GUARANTEED SUCCESS
Stridor High-pitched wheezing sound caused by disrupted
airflow, often indicating an upper airway obstruction.
Crackles Discontinuous, popping sounds often heard in
conditions like pneumonia or pulmonary edema.
Wheezes Continuous, high-pitched whistling sounds due to
narrowed airways, commonly found in asthma and COPD.
Nasal Cannula (24-44% O2, up to 6 L/min)
Check for skin breakdown in nostrils and behind ears.
Can cause nasal dryness; use water-soluble jelly.
COPD patients should not exceed 4 L/min.
,Simple Face Mask (40%-60% O2, minimum 5 L/min)
Used for mouth breathers.
Remove during meals and use nasal cannula instead.
Monitor for aspiration risk
Partial Rebreather Mask (One-third exhaled air rebreathed)
Ensure reservoir bag stays inflated
Maintain bag inflation at one-third to one-half full.
Avoid in COPD patients.
Non-Rebreather Mask (Highest O2 concentration, ~90%)
One-way valve prevents room air entry.
Used for unstable patients needing intubation.
Ensure valves are functional
Venturi Mask (Most precise O2 concentration without
intubation)
Used in COPD patients to maintain controlled oxygenation - 40%
, Switch to nasal cannula during meals
High-Flow Nasal Cannula (Above 6 L/min)
Preoxygenation before suctioning.
T-piece adapter -used to wean pt off ventilator
-can be used with endotracheal, nasotracheal, or tracheostomy
tube
-used for *spontaneous breathing trial*
Ensures humidification
clean out the condensation that build up in tubing.
Non-Invasive Positive Pressure Ventilation (CPAP/BiPAP)
CPAP: Continuous airway pressure.
BiPAP: Pressure variation between inhalation and exhalation.
Droplet Precautions: Used for infections like pneumonia,
requiring surgical masks and patient isolation.
Airborne Precautions: Used for tuberculosis, requiring N95
masks and negative-pressure rooms.
