand how BLS and ACLS surveys are used in respiratory arrest
  3. Recognize the respiratory arrest clinical scenario
  4. Recognize the different airway devices
