Respiratory System: "On Future"

Stridor

upper airway obstruction

Lateral Recumbent

Patient turned onto their side. Best position for when suction is required.

Inhalation

Negative Pressure. Active process in which the muscles of the rib cage and the diaphragm contract.

Exhalation

Positive Pressure. Passive process during which the intercostal muscles and the diaphragm relax.

Tidal Volume

The amount of air moved in one breath.

Mechanics of breathing disrupted

Air cannot be moved in and out of the lungs caused by:

1. Patient is stabbed in the chest.

2. Patient looses nervous control of respiration.

3. Patient sustains painful chest injuries.

4. Patient has airway problems; such as bronchoconstriction.

Hypoxia

Low levels of oxygen

Hypercapnia

High levels of carbon dioxide

Dyspnea

Respiratory distress

Causes of Hypoxia

1. Patient is trapped in a fire.

2. Patient OD's on a drug with depressing effects on the respiratory system.

3. Patient has a heart attack.

4. Patient has a stroke.

5. Patient is in shock.

Bronchitis

Can be identified by patient coughing up blood.

Respiratory Infection

Can be identified by patient coughing up green mucous/phlegm.

If patient has adequate breathing but are in respiratory distress?

Provide supplemental oxygen.

When oxygen cylinder is unsecured?

DO NOT LEAVE STANDING UP

Pressure Regulator Safe Pressure?

30-70psi

Flowmeters

Allows control of oxygen in liters per minute.

Humidifiers

Can be connected to flowmeter to provide moisture to the dry oxygen coming from the supply.

Nonrebreather Mask

Best way to deliver high concentrations of oxygen to a breathing patient.

Minimun/Maximun Flow Rate?

Min: 8lpm | Max: 12-15lpm

Nasal Cannula

Delivers no more than 4-6lpm.

Partial Rebreather Mask

Delivers 40-60% oxygen at 9-10lpm

Hyperventilation Is?

Faster than 20 breaths per minute, deep breathing.

Clues of Periphery?

Cyanosis, Lips Pursing, Fingers Clubbing, & Nasal Flaring

Hemothorax

Small amount of blood in thorax(<400mL): Little to no change in patient.

Large amount of blood in thorax(>1,000mL): Restlessness, anxiety, pallor, pleuritic chest pain, hemoptysis, dyspnea, or air hunger.

Signs of shock with loss of blood volume >30%(1,500-2,00mL)

Tension Pneumothorax: Symptoms?

Hypotension, Tracheal Deviation, and Jugular Vein Distention(JVD).
