Slide 4 Copyright © 2007, 2004, by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved. General Impression of the Patient The general impression is formed to determine priority of care and is based on the EMTs immediate assessment of the environment and the patient's chief complaint.  Determine if the patient is ill or injured.  Reconsider mechanism of injury.  Patient data  Age, sex, race  Identify and treat life-threatening conditions.

Slide 13 Copyright © 2007, 2004, by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved. Assess the Infant’s or Child’s Airway   Place head in a sniffing or neutral position.   Be careful not to hyperextend the neck.   Slightly extend the head and neck of the child (1 to puberty) if no trauma is present.

Slide 14 Copyright © 2007, 2004, by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved. Infants and Children   Look carefully for signs of   Nasal flaring   Seesaw breathing (alternate use of chest and abdominal muscles during breathing)   Retractions of the chest wall when assessing for inadequate breathing   When needed, provide positive- pressure ventilation.

Slide 15 Copyright © 2007, 2004, by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved. Assess Breathing   Look, listen, and feel method   Look for chest and abdominal movements, accessory muscle use, and retractions.   Listen for air movement and abnormal sounds of breathing.   Feel for warm air from the lips and mouth.

Slide 16 Copyright © 2007, 2004, by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved. Adequate Breathing  Rhythm  Regular  Irregular  Quality  Breath sounds — present and equal  Chest expansion — adequate and equal  Minimum effort of breathing  Depth (tidal volume) – visible chest rise

Slide 17 Copyright © 2007, 2004, by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved. Adequate Breathing Rate  Adult: 12-20/minute  Child: 15-30/minute  Infant: 25-50/minute

Slide 18 Copyright © 2007, 2004, by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved. Review of Definitions   Respiratory distress   Any patient who experiences difficulty breathing and increased work of breathing as evidenced by dyspnea, accessory muscle use, retractions, increased respiratory rate, cyanosis, and other signs   Respiratory failure   A state when the respiratory system can no longer support life   Failure of the respiratory system to adequately remove carbon dioxide and deliver oxygen   Evidenced by multiple signs Altered mental state, decreased breath sounds, very rapid or slow respiratory rate, minimal chest rise, cyanosis   Respiratory arrest   Complete cessation of breathing

Slide 19 Copyright © 2007, 2004, by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved. Respiratory Distress  Shortness of breath  Agitation or restlessness  Active accessory muscle use  Retractions  Cyanotic skin  Increased pulse rate  Increased respiratory rate

Slide 21 Copyright © 2007, 2004, by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved. Respiratory Failure Inadequate Breathing  Depressed mental state (e.g., responsive to voice, responsive to pain, or unresponsive)  Rate – very fast or very slow  Rhythm — irregular  Quality  Breath sounds — diminished or absent  Chest expansion — unequal or inadequate  Depth (tidal volume) — inadequate/shallow  Cyanotic skin color
