Ati Airway Management

Adult ATI: Airway Management Ch. 53

what does managing compromise include-respiratory assessment
-measuring vital signs: O2 sats via pulse oximetry
-administration of oxygen
what does administering oxygen do for ptshelps maintain adequate cellular oxygenation for clients who have many acute and chronic respiratory problems or are at risk for hypoxia
what kind of pt’s need to be administered oxygen-pt’s who have acute/chronic respiratory problems
(hypoxemia, cystic fibrosis, asthma)

=pt’s who are at risk for developing hypoxia
(resp. illness, circulatory impairment)

what is a nursing priority with airway managementmaintaining a patent airway
what is involved with maintaining a patent airway-mobilizing secretions
-suctioning airways
-managing artificial airways (endotracheal tubes, tracheostomy tubes)

promotes adequate gas exchange and lung expansion

pulse oximetera device with a sensor probe that attaches securely to the fingertip, toe, bridge of nose, earlobe, or forehead with a clip or band
what does a pulse oximeter domeasure pulse saturation (SPo2) via a wabe of infrared light that measures light absorption by oxygenated and deoxygenated hemoglobin in arterial blood
what does SPO2 reflectthe percent of saturation of hemoglobin (SaO2)

when the SaO2 is greater than 70 percent

how much of the atmospheric air is oxygen21 percent
oxygen rates vary to maintain…an SpO2 of 95-100 using the lowest amount of oxygen to achieve the goal without risking complications
FiO2 Fraction of inspired airthe percentage of oxygen the client recieves
what findings during your assessment would cause you to need the pulse oximetry-increased work of breathing
-changes in respiratory rate or rhythm
-adventitious breath sounds
-restlessness, irritability, confusion
what are some interventions that can be done if you have a pulse oximetry reading of less than 90% (indicating hypoxemia)–confirm probe placement

-confirm that o2 delivery system is functioning and that client is receiving the prescribed o2 levels

-place the client in semi-fowler’s or fowler’s position to promote chest expansion and to maximize ventilation

-encourage deep breathing

-remain with the client and provide emotional support to decrease anxiety

what is an acceptable range of the pulse ox.91-100 percent

some illnesses states can allow from 85-89 percent

readings of less than 90 reflect hypoxemia

what reasons may cause a low pulse ox readingolder adults
clients who have darker skin
poor peripheral blood flow
too much light
low hemoglobin levels
nail polish
what is oxygen therapy used fortreating hypoxemia (low levels of arterial oxygen)
early manifestations of hypoxemia-tachypenia
pale skin and mucous membranes
elevated blood pressure
use of accessory muscles, nasal flaring, tracheal tugging, adventitious lung sounds
what are late manifestations of hypoxemiastupor
cyanotic skin, mucous membranes
cardiac dysrhythmias
what are nursing actions that need to be considered with giving oxygen therapy-monitor respiratory rate and pattern

-minitor level of conciousness

-monitor SpO2 and ABG

-provide ox. therapy at lower liter flow that will correct hypoxemia

– make sure mask is placed on face correctly

– assess/monitor for hypoxemia/hypercarbia (restlessness, hypertension, headache)

-listen to lungs for breath sounds

-assess/monitor pulse ox

-promote oral hygiene

-encourage turning, coughing, deep breathing and use of incentive spirometry and suctioning
