A patient with suspected acute coronary syndromes (ACS)
is placed on a cardiac monitor. The patient is complaining
of dyspnea and is given supplemental oxygen. The provider
determines that the oxygen is effective based on which
SaO2 level?
When a patient presents with potential ACS, the patient
should have oxygen administered to maintain an SaO2 of at
least 94%.
,A patient experiences cardiac arrest, and the resuscitation
team initiates ventilations using a bag- valve-mask (BVM)
resuscitator. The development of which condition during
the provision of care would lead the team to suspect that
improper BVM technique is being used?
Complications can occur with the use of a BVM resuscitator
due to improper technique. Delivering excessive volume or
ventilating too fast creates excessive pressure that can
damage the airways, lungs and other organs. Excessive
volume can lead to tension pneumothorax.
Assessment of a patient reveals an ETCO2 level of 55 mmHg
and an arterial oxygen saturation (SaO2) level of 88%. The
provider would interpret these findings as indicative of
which condition?
An SaO2 level of less than 90% (PaO2 of less than 50 mmHg)
accompanied by ETCO2 values greater than 50 mmHg is
indicative of respiratory failure.
A healthcare provider initiates ventilations to ensure
adequate breathing and oxygenation. While ventilations are
being performed, capnography is established to evaluate
the adequacy of the ventilations. The healthcare provider
, determines that ventilations are adequate based on which
end-tidal carbon dioxide (ETCO2) value?
