Your BLS engine company is dispatched to a “difficulty breathing” call and your ALS rescue is still in the process of delivering their previous patient to the hospital. Dispatch is sending the next closest rescue, but the responding unit has just notified you that they are held up by a train. You arrive on scene, grab your O2 bag and jump kit and head inside. You and your fellow EMTs are on your own, at least for the next several minutes. You had better be prepared to assess and initiate treatment for a patient in respiratory distress!
Like every patient, treatment begins with an assessment. And when the patient is having difficulty breathing, every second counts. So let’s review the basics of respiratory assessment before we take a look at the techniques involved in basic airway management.
Assessing the patient in respiratory distress
Patients in respiratory distress are usually easy to spot, so your initial assessment begins with a quick visual exam before moving on to your physical assessment. Here are some considerations:
- Patient Position – Patients in distress will assume a position of comfort when possible, which usually includes sitting up straight to maximize airflow and lung expansion. They may use accessory muscles, appear agitated or frightened, and in extreme cases, be cyanotic.
- Auscultation – If possible, have your patient sit upright when listening to breath sounds and be sure to place your stethoscope directly on the skin. Have them take slow, deep breaths, if possible, and listen for any abnormal lung sounds, which can include:
- Rhonchi – Continuous low pitched sounds resulting from mucus in the airway.
- Wheezes – Continuous high pitched sounds resulting from a constricted airway.
- Crackles (aka rales) – Discontinuous sounds caused by mucus or fluid in the airway; also caused when collapsed airways or alveoli pop open.
- Stridor – Loud, high pitched sound (seal bark) caused by swelling or obstruction above the glottis opening.
- Respiratory Rate – Assess for rate, depth, and rhythm.
- Palpation – Place hands directly on the chest wall during respiration to assess lung status, chest expansion, and skin (subcutaneous emphysema).
Basic airway management
Once you have assessed your patient and determined that they are truly in respiratory distress, it is time to take action. Here are your options when it comes to basic airway management:
- Positioning – Allow the patient to assume the position of comfort, as long as you do not suspect trauma. Consider elevating or turning the backboard to assist respiratory efforts and protect the airway in trauma patients. If the patient is unresponsive, position the airway using:
- Head tilt-chin lift – Most common means of opening the airway in the non-trauma patient.
- Tongue-jaw lift – Effective means of opening the airway and checking for foreign body obstruction; not used during artificial ventilation.
- Jaw thrust – Used to open the airway in suspected trauma.
- Airway Adjuncts – The OPA (oropharyngeal airway) can be used along with manual airway maneuvers to provide a patent airway in the unresponsive patient. Make sure the patient does not have a gag reflex when using the OPA and the proper sized device should reach from the patient’s central incisor to the angle of the jaw. Depending on your local protocols, you may have other airway adjuncts at your disposal, such as the Combitube or LMA.
- Supplemental Oxygen – Provide supplemental oxygen at either low- or high-flow, depending on your patient’s needs, using either a nasal cannula or a non-rebreather mask. Oxygen has few side effects and is the most commonly administered drug in the prehospital setting, so be prepared to treat your patient accordingly!
- Suction – There is no replacement for effective suction, so keep your portable suction unit on hand at all times and don’t hesitate to use it. It is one of the most basic, yet potentially lifesaving skills at your disposal.
There are many effective ways for EMTs to jump start the treatment of patients in respiratory distress, so keep your skills sharp and be ready to take the lead in airway management.
